Effect of Slot Rotation on Rectangular Slot based Microstrip Patch Antenna

Abstract

In this paper, a rectangular slot based microstrip patch antenna is designed and their analysis is done to evaluate their effect due to rotation of slot for wireless communication applications. The proposed antenna is suitable for numerous applications such as bluetooth, wi-fi, WLAN, and other mobile communication systems depending on the angle of rotation. The results showed sufficient isolation among different resonant frequencies with improvement in gain and directivity. The results obtained had showed better improvement in the return loss and radiation pattern in comparison to the other existing slot antennas.
