A narrow band micro strip patch antenna with four cocentric circular Rings” shaped metamaterial cover is
proposed at a height of 3.2mm from the ground plane. The antenna along with the proposed metamaterial cover is
designed to resonate at 2.31GHz frequency (in S-Band). Proposed metamaterial cover significantly reduces the return
loss and increases the gain of the antenna in comparison to conventional rectangular microstrip patch antenna alone.
After that, the antenna design with the planned metamaterial cover, due to the cover the antenna is start resonating at
1.548 GHz frequency. For designing an antenna at resonating frequency 1.548 GHz is required more space than the
design. In the design, the antenna design along with the metamaterial cover which has some special properties so the
antenna is minimize in the size and also reduce the return loss and increases the efficiency of the antenna. The purpose of
this work is to design a compact and efficient antenna with metamaterial cover.
