Abstract
A novel modification of short backfire antenna ( SBA) is described in the paper, which has the advantages of high aperture efficiency, high gain, low side-lobe, simple structure, easy method to feed and so on. The added structure of choke on reflector is applied to increase the gain and to improve side lobe of the radiation pattern. The shape of double cone on sub-reflector is given to improve the bandwidth and VSWR of ports. At last, a fabricated prototype according the de-signed dimensions achieved from simulation and analysis is discussed, and the actual measured results is consistent with the simulated results. The novel SBA has the good performance that the gain of 19dBi is attained, and VSWR is lower than 1. 5 at the relative bandwidth of 12%.关键词
