Design and analysis of 5.2 GHz rectangular microstrip patch array antenna using split ring resonator

Now a days microstrip patch antennas are heavily used in the field of communication for their compact size, low cost, flexibility and efficiency. Different shapes and sizes of patch antennas are available in the market. In this paper effect of split ring resonator on rectangular patch array antenna of 5.2 GHz is discussed. It is seen that the multiple frequencies with different gain, return loss, VSWR are obtained after introducing array geometry with split ring resonator in the Rectangular Patch Antenna. The gain for rectangular patch antenna at 5.2 GHz is 4.39 dB. The gain is 5 DB for rectangular patch array. Gain improved to 8 dB for Rectangular patch array with Split Ring Resonator. Gain improves by 45.12% and bandwidth improves by 56.25%. The FR4 Epoxy substrate is used to design the antenna with HFSS software.
