UWB Antenna Vivaldi Based on Substrate Integrated Waveguide

摘要

A phased study of the characteristics of the printed antipodal Vivaldi antenna models based on a substrate integrated waveguide in the frequency band 18-42 GHz was carried out. It was found that both the dimensions of the aperture and the exciting segment significantly affect the gain of the antennas as well as their matching in the frequency band. Antenna models were analyzed in CST Microwave Studio. Matching characteristics and radiation patterns are presented.
