A Compact Lowpass Filter with Four Transmission Zeros Using Single-Sided Compact Microstrip Resonator Cells

Abstract:

A compact lowpass filter using two single-sided compact microstrip resonator cells （CMRCs）with low insertion loss and broad bandwidth is presented. The cutoff frequency is about 1.4 GHz, the insertion loss is less than 0.6 dB and the 20dB bandwidth is up to the range from 2.1 GHz to 9.8 GHz by means of introducing four transmission zeros through two CMRCs. In addition, the simulated results demonstrate that the proposed filter is characterized by a compact size, low insertion loss, sharp transition, low return loss and wide bandwidth.
