1. An antenna device, comprising:
an antenna array;
a beamforming circuit, connected to the antenna array, wherein the beamforming circuit is configured for controlling the antenna array to perform beamforming, wherein the beamforming circuit comprises a temporary storage circuit, wherein the temporary storage circuit comprises a first-in-first-out region, and the first-in-first-out region stores a plurality of beam indices; and
a processor, connected to the beamforming circuit, wherein the processor is configured for controlling the beamforming circuit through a first processing interface to sequentially read the plurality of beam indices by a first-in-first-out method, and setting a beam direction of the antenna array according to a read beam index, wherein the read beam index corresponds to the beam direction of the antenna array,
wherein the processor is further configured for setting a beam direction of the antenna array according to a read beam index in beam sweep time, wherein the beam sweep time, which is less than or equal to a cycle prefix time, is set in the cycle prefix time,
wherein the first processing interface is a general-purpose input/output interface.
