Abstract

In this work a simplified and accurate mathematical formula is derived to predict the reduced dimension of the microstrip circuit by using applicable etching geometry on plane of microstrip circuit such as DGS/DMS that will affect the resonance frequency of microstrip circuit in desired direction due to increment of slow wave effect. Here we developed proportional formula of defect which is verified successfully by applying to network implemented with an open circuit and for microstrip patch antennas, phase shifter.
