Abstract :
A zero-index metamaterial based high-gain microstrip antenna for IEEE 802.11a WLAN applications is presented. A three layer superstrate with unit-cell periodicity of 6 × 6 was designed and suspended above a microstrip patch antenna at an optimum position for best performance. The broadside gain enhancement of the proposed antenna is observed to be 5.8 dB with variations less than 2dB throughout the operating band.
