In this paper, a tri-band H-shaped rectangular microstrip patch antenna is presented for L, C and X-band applications. The proposed antenna has symmetrical properties and operating in a tri-band of frequency 2.4GHz. In this paper, H-shaped patch antenna is designed on a 1.56mm thick Rogers TMM 4 (tm) substrate with a relative permittivity of 4.5 and achieve a gain of 6.52dB. The simulation process has been done using HFSS v12.1 (High Frequency Structural Simulator). The key parameters like Return loss, VSWR, gain are simulated, analyzed and optimized using HFSS v12.1.
