A novel reconfigurable active feedback antenna for WiMAX/WLAN applications is presented. By using an H-shaped radiating patch with a pair of C-shaped slots in the active feedback antenna, two new resonances can be achieved. Also, the proposed radiating patch has a major advantage in providing tighter capacitive coupling to the line in comparison to known radiating patch. In order to generate DC isolation in the RF path, we use a pair of gap distances in the microstrip loop. Also, by using the [S] parameters of the active element, a novel design of the microwave oscillator is performed. Simulated and experimental results obtained for this antenna show that the proposed Active Integrated Antenna (AIA) has a good return loss and radiation behavior within the WiMAX/WLAN frequency range.
