Abstract
A frequency agile Vivaldi antenna whose operating frequency band can be switched is proposed. High-performance radio-frequency micro-electromechanical system (RF-MEMS) switches allow tuning of the operational band between 2.0 GHz, 3.7 GHz and 5.2 GHz. The average gains of the antenna for the low, mid and high bands are 8.5 dBi, 12.5 dBi and 13.7 dBi, respectively. This reconfigurable antenna offers improved performance over multiple, wideband and multiband antennas without increases in cost and size.
