Characteristics of the Radiating Element of a Planar Vivaldi Antenna Array with Improved Bandwidth
Известия высших учебных заведений России: РадиоэлектроникаIntroduction. The conventional approach to extending the operating frequency band of Vivaldi antenna arrays consists in increasing the radiating element length. However, this inevitably leads to an increase in the mass of the entire array, and, therefore,
