Abstract : This final report presents experimental results for a breadboard phased array. The breadboard consists of 24 square waveguide and septum polarizer elements, diode phase shifters, a feed network, and a microprocessor array controller. The breadboard is a part of a tent-shaped phased array SHF aircraft antenna for satellite communications. The tent array consists of four planar phased arrays and has a low profile streamlined configuration. It provides electrical scanning over a hemisphere and is capable of high power transmission. The design of the array is a trade-off of the key parameters including gain, coverage, aerodynamic impact, high power transmission, and array packaging. A study was performed to drive an optimum array configuration. Design considerations and study results were presented in the Interim Report. Experimental testing of the breadboard reported herein verified the concept of the tent-shaped phased array. Additional breadboard tests and further studies are recommended. The designs of 20dB and 30dB gain tent arrays are included. (Author)
