Evaluation & Comparison between Plus Sign Slotted and U-shaped Microstrip antennas for Wi-MAX application using IE3D

Abstract

In this paper, a slotted patch antenna of Microstrip antenna (MSA) type has been put forward. The enrichment in gain is realized by cutting slots of suitable dimensions in the rectangular patch using the technique of probe feed. Optimum feed providing the required outcome is found. Simulation of the two projected antennas had been carried out by means of IE3D software. Performance assessment would be grounded on altering the patch dimensions, the acquired results are compared especially in gain, the efficiency of the antenna, the pattern of radiation, VSWR, and return loss with a U-shaped patch antenna.
