The Design of Miniature UHF SAR Antenna

Mainly study the miniaturization, high gain and wideband of the UHF SAR antenna. Do research on reducing the radar antenna structure by changing the feed array manner. Put forward a type of array antenna with a reflecting prism, each element of which is a double-face printed H shaped antenna and the gain at 600 MHz of which can reach 16 dB. Both length and width of the antenna are smaller than 1 m, which is suitable to perform as small-sized and high performance SAR antenna on the limited flat roof of plane and satellite
