A 18-40 GHz Full Connected Vivaldi Antenna Array

In this work, a full connected single polarized Vivaldi array is realized to provide for the very first time a whole K band operation, from 18 to 40 GHz single polarization. The steering sector is measured to be 30° on azimuth plane. The solution investigates some industrialization issues that arise when operating in K band and represents a preliminary step for a dual polarized architecture.
