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. © 2010 Wiley Periodicals, Inc.
