C-Band Transponder Antenna,
Abstract
This paper describes the design, fabrication, and test results of C-Band Transponder Antenna. The antenna is a light-weight, low-profile 32 element microstrip wraparound-type printed circuit antenna. The unit is formed and bonded to a balanced lightweight 11.5-inch diameter magnesium ring. This paper includes a description of the interactive graphics and computer-aided design (CAD) photo generation techniques and process control for large size (42 inches long) flexible circuit boards. Also described are the design of the antenna feed system, pin-diode transmit-receive switch and receiver solid-state electronics network layout using an asymmetrical stripline printed circuit board. The use of an asymmetrical circuit system is a novel approach to reducing weight and preventing feed system (microstrip) radiation losses while providing adequate antenna bandwidth. Finally, the paper describes the results of the prototype antenna testing. (Author)
