Amelioration of rectangular microstrip patch antenna characterstics by incorporating it with double-Negative left-handed inspired metamaterial in L-band

With the numerous increases in the use of microwave frequencies in communication applications, certain antenna potential characteristics should be an integral part of the design process. For example, GPS, WLAN are all applications that share common potential characteristics requirement in their antenna. A “FRAMED SQUARE RINGS” double negative inspired metamaterial structure was introduced as a cover to the rectangular microstrip patch antenna at a height of 3.2 mm from the ground plane, operating at 1.95 GHz. The results showed that the proposed metamaterial cover, effectively improves the patch antenna’s gain and bandwidth. The complex permittivity and permeability of the proposed structure has been extracted by Nicolson-Ross-Weir (NRW) approach. The outcomes of this work open the possibility to use the proposed structure as a miniaturized and flexible antenna in L-Band for wireless communication applications.
