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.

Abstract: An antenna apparatus and a control method are provided. The antenna apparatus includes a first antenna, a second antenna, and a movable mechanism. The first antenna is operated on a first frequency band. The second antenna surrounds the first antenna and is operated on a second frequency band.

Abstract: An antenna includes a high band configuration, a low band configuration, and two signal integration modules. The high band configuration includes two three-dimensional feed-ins and a resonator. The three-dimensional feed-ins respectively receive first band signals perpendicular to each other. The resonator is disposed above the three-dimensional feed-ins and is coupled with the three-dimensional feed-ins. The orthogonal projection of the resonator at least partially overlaps with the three-dimensional feed-ins. The low band configuration includes two dipole feed-ins. The dipole feed-ins is disposed above the high band configuration and respectively receives second band signals perpendicular to each other. The signal integration modules are electrically connected to the high band configuration and the low band configuration and integrate the first band signals and the second band signals into broadband signals.
