5G and 6G Antenna: Technology and Markets Moving Forward
Dr. Yu-Han Chang, Lead 5G and 6G Research Analyst - IDTechEx
After years of waiting, 5G has finally become a reality. Over the past few years, we have seen many new field trials and an accelerating number of commercial rollouts. 5G, in comparison with previous generations of mobile networks, provides much larger bandwidth, lower latency, higher reliability, and many more connections. As such, 5G has the potential to enable the internet and the intelligence of everything, bringing a disruptive and life-changing effect on our society.
As of mid-2021, the majority of the 5G commercial rollouts are still focused on the sub-6 GHz frequency bands. However, we expect to see more rollouts with mmWave frequency bands in the coming years. Whilst the sub-6 GHz presents moderate technical challenges, the high-frequency mmWave operation is setting out new and significant challenges across the whole supply chain, including antenna systems.
This presentation will not only cover the current status of 5G antenna technology and business but also emerging antenna technology for 5G mmWave systems and future 6G.
Addressing the Complexity of Antenna Characterization in Realistic Use Cases by Combining Measurements with Full-Wave Electromagnetic Simulations
Beniot Derat, Senior Director for Systems Developments & Customer Project Implementations - Rohde & Schwarz
With the ubiquity of wireless communication technologies and their increase in complexity, challenges in antenna characterization, over-the-air (OTA) measurement and regulatory compliance assessment of radiating equipment are multiplying. New techniques are required to address the increased demand for testing capacity and evaluate electromagnetic fields in realistic use and antenna integration conditions. The introduced approach of augmented OTA owns the potential to meet some of these needs, by converging near-field measurement techniques with advanced processing and numerical modelling. The relevance of this combination is demonstrated through practical applications, including the evaluation of near and far-field distributions for car-integrated antennas without involving a physical vehicle, and the assessment of user equipment or base station near-field human exposure quantities, the power density and Specific Absorption Rate (SAR), solely based on free-space OTA measurements.
Challenges and Solutions for 5G New Radio (NR) OTA/PTCRB Carrier Certification
Nicolas Stamber, Director of OTA - CETECOM USA
Norm Smith, Director of Sales & Marketing - CETECOM USA
5G New Radio (NR), brings with it a slew of new 3GPP standards requirements and carrier certification testing challenges for device manufacturers and test engineers. As an example, the tight integration of mm Wave antenna arrays with 5G NR radio modules necessitates the use of over the air (OTA) testing rather than conducted measurements for many of these requirements.
This paper provides valuable insights into the types of challenges pioneering device manufacturers often face when striving to get their products through carrier certification in a timely manner in order to get them first into the global market place. We examine and expose some of the pitfalls to avoid and valuable lessons learned. CETECOM’s many years of OTA/PTCRB certification experience, through multiple generations of cellular technology standards, uniquely positions it to expose the risks that can result in catastrophic certification failures that can set a device product launch back many months, at considerable cost, sometimes resulting in a complete failure to get to market at all.

5G Success Hinges on Bringing mmWave Indoors
Dr. Andrew Jun, Chief Technology Officer - ADRF
The rapid development of 5G mmWave is necessary for providing high speed and ultra-reliable low-latency communications (URLLC) that are expected to power our innovations of tomorrow. This includes mission-critical IoT, scalable VR/AR use cases, supercomputing and much more. However, at present, mmWave can only travel short distances and is easily disrupted by anything such as building materials, foliage, and walls. All of the promising 5G applications are contingent on buildings being able to receive excellent 5G coverage indoors.
With frequent environmental interferences, 5G stakeholders are looking to a number of new and tried-and-true methods and equipment to overcome these obstacles including beam forming, mmWave relay, the use of DAS, repeaters, small cells as well as Massive MIMO. Without these, a nationwide 5G network is impractical because of the substantial amount of base stations essential to supporting it. 5G connectivity is most important in buildings since 80% of data traffic is now generated in indoor environments. In this presentation, the presenter will speak about the different ways that carriers, OEMs and integrators are looking to tackle the challenges of indoor 5G coverage to support technologies of the future across industries.
