摘要
A novel structure of a compact microstrip dual-mode resonator is proposed for a dual-mode filter application. The proposed dual-mode resonator is miniaturized using an interdigital capacitor and stepped impedance structure, lit addition, the proposed dual-mode resonator provides two transmission zeros in the stopband. The dual-mode filter application is designed for 2.4 GHz wireless local area network (WLAN) with three transmission zeros. An additional transmission zero is generated in the filter application using a cross coupling capacitor between input/output ports. Experimental measurements are also presented to validate the theory.
