Abstract

This paper presents a novel elliptic shape defected ground structure (DGS) for low pass filter (LPF) applications. An equivalent RLC circuit model is presented and its corresponding parameters are also extracted from the measured S-parameters. The filter presents the advantages of compact size,high selectivity; low insertion loss and high out-band suppression from 5.15 GHz to 10 GHz below -31 dB. Good agreement with response of equivalent circuit, electromagnetic simulation, and measurement is demonstrated.
