35 GHz Prolonged Stopband Lowpass Filter using Multi-Resonator Structure

Abstract

This work presents highly suppressed microstrip lowpass filter design having prolonged stopband width up to 38 GHz. The 14th harmonics rejection is also accomplished using the multi resonator structure. The LC equivalent circuit of the proposed filter is developed as per the the tuning of the first transmission zero. The high performance multi resonator filter circuit is designed for S- band communication applications.
