Abstract :
Compact microstrip parallel-coupled bandpass filters with two capacitive cross-couplings for creating multiple transmission zeros are proposed. The locations of transmission zeros can be adjusted by varying the values of cross-coupled capacitances so as to improve the filter selectivity. Simple equivalent-circuit model is also established to facilitate the filter design. Specifically, two microstrip bandpass filters with compact size and good selectivity are implemented and carefully examined
