Modeling and Simulation of a Micro strip Antenna in Annular Geometry

Abstract

Micro strip antenna has been widely developed over time due to its flexibility and easier todesign. The aim of this work is the simulation of an Annular Micro strip Patch antenna using CST software(Computer Simulation Technology) in order to know its performance (Gain, the reflection parameter S11,directivity, efficiency…). Adding slots to the initial patch was determined to improve the main factors ofthese characteristics.
