In this paper a design of proximity coupled equilateral triangular microstrip antenna with diamond shape slot on the radiating patch is studied. The antenna consists of two layers with glass epoxy material of thickness (h) 0.32cm each forming total thickness of 0.64cm. The proposed diamond shape slot loaded antenna resonates at two different frequencies 2.95GHz and 5.91GHz with bandwidth of 8.87% and 11.05% respectively with compared to that of conventional microstrip antenna which resonates at 3.07GHz with bandwidth of 9.15%. These antennas are simulated by using Ansoft HFSS electromagnetic simulation software. The antenna parameters such as return loss, bandwidth and radiation pattern are discussed and presented.
