| Abstract: | To fulfill the demand of wideband high-performance auto-tracking feed,a feed made up of eight logic periodic monopole dual circular polarization beam antennas is designed.The design method and the feed theory are introduced.The feed is simulated by using the software of Ansoft HFSS and the simulation patterns are given.At last,the affections of amplitude and phase are analyzed.The simulation results indicate that the feed can form dual circular polarization beam at the frequency range from 1 to 12 GHz and has a good performance. |
