Design of Compact Microstrip Patch Antenna Using NZIM Lens for Increased Gain
Abstract:
The paper presents a Microstrip Patch Antenna (MPA) for WLAN application using a superstrate structure that consists of an array of a 7X7 metamaterial unit cells. An improved broadside gain is obtained with the proposed structure. To obtain the proposed metamaterial unit cell, an extra metal strip is added to the conventional mirrored S like structure. The confirmation of the near-zero index behavior is carried out using the unit cell analysis and parameter extraction using periodic boundary condition. It also confirms the significant reduction in the unit cell foot print. The enhancement of gain using the NZIM (Near Zero Index Metamaterial) lens can be confirmed by simulation results. Similarly there is a reduction of half power beam width in both E-plane and H-plane by 200.