Cracking the Code for 5G mmWave with Holographic Beam Forming
Eric Black, CTO - Pivotal Commware
As mobile operators move 5G millimeter wave (mmWave) deployments forward, solutions for achieving coverage at scale with minimal cost remain elusive. Holographic Beam Forming (HBF) has cracked the code, revolutionizing the landscape for enabling 5G mmWave access and improving delivery economics.
HBF-powered repeaters extend mmWave coverage outdoors and allow the signal to penetrate indoor environments. When combined with new network modeling capabilities and intelligent beam management systems, operators are equipped with an entire mmWave ecosystem that provides precise placement of network elements—such as repeaters and 5G base stations—capable of optimizing network connectivity for subscribers and minimizing total cost of ownership.
In this session, CTO of Pivotal Commware Eric Black will discuss how a mmWave ecosystem based on HBF can be deployed to expand 5G mmWave coverage in public spaces, homes and enterprises. This approach ultimately reduces capital, operating and siting costs otherwise required to deploy costly base stations. He will also discuss how HBF solves mmWave’s most vexing challenges and turns the perceived weaknesses of mmWave propagation into strengths.
Lunch Break - Dedicated 1 on 1 Meeting Time
Dr. Theodore Anderson, CEO - Haleakala R&D, Inc.
This presentation will explain novel concepts for the potential use of plasma antennas for cellular systems improvement for 5G and future generations. The targeted application is the use of smart plasma antennas to improve the performance and capacity while reducing the equipment required (towers, antennas, transmitters & power levels). The plasma antenna can have relatively high gain, directivity, and low sidelobes in a compact size, compared to conventional antennas. It can sweep focused beams at extremely high speed, e.g. 10’s of degrees per microsecond, or step from one direction to another in microseconds. It has very low sidelobe levels due to its’ much-reduced diffraction effects at plasma boundaries, hence, high isolation and low crosstalk interference.
The smart plasma antenna has the advantage of simultaneously satisfying beamforming techniques and MIMO techniques. The MIMO techniques will overcome deep fading. This is in regard to OFDM and SFBC. This means that we build a vector or one dimensional array of smart plasma antennas to satisfy both beamforming and MIMO. Another key advantage of smart plasma antennas is that there is built in protection against EMI with the cylindrical annular ring of plasma tubes.
The greatest advantage of the plasma window antenna for cellular use is its’ reconfigurability. Not only can the beam be rapidly stepped from one direction to another, without physical movement, but the gain and beamwidth can also be rapidly adjusted. This could be utilized to continuously optimize the system. Hence, the term “smart antenna” is an appropriate description.
5G Beamforming: New Patterns for a New Network
Marty Zimmerman, Engineering Fellow - CommScope
As many as 1/3 of global wireless operators implemented beamforming in 4G networks, either for mobile wireless or fixed wireless access. This is because beamforming focuses transmitted power, improving signal strength to the intended recipient while reducing interference to other network devices. In 5G, beamforming will be almost universally used for the same reasons, as well as to minimize interference from other signals. However, the beamforming patterns will be different for 5G than for 4G, so RF planners must learn how to work with the new options.
In this presentation, the speaker will discuss the benefits of beamforming for 5G and how it is done. The presentation covers the following topics:
Benefits of beamforming for mobile wireless
New beamforming patterns for 5G
Tradeoffs between Massive-MIMO and 8T8R beamforming
Advancements in 5G Handset Antennas
Tayfun Özdemir, Ph.D., President/CTO - Monarch Antenna, Inc.
The 5G communication infrastructure and the protocol have many features to support many applications other than personal communications and many devices (in addition to handsets). Therefore, it is important to understand what aspects of the 5G standard are relevant to the handsets and recognize that the handset antennas are at the end of the food-chain that includes the I/O peripherals, baseband processor and RF Front End, to name the major components.
