【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.更多还原
