ANALYSIS OF PATCH ANTENNA FOR PARAMETER ENHANCEMENT AT 1.911GHZ

In this paper work, A patch antenna and our proposed metamaterial patch antenna are simulated and compared. A rectangular microstrip patch antenna along with the innovative metamaterial structure is proposed at a height of 3.2mm from the ground plane. This work is mainly focused on increasing the potential parameters of microstrip patch antennas and analyzing the dual band operation of proposed antenna.This structure produces a better performance compared to simple RMPA. The implementation of the metamaterial as the substrate in a rectangular microstrip patch antenna produces high value of return loss. Rectangular Microstrip Patch antenna loaded with metamaterial (MTM) is proposed for better improvement in the impedance bandwidth and reduction in the return loss at operating frequency 1.911 GHz. The proposed antenna is designed at a height 3.2 mm from the ground plane. At 1.911 GHz, the bandwidth is increased up to 27.2 MHz in comparison to RMPA alone of bandwidth 6.5 MHz. The Return loss of proposed antenna is reduced by -19.15dB. Microstrip Patch antenna has advantages than other antenna is lightweight, inexpensive, easy to fabricate and achieve radiation characteristics with higher return loss. CST MICROWAVE STUDIO is used to design the metamaterial based rectangular microstrip patch antenna.
