Abstract

This paper presents an ultra-wideband one-dimensional plane wave generator antenna array. Tightly coupled Vivaldi antennas is used with active VSWR nearly lower than 2 across the frequency band from 1 to 7 GHz. A new plane wave excitation optimization algorithm using full wave simulation transfer matrix is proposed and compared with the traditional ideal point source plane wave optimization algorithm. One-dimensional quasi-plane waves with amplitude vibrations within ±0.75dB and phase vibrations within ±7.5° ranged from 1GHz to 6GHz is realized by carefully optimizing the feed amplitude and phase of the tightly coupled array element.
