Computer Aided Design of U-Shaped Rectangular Patch Microstrip Antenna For Base Station Antennas of 900 MHz System

摘要

In this paper, we will present a new computer aided design for microstrip antenna element with U-shaped rectangular patch for sectored coverage of base station antennas of 900 MHz system is proposed for improving antenna performance in terms of gain and bandwidth. A dielectric cover is used to protect the patch against environmental hazard. We have present also another solution using air dielectric as a superstrate, which is a much lighter and cheaper solution. A Green's function based mixed potential integral equation in conjunction with the method of moments is implemented for the formulation and analysis of the microstrip structures. For this contribution, design aspects and the obtained simulated results for the proposed antenna are presented.
