摘要

Based on conventional Wilkinson power divider, two compact multi- band equal power dividers ( PDs) employing stub loaded stepped-impedance resonators with defected microstrip structure (SL-SIR-DMS) is proposed in this paper. The proposed SL-SIR-DMS is analyzed by even/ odd mode method. It is found that different defected structures can lead to different frequency responses. In addition, by using DMS, tri-band and even quad-band responses can be easily achieved without increasing the resonator size. As verification, one tri-band equal PD and one quad-band one are fabricated. The predicted results on S parameters are compared with the measured ones and good agreement is found.
