2008 Antenna Systems Conference Announces Pre-Conference Workshop

Antennas for Wireless Communications: Basic Principles & System Applications
This half-day short course will present the basic principles of antennas as applied to wireless communication systems. The fundamental types of antennas (electrically small, resonant, broadband, and aperture) will be discussed, including examples of popular antennas for base stations and for satellite, vehicular and handheld terminals. Array antenna basics will be introduced. Special considerations for popular systems such as cellular radio and ultra-wideband radio will be presented. The presentation will conclude with a photo presentation of antennas in practice.

WHO SHOULD ATTEND:
• Engineers involved in antenna design
• Wireless Systems Engineers
• Managers of application programs using antennas

WHEN:
September 24th, 2008 (1pm – 5pm)
Before the 2008 Antenna Systems Conference

WHERE:
Hyatt Regency Austin • Austin, Texas

INSTRUCTOR:
Dr. Warren Stutzman, Virginia Tech
Dr. Warren Stutzman has been Professor of Electrical and Computer Engineering at Virginia Tech for 38 years, including positions as department head, and as founding director of the Virginia Tech Antenna Group.

Zinwave, a pioneer of next generation in-building cellular and wireless technology, recently launched its 3000 Active Wideband Distributed Antenna System (DAS). Designed to support and aggregate a multiservice, multi-operator wireless environment, the Zinwave 3000 is the most cost-effective in-building coverage system. The system supports the full wireless spectrum, from 136MHz through to 2.7GHz on a single platform.

A true wideband system – no parallel service specific units and no cabling overlays – the Zinwave 3000 allows businesses and facilities to deploy a single centrally managed platform to support multi service/multi-operator wireless coverage. Any number or combination of services are supported – including 2G/3G to LTE; WiFi; WiMAX; TETRA; private mobile radio; RFID; DVB-H; etc – enabling simultaneous mobility for employees, consumers and emergency services. It is also the only active DAS system that can support Time Division Duplex (TDD) services.

The scalability and flexibility afforded by the Zinwave 3000 ensures wireless coverage can be delivered to the most complex of locations and structures, including multi-building campus sites, high-rise offices, or large complexes such as airports. The Zinwave 3000 can utilize single-mode (SMF) or multi-mode (MMF) fiber (with a coaxial option), allowing the use of existing fiber infrastructure where available.

Unique Design Gives Double-Ridged Waveguide Horn Antenna Optimized Gain
in EMC Testing

The R&S HF907 covers a wide frequency range from 800 MHz to 18 GHz. As a transmit and receive antenna, it can both generate disturbance and detect radiated emissions of devices under test (DUTs). During these measurements, the antenna's flat gain permits even illumination of the DUT. In EMC tests, manufacturers and operators of electronic equipment benefit from distortion-free radiation patterns and obtain exact results. In the past, conventional double-ridged waveguide horn antennas exhibited gain losses at one or more points in the frequency range, which was reflected in the radiation pattern.

The R&S HF907 is compact and weighs only 1.9 kg, which makes it ideal for use in EMC labs and test chambers – especially in connection with EMC test equipment and test systems from Rohde & Schwarz.
