Abstract :
A novel microelectromechanical systems (MEMS) actuator for patch antenna reconfiguration is presented for the first time. A key feature is the capability of multi-band operation without greatly increasing the antenna element dimensions. Experimental results demonstrate that the center frequency can be reconfigured from few hundred MHz to few GHz away from the nominal operating frequency.
