Comparative Analysis of Microstrip Rectangular Patch Antenna with Different Feeding Techniques using HFSS

Microstrip Antenna consists of a very thin patch placed above ground plane. Purpose of using microstrip patch antenna is to serve maximum number of applications with light weight and low cost antenna considering the easy manufacturing. Patch mounted on substrate can be of any shape and size though every shape and size will make a difference in efficiency of antenna, currently E Patch and U Patch are considered to serve wide area of applications in an optimized way. In this paper we have designed and simulated the rectangular patch antenna and compared the different characteristic parameters of simulated antennas by using the feeding techniques like microstrip line feeding and coaxial feed technique.
