This figures show the antenna structure we designed. An ESPAR antenna consists of an active element with one RF chain connected to the center and passive elements with variable reactance around it. In the antenna, the beam pattern is changed according to the reactance value of each passive element. In order to perform beamforming in a desired direction, after designing an antenna, it is necessary to identify a beam pattern generated by applying each reactance set. | |
