US 12,712,263 B2 · Antenna phase control method and device

Abstract

An antenna phase control method is applied to an antenna phase control device, the antenna disposed on a moving carrier to communicate with a satellite. The method includes obtaining an initial phase of the antenna, obtaining an instant rotation information of a steering wheel of the moving carrier and speed information of the moving carrier, calculating a compensation phase of the antenna according to the instant rotation information and the speed information, and adjusting the initial phase of the antenna according to the compensation phase. The present disclosure also provides an antenna phase control device. The present disclosure can calculate the antenna phase according to the direction information and the speed information of the moving carrier, so as to dynamically adjust the radiation direction of the antenna.
