Size reduction of Rectangular Microstrip Patch Antenna incorporated with “INTERCONNECTED FRAMED SHAPED” Metamaterial structure for WLAN applications

This work deals with the analysis and simulation of a Rectangular Patch Antenna supported by a “INTERCONNECTED FRAMED SHAPED” Metamaterial structure at a height of 3.2mm from the ground plane and also investigates the potential properties of the proposed antenna. The proposed Antenna is designed at a operating resonant frequency of 4.65GHz to meet WLAN applications. All the simulation work is done using CST-MWS (Computer Simulation Technology Software). MathCAD-15 Software is used to prove that the proposed design possesses Double-Negative Metamaterial properties. By incorporating the proposed design with the patch antenna at a height of 3.2mm from the ground plane, the patch antenna size is found to be reduced by 30% (area wise). The potential properties like returnloss & bandwidth of the proposed antenna increases to a great extent in comparision to the Rectangular Patch Antenna alone.