This requires a good understanding of the 5G world and hence, at the 2020 edition of this conference, we presented these requirements. At this year’s event, we will present the antenna designs that attempt to satisfy those requirements because there are fundamental limits on antenna performance due to size and placement restrictions within the handset. Naturally, 5G is more than just the communication between the base-station and the handset and there are other 5G-enabled devices too but this talk will be limited to handsets.
Spectrum Genesis Hyperbeam Antennas
Dr. John Howard, Founder & President - Electromagnetic Technologies Industries, Inc.
Steve Jalil, Systems Engineer - Electromagnetic Technologies Industries, Inc.
In this paper ETI’s Hyperbeam Multiple Beam technology, capable of up to 32 beams in a 120 degree sector or up to 24 beams in a 90 degree sector is presented. These Spectrum Genesis Hyperbeam Antennas can repeat the full spectrum bandwidth available to a wireless provider up to 32 times in a 120 degree sector or up to 24 times in a 90 degree sector, avoiding therefore the cost of purchasing additional expensive spectrum assets.
The Spectrum Genesis Hyperbeam Antenna is a multi-beam antenna system with beamforming technology that can be used to increase quality of service, network capacity, and full spectrum usage to meet the current and future demand of data usage and network capacity. The antenna main beam crossings can be set according to customer requirements. Main beam crossings can be reduced to as low as 20dB if required, thus minimizing the common area between two beams. Sidelobe levels can be reduced to levels below 20dB permitting high signal to noise ratios. Each beam provides a capacity and throughput multiplication over a traditional cell site. Frequencies can be reused in a sector, resulting in a spectrum multiplication of up to 32 times. With the use of multiplexers several channels can be combined and transmitted in each beam providing multi-band/ multi-channel transmission with a single antenna system to further increase user capacity and data throughput.
Supporting 5G Network Rollouts with Interleaved Passive-Active Antennas
Mike Wolfe, Global VP of Wireless Network Engineering - CommScope
Supporting the increasing demands for mobile broadband requires high-performance network solutions. 5G networks can deliver more capacity than earlier mobile technologies, however they require the use of new antenna systems. Existing cell-sites are often used for these deployments, but can have space and/or other constraints, which can be problematic. Overcoming deployment challenges is key to the rollout and success of 5G. Hybrid antennas combine both passive and active radio elements into the same modular antenna platform and are an ideal solution. While the laws of physics present some challenges in realizing antennas that are compact and lightweight, clever engineering can overcome them.
In this presentation, the speaker will discuss Interleaved Passive Active Antenna (IPAA) technology and applications. The IPAA features a multi-port wideband passive antenna supporting multiple frequency bands in the range 700-2700 MHz as well as different active antenna elements with TDD beamforming functionality in the mid-band, 3.3-4.2 GHz. Recognizing the continued importance of existing network performance, the IPAA design cleverly interleaves the active antenna array with the low-band antenna elements to avoid re-optimizing existing networks at 700-900 MHz. The presentation covers the following topics:
The need for IPAAs
IPAA technology – interleaving passive antenna elements and -active radio platforms
Electronically-Steerable Antennas vs Dielectric Waveguide Antennas in 5G Applications and Beyond
Marwan Krunz, ED2 Chief Scientist representing partner Wilson Electronics
By now, it has become clear that transitioning from the existing LTE technology to 5G is by no means incremental, especially for 5G systems that operate in the millimeter-wave (mmWave) spectrum. mmWave frequencies suffer from high signal attenuation loss, poor penetration of walls/objects, and limited scattering.
Different antenna technologies have been advocated for mmWave operation in 5G systems. The most common form is the electronically steerable arrays. Dielectric waveguide antennas are another option. The two antenna technologies will be evaluated.
From a 5G and Beyond (B5G) perspective, learn how the dielectric rod is a disruptive antenna technology that offers significant advantages over state-of-the-art electronically steerable arrays, in both indoor and outdoor scenarios. Specifically, a single rather inexpensive dielectric rod replaces an electronically steerable array/subarray made of tens of patch antennas. With a dielectric rod, no phase shifters are needed, resulting in significant reduction in cost, power consumption, and silicon area.
