This paper represents the Designing of 2.4 GHZ H shaped microstrip patch antenna using electromagnetic simulation software i.e. Ansoft hfss. As the rectangular microstrip patch antenna is suffering from the narrow bandwidth hence Instead rectangular patch H shaped is used to get broad bandwidth. The model designed in Ansoft hfss v.13 and it is simulated. Simulation result includes the various parameters of antenna such as Return loss, VSWR, gain, radiation pattern, Axial ratio
