| Abstract: | A novel simple dual-mode microstrip circular patch bandpass filter with a small rectangle notch was proposed.The central frequency of the filter was 5.9 GHz,the max return loss surpassed –31.5 dB,the minimum insertion was – 0.7 dB in passband and the 3 dB fractional bandwidth was 23.73%.The measurement result is consistent with the software simulation result. |
