Ultra-Wideband High-Gain Transmitarray Antenna : For practical applications of transmitarray antennas

摘要

In this paper, demonstration of a dual-polarized ultra-wideband transmitarray antenna with Vivaldi elements is presented. The aperture features a physical area of 1.1×0.35m^{2, providing a peak gain of 26 ~ 36dBi within a frequency band from 5 to 16GHz. The experimental results show that the transmitarray antenna has stable radiation performances within the operating band, validating the feasibility of the design.}
