The modern communication systems need development in antennas which have large bandwidth and low profile. Profile is the physical size of the antenna and it should be as small as possible for easy installation and operation. The paper deals with design aspects of square microstrip patch antenna with proximity feed and its properties. In this paper, simulations are carried out on C-band square microstrip patch antenna that suits Wi-Fi and bluetooth applications. With the adjusted parameters, the designed antenna exhibits maximum gain of 7 dBi and return loss 40 dB at center frequency 5 GHz. Desired patch antenna design was simulated using ANSYS HFSS software. The substrate material used for designing of microstrip patch antenna is RT Duroid 5880 and the thickness of the substrate is 1.6 mm.

 
 

The wireless communication is not possible without antennas. Some of the antennas are: parabolic reflectors, horn antennas, helical antennas, log periodic antennas, monopole antennas, dipole antennas, loop antennas, folded dipole antennas, yagi-uda antennas and finally patch antennas Balanis (2005). Each antenna has its own design and advantage. Microstrip antennas concept was first proposed by Deschamps in 1953 and first radiator was developed by Bob Munson in 1971. Microstrip patch antenna design is very easy compared to other antennas and operation is also simple. The basic advantage in microstrip patch antenna is low profile. The microstrip patch antenna can be easily integrated with other microwave circuits Sainati (1996). Generally, microstrip patch antenna consists of a radiating patch and ground plate on the dielectric substrate. The radiating patch and feed lines are photo-etched on the dielectric substrate.
