Abstract :
A new miniaturize proximity coupled microstrip antenna with defected ground plane is presented in this paper. The proposed antenna operates in the 2.45 GHz ISM band, which is suitable for WLAN application. By introducing the circular ring slot as a defected ground plane, a reduction size of radiating element is obtained. This circular slot ring results in a 45% reduction in the area of the patch element, and improves the proposed antenna efficiency by 85%. The evolution of the proposed design has been discussed clearly in this paper. Both simulation and measurement results show comparable values in terms of reflection coefficient performance.
