  • Antenna apparatus, communication apparatus and steering adjustment method thereof
    Patent number: 11955721
    Abstract: An antenna apparatus, a communication apparatus, and a steering adjustment method thereof are provided. The antenna apparatus includes an antenna structure. The antenna structure includes an antenna unit. The antenna unit includes i feeding ports, where i is a positive integer larger than 2. A vector of each of the feeding ports is controlled independently. In the steering adjustment method, a designated direction is determined, where the designated direction corresponds to beam directionality of the antenna structure. In addition, the vectors of the feeding ports of the antenna unit are configured according to the designated direction. Accordingly, the antenna size can be reduced, and beam steering in multiple directions would be achieved.
