Matching technique for microstrip patch antenna using GCPW feed

Abstract

A new method for feeding Microstrip patch antenna with inset feed using the concept of coplanar waveguide feed line has been proposed and investigated for a printed antenna at X-Band frequency of 10GHz. The proposed antenna overcomes the problem of variations in resonant frequency with inset width and provides improved gain. The characteristics of the antenna are determined in terms of Return loss, VSWR, gain, radiation pattern etc. The measured and simulated results presented are found to be in good agreement.
