Abstract :
Along this document, the reconfigurability possibilities of a dual band microstrip patch antenna based on short-circuited SRR is studied. Since the antenna presents a narrow bandwidth, reconfigurability techniques has been implemented to extend the effective bandwidth of the device. The proposed antenna has a multilayer configuration where the feeding line and the radiating layer are located at different levels. A previous study by using lumped elements has been carried out and taking into account these results, the final reconfigurable version has been implemented by using varactor diodes.
