Performance Analysis of Rectangular Patch Antenna Using Quarter Wave Feed Line and Coaxial Feed Line Methods for C- Band Radar Based Applications
Micro strip antenna has various attractive features like light weight, low cost, easy fabrication, etc. Micro strip antenna can be fed in a variety of ways. This paper is focused on the enhancement of gain of the rectangular patch antenna at 7.5GHZ for two different feeds and compares their results. The two types of feed are coaxial cable feed and quarter wave feed. Antenna design has been simulated using HFSS (High Frequency Structure Simulator) tool. Comparative study of simulated parameters like Gain, Bandwidth, Directivity and Radiation pattern for these two feeding methods have been done and presented in this paper.
