Abstract: A server system receives a group operation request transmitted by a client. The group operation request is generated by the client in response to a trigger operation of a target group chat function, and includes a target identity and a target group chat function identifier. The server system determines a target group chat function use permission corresponding to the target identity. In accordance with a determination, based on the target group chat function use permission and the target group chat function identifier, that a user corresponding to the target identity has a permission to use the target group chat function, the server system transmits group operation result information to the client.

Abstract: A patch antenna includes a plurality of patch units, a first feeding branch, and a second feeding branch. The plurality of patch units is symmetric relative to a virtual symmetry axis. The plurality of patch units is arranged at intervals. A gap is formed between adjacent patch units, and the adjacent patch units are coupled through the gap. The first feeding branch and the second feeding branch are symmetric relative to the symmetry axis, and each of the first feeding branch and the second feeding branch is electrically connected to at least one patch unit of the plurality of patch units. The first feeding branch is configured for a first polarization of the patch antenna, and the second feeding branch is configured for a second polarization of the patch antenna.
