A Triple-Band Monopole Microstrip Patch Antenna for Wireless Communications

Priti Rai, Kalyan Mondal

In this article a triple-band monopole microstrip patch antenna is designed and analyzed. The proposed antenna consists of T shaped microstrip patch and ground plane with rectangular slits on the patch and ground plane respectively. The proposed antenna provides a triple-band of bandwidth 1.65 GHz-1.8 GHz, 3.45 GHz-4.4 GHz and 7GHz-7.55 GHz respectively. The proposed antenna provides notches at the frequencies of 1.75 GHz, 3.85 GHz and 7.25 GHz. The simulated results of the proposed antenna exhibit good transmission coefficient, stable gain and radiation pattern at the operating frequencies. The proposed monopole antenna is very popular in wireless communication system for multiband applications. The proposed antenna is simulated using Ansoft designer software.
