The short backfire (SBF) is a highly effective aperture antenna of simple and compact construction. Basically, it consists of three elements: two parallel reflectors, large and small, spaced a half-wavelength apart, which form a leaky resonant cavity, and a cavity feed (half-wave dipole, 1–3 waveguide or horn, 4,5 or...

The wireless communication industry is developing rapidly and wireless communication products, PDAs, laptops and cell-phones are becoming a necessity of life. Communication systems need a wide frequency bandwidth to transmit and receive multimedia information at high data rates. Mobile wireless communication products must be easily portable and cheap to...

In the fall, Northrop Grumman-developed C-band radar for the US Navy participated in the successful test of the Ground-based Midcourse Defense (GMD) system, marking the first time a Navy Strategic Systems Program radar has been used by the US Missile Defense Agency (MDA) to optimize data collection and enhance...

Raytheon Co.’s Navy Multiband Terminal (NMT) is the first advanced, next-generation satellite communications (SATCOM) system to successfully log on to and communicate with the US Government’s Milstar SATCOM system, using low and medium data rate waveforms.
