AN L-BAND BACKFIRE ANTENNA USED IN THE MICROWAVE REMOTE SENSOR
-
摘要: 背射式天線具有增益高、副瓣低和結(jié)構(gòu)緊湊的特點(diǎn),但其頻帶較窄。本文得到的實(shí)驗(yàn)結(jié)果表明,它適于用作L波段微波輻射計(jì)的天線,而且能提高微波遙感系統(tǒng)的性能。

Abstract: The backfire antenna is a kind of compact structure, high gain and lower sidelobe antenna, but its bandwidth is limited. In this paper, the experimental results of the radiation characteristics of a backfire antenna at the L-band are presented. It is shown that the characeristics of the remote sensing system can be improved greatly by using this kind of antenna. -
