Applied Mesh Technologies Enhances Performance of Wireless Mesh Network Through Its New Relationship with Monarch Antenna, Inc.

Applied Mesh Technologies, a provider of wireless telemetry equipment, has announced the successful integration of Self-Structuring Antenna (SSA) technology provided by Monarch Antenna, Inc. Integration of Monarch’s cognitive SSA greatly improves the performance of Applied Mesh Technologies’ line of wireless telemetry products. SSA extends range in weak signal conditions, improves signal quality in severe RF multipath environments, and improves wireless network selectivity.

“Integration of Monarch’s technology greatly improves the performance of our devices employing 802.15.4 networking, this being particularly true given the difficult RF environments presented by our customers.” said Charles Melvin, vice president of Engineering, Applied Mesh.

Rogers to Feature RO4000 and RO3000 Antenna Grade Materials at 2008 Antenna Systems Conference

Rogers Corporation’s Advanced Circuit Materials Division (booth #7), the largest producer of high frequency materials, serving the antenna and short-range wireless industry, will feature its RO4000 and RO3000 antenna grade high frequency circuit materials at the upcoming Antenna Systems & Technology show in Austin, Texas on September 25 and 26.

Available with both thick and thin cladding, cost-effective RO3000 and RO4000 laminates are antenna grade materials that feature low passive intermodulation (PIM), low loss, and are ideal for use in antennas for 3G, WiMAX and LTE cellular base stations, satellite earth stations, GPS systems and RFID readers.

With its higher thermal conductivity for increased power-handling capability, RO4000 laminates meet the needs of the antenna market for an enhanced-performance option to traditional PTFE materials. RO4000 materials are glass-reinforced hydrocarbon/ceramic laminates with excellent dimensional stability and tight dielectric-constant tolerance across the panel. Its low dielectric loss tangent helps deliver high-performance antennas designs reliably and consistently. Low-loss RO4000 materials can be used in many applications where higher operating frequencies limit the use of conventional circuit board laminates

RO3000 series laminates are durable PTFE-based circuit materials with consistent mechanical properties. They combine lower loss and minimal variation in dielectric constant with a cost-effective price for commercial applications requiring higher performance. RO3000 materials can be used in applications through 40 GHz.

Directed Perception’s PTU-D300-RF is a modular Azimuth/Elevation antenna positioner the supports all antenna types. Features include continuous azimuth rotation, real-time control for tracking and options such as geo-pointing and Ethernet control.

The PTU-D300-RF is designed to support a range of fixed and mobile antenna and communications laser positioning requirements for satellite tracking, microwave communications, and other surveillance and communications applications. The PTU-D300-RF offers a price/performance not previously available in off-the-shelf antenna positioners. The extremely rugged all-in-one design is compact and has flexible mounting options. A 360° continuous-pan option supports pass-through of antenna signals from DC to 18 GHz. An available software API supports integration with custom applications. Geo-pointing and stabilizations options are available.

The integrated design of the PTU-D300-RF provides a complete turn-key positioning solution for fast, accurate, dynamic, computer-controlled positioning of antenna position through a wide range of motion. Sensor and communications systems designers can save months of product development time by using the PTU-D300-RF as a complete, drop-in antenna positioning solution.

Agilent Highlights Advanced Design System at Antenna Systems Conference

Agilent EEsof’s ADS (Advanced Design System) is a powerful electronic design automation software system. It offers complete design integration to designers of products such as cellular and portable phones, pagers, wireless networks, radar and satellite communications systems, and high-speed digital serial links.

ADS 2008 Update 2 brings tight integration of full 3DEM simulation into the ADS flow to enable the efficient design of cell phones, RF modules and antenna modules. The integrated flow eliminates many unnecessary steps in the design process, which halves the cycle time by cutting out two hours of manual data transfer and preparation per simulation run on standalone EM tools.

Momentum, a planar 3DEM simulator based on the Method of Moment (MOM) analysis of stacked planar structures is Agilent EEsof’s fastest and most memory-efficient simulator to deal with the higher levels of complexity in RF module design.

EMDS is a full 3DEM simulator based on Finite Element Method (FEM) of solving arbitrary 3D structures. It can take into account the finite dielectric brick structure of RF modules and the effects of bondwires and packages.

AMDS is a full 3DEM simulator dedicated to antenna design and modeling. It is based on FDTD (Finite Difference Time Domain) simulation technique and is well suited for analyzing electrically large structures such as antennas and the human body.

Within ADS, these three simulators can be used together for speed and accuracy of EM simulation. Because of their tight integration with circuit and system design flow, designers can efficiently co-design the RF module and antenna performance.

ADS represents the largest installed base of high frequency designers around the world with 62 percent of the total RF design and simulation market.
