Abstract
An antenna structure is provided, which includes a substrate, a ground layer, a multi-branch circuit, and multiple antenna elements. The substrate includes a first surface and a second surface. The ground layer is disposed between the first surface and the second surface. The multi-branch circuit is disposed on the first surface, wherein the multi-branch circuit includes a signal feeding terminal and multiple signal output terminals, wherein multiple feeding branches are formed between the signal feeding terminal and the multiple signal output terminals. The multiple antenna elements is disposed on the second surface, wherein the multiple antenna elements are connected to the multiple signal output terminals through respective via holes, and are configured for beamforming, wherein a length difference between path lengths of the feed branches of two adjacent antenna elements in a horizontal direction is configured for controlling a beam angle of the multiple antenna elements.
