Abstract

Aiming at spreading bandwidth of SAR, this paper puts forward a new type of prism radar antenna. The feed based on techniques of CPW is a two-component antenna array liking H printed by dubble plane overlap. The antennas frequency bandwidth gets to 2.2 times frequency and is designed larruping. VSWR within the bandwidth is less than 1.8, gain and the centural frequency is more than 9dBi. The paper analyzes antennas structure, presents VSWR and radiation direction plot by simulation and test. The result indicates: two-component antenna array printed by dubble plane overlap can be the new feed of UHF radar antenna.
