Aperture coupled microstrip antenna with different substrate thickness

Abstract

This paper is concerned on constructing, optimizing and analyzing the different thickness of substrate for aperture coupled microstrip antenna. The design is constructed with respect to 2.4GHz of centre frequency. Structures are design by using different substrate thickness ranging from 1.27mm to 2.54mm. The physical parameters are analyzed and optimized by using commercial computer simulation technology (CST) packages. The result of return loss (S 11 ), gain, voltage standing wave ratio (VSWR) and frequency for different substrate thickness will be carried out. The antenna was then to be measured by vector network analyzer (VNA) to carry out its S 11 and VSWR result. The result from simulation and measurement are compared. This antenna promised for various communication applications such as wireless and antenna application.Keywords-Microstrip patch antenna; aperture coupling; return loss (S 11 ); gain; voltage standing wave ratio (VSWR); computer simulation technology (CST); vector network analyzer (VNA)
