摘要：
In this paper, a S-band widebeam waveguide slot cavity antenna with out-of-band anti-interference function is introduced. Firstly, it uses the eigenmode simulation to observe the cut-off frequencies of various modes and adjusts the relevant parameters to achieve the desired passband and stopband. Then, four radiation slots are etched on cavity, and the parameters are adjusted for widebeam and impedance matching. Finally, the simulation results are presented and discussed. The results show that the proposed antenna has the 10 dB impedance bandwidth from 2.96 GHz to 3.05 GHz, the 3 dB beamwidth of 110 degrees, and gain suppression of 10 similar to 35 dB compared with that without filtering units in stopband.
