Abstract
A novel compact microstrip dual-band bandpass filter (BPF) using short-stub loaded half-wavelength resonator with multiple transmission zeros and good selectivity is proposed in this letter. The characteristics of the dual-mode resonator are investigated by using even-odd mode analysis. To improve filter selectivity, a new structure of hook feed line of couple-line is introduced to produce six transmission zeros at the adjacent two passbands. A prototype of dual-band bandpass filter for WLAN (2.4 GHz) and WiMAX (3.5 GHz) applications is designed and fabricated for demonstration. Good agreement is observed between the measured and the theoretical expectation. © 2012 IEEE.
