Abstract

A compact microstrip dual-band bandpass filter (DBBPF) with controllable bandwidth for each passband is proposed. Each passband is independently designed using two different dual-mode resonators. The proposed DBBPF has three transmission zeros. Two transmission zeros are generated by each dual-mode resonator. An additional transmission zero is generated by input/output port coupling. The DBBPF application is designed for 2.4/5.7 GHz WLAN. Experimental measurements are presented to validate the theory. © 2011 Wiley Periodicals, Inc.
