Design of a novel patch antenna with enhanced gain and side lobe reduction

Abstract EN

The design of an efficient and directive small size antenna, for modern wireless applications, is a major challenge.

This paper introduces the design and simulation of new method to enhance the gain and side lobe reduction that improve the performance of a conventional microstrip patch antenna.

In this work three models were discussed and analyzed.

The first model consists of a reference patch antenna plus superstrate-1 of different thickness.

Modification of this model by adding square copper ring represents the second model.

In the third model a second superstrate on the top of the square copper ring was added.

Simulation results illustrate that the first model gives a small enhancement for the gain and side lobe reduction, only gain enhancement was obtained in the second model and greater enhancement was achieved for the performance of the patch antenna in the third model.
