In this paper, the author proposes 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 1.65GHz-1.8GHz, 3.45GHz-4.4GHz and 7GHz-7.55GHz respectively. The proposed antenna provides notches at the frequencies of 1.75GHz, 3.85GHz and 7.25GHz. The simulated results of the proposed antenna exhibit good transmission coefficient, stable gain and radiation pattern at the operating frequencies.
