A tri-band two-way filtering power divider structure is proposed based on HMSIW. Dual-band filtering power divider is realized by etching semicircular slots on HMSIW. The third passband is achieved by loading open-stub without affecting two other passbands. The return loss is less than -20 dB in each passband with 3 dB fractional bandwidths of 3.75%, 9.3% and 0.61%. The measured results are in agreement with the simulated ones in this paper. The filtering power divider has the advantages of simple structure, easy integration, etc. It has a good application prospect.
