摘要
A novel multimode broadband square patch bandpass filter is proposed. The return loss of the filter is more than 11 dB and insertion loss is less than 1.2 dB within 3.47-5.22 GHz. This new filter has four transmission poles in the passband and the 3dB bandwidth is 48.9%. Measured results are in good agreement with simulated results.
