ANTENNA APPARATUS AND WIRELESS COMMUNICATION DEVICE

Document Type and Number:

WIPO Patent Application WO/2024/066544

Kind Code:

A1

Abstract:

Provided are an antenna apparatus and a wireless communication device. The antenna apparatus comprises an antenna array. An antenna unit of the antenna array comprises a metal floor; a first support layer, spaced apart from one side of the metal floor; a radiation patch, arranged on the side face of the first support layer away from the metal floor; a feed network, which is arranged on the side face of the first support layer facing the metal floor and which is spaced apart from the metal floor; and a feed structure, arranged on the first support layer. The feed network supplies power to the radiation patch by means of the corresponding feed structure. The radiation patch comprises a first patch body and a first window; a vertical projection of the feed network within a plane where the radiation patch is located overlaps at least part of the first patch body or overlaps at least part of the first patch body and at least part of the first window; and at least one end of the feed network extends out of the radiation patch. In the way, the antenna apparatus can increase the layout area of the feed network, and can reduce mutual coupling when the radiation patch is close to the feed network in layout, so as to reduce influences on antenna performance, thus helping to miniaturize antenna apparatuses.
