A bandpass filter with an elliptic response is presented based on a complementary compact microstrip resonant cell (CCMRC). It can be designed by following the traditional coupled resonator theory. An example filter is fabricated and measured. It is shown that the proposed elliptic response CCMRC has high selectivity, compact size, low insertion loss and a wide upper stopband, making it promising in microwave applications.
