A wideband antipodal Vivaldi antenna has been designed and optimized. A slight improvement is obtained by employing multiple metalense based on circular split-ring resonators to maximize the antenna gain with the maximum bandwidth. The designed antennas have been fabricated and characterized, showing good agreement with simulations. The maximum measured gain is G = 12 dB, and the −10 dB bandwidth is from f = 3 GHz to f = 13 GHz.

Abstract
A wideband antipodal Vivaldi antenna has been designed and optimized. A slight improvement is obtained by employing multiple metalense based on circular split-ring resonators to maximize the antenna gain with the maximum bandwidth. The designed antennas have been fabricated and characterized, showing good agreement with simulations. The maximum measured gain is G = 12 dB, and the −10 dB bandwidth is from f = 3 GHz to f = 13 GHz.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
