Abstract :
A single layer dual-polarized.microstrip patch antenna with dual port is designed, simulated and analyzed. The two ports are provided with a 1800 phase shift and designed to operate in the C-band with a solution frequency at 4GHz. The edges of the patch are etched which helps to improve the polarization of the designed antenna. The inset feed is the feeding technique used for the design of the dual-polarized antenna which provides a gain of about 8.5dB. This paper describes the parameters of the dual-polarized patch antenna like VSWR, Radiation Pattern, Axial Ratio and Return Loss are simulated and results are recorded. The proposed antenna works for the single narrow band frequency having a return loss lesser than -10dB and finds its application in satellite communications and weather RADAR.
