Enhancement of the Rectangular Microstrip Patch Antenna Performance Using New 'E' Shaped Metamaterial Structure at 2.684 GHz
The authors present microstrip patch antenna incorporated with left-handed metamaterial at 2.684GHz. The proposed antenna uses metamaterial structure in the height of 1.6mm from the ground plane. This paper shows the comparison between the microstrip patch antenna using alone and loaded with metamaterial structure with the enhancement in antenna gain and reduction in return loss at the same resonant frequency. By use of this combination it has been seen that there is a step up of return loss of around 6dB.
