Abstract: An antenna structure, a circuit board with an antenna structure, and a communications device. The antenna structure includes a signal reference ground, a first radiation patch, a second radiation patch, and at least one feed probe. The feed probe is located between the first radiation patch and the ground. Each feed probe includes a first end and a second end. A projection position of the first end on a plane of the signal reference ground is outside a projection area of the first radiation patch on the plane of the signal reference ground is located, and a projection position of the second end on the plane of the signal reference ground is inside the projection area of the first radiation patch on the plane of the signal reference ground. The second end is electrically connected to the signal reference ground.

Abstract: Embodiments of the present disclosure disclose a method and an apparatus for handling network congestion, and a system. The method includes: obtaining a transmitted data volume of a flow, and identifying a predictable flow and a non-predictable flow in the flow; collecting statistics about total data transmission volumes of the predictable flow and the non-predictable flow; obtaining a congestion transmission model of the predictable flow, and solving the congestion transmission model to obtain a scheduling policy for the predictable flow; and allocating bandwidths to the predictable flow and the non-predictable flow to obtain a bandwidth allocation result, and sending the bandwidth allocation result and the scheduling policy to the host, so that the host executes the scheduling policy in a scheduling period. This can prevent congestion in advance and reduce a delay of a delay-sensitive flow, and is applicable to a large data center.

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.
