Abstract :
A narrow band micro strip patch antenna with "Pentagonal Rings" shaped metamaterial cover is proposed and analyzed 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 directivity of the antenna in comparison to rectangular micro strip patch antenna alone. The proposed antenna is suitable for application requiring low bandwidth space and reduced return loss, at 2.31GHz frequency. The scope of this paper is to design and simulate the proposed artificial structure with simultaneous negative permittivity and permeability or the so-called LH MTM. Nicolson-Ross-Weir approach has been used for verifying the double-negative properties of the proposed metamaterial cover.
