Design and development of microstrip interdigital filter

Abstract

A microwave filter is a two port network which is used to control the frequency response. This thesis presents the interdigital filter based on Chebyshev bandpass filter. The model is taken from lumped elements using Advanced Design System (ADS) simulation method and implements on RO4003C substrate with 0.508 mm thickness and dielectric constant 3.38. This interdigital filter is designed and developed a microstrip with order of 3. It is designed based on the concept of microstrip parallel coupled line at frequency range from 2 to 4 GHz.
