In this work, an antipodal Vivaldi antenna optimized with different metalenses for wideband applications is designed. This light-weighted antenna is wideband and exhibits good gain in the whole bandwidth. The employment of metalenses with variable metamaterials dimensions allows to increase maximum gain of about ?G = 2 dB in the frequency band f = 7 - 10 GHz, without reducing the working bandwidth of the antenna. Prototypes have been fabricated and characterized, showing good agreements with simulations.

Abstract
In this work, an antipodal Vivaldi antenna optimized with different metalenses for wideband applications is designed. This light-weighted antenna is wideband and exhibits good gain in the whole bandwidth. The employment of metalenses with variable metamaterials dimensions allows to increase maximum gain of about ?G = 2 dB in the frequency band f = 7 - 10 GHz, without reducing the working bandwidth of the antenna. Prototypes have been fabricated and characterized, showing good agreements with simulations.File in questo prodotto:
