Abstract :
A Gunn diode loaded stacked circular patch antenna is proposed and analyzed. It is found and threshold voltage of Gunn diode controls the performance of the antenna. Various tunable frequency bands are obtained by selecting suitable bias voltage while antenna topology remains unchanged. Antenna properties like return loss, in impedance, voltage standing-wave ratio (VSWR), bandwidth, etc., are calculated with the proposed model.
