High-gain triple-band reconfigurable Vivaldi antenna

Comunicació presentada a: 2014 IEEE-APS Topical Conference on Antennas and Propagation in Wireless Communications (APWC), celebrada del 3 al 9 d'agost de 2014 a Palm Beach, Les Antilles Neerlandeses.A frequency agile Vivaldi antenna whose operating frequency band can be switched is pro- posed. High-performance radio-frequency micro- electromechanical system (RF-MEMS) switches al- low tuning of the operational band between 2.0 GHz, 3.7 GHz and 5.2 GHz. The average gains of the an- tenna for the low, mid and high bands are 8.5 dBi, 12.5 dBi and 13.7 dBi, respectively. This recon- figurable antenna others improved performance over multiple, wideband and multiband antennas without increases in cost and size.This work has been undertaken as part of EP-SRC PhD Case Award, grant reference number: EP/G037264/1, in conjunction with L-3 TRL Technology
