Design and Analysis of High Gain Proximity Feed Microstrip Patch Antenna for Wi-Fi Applications

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.
