Abstract: An antenna system with a switchable horizontal half-power beamwidth includes: a ground plane module including rows of patch groups that jointly form a ground plane; an antenna unit spaced apart from the ground plane by an interval; and a control module that can receive at least one beam control message. Each two adjacent rows of the patch groups are provided therebetween with at least one switching unit. The control module can bring each of the at least one switching unit to be turned on or turned off according to contents of the at least one beam control message, so as to adjust the electrical properties of the ground plane and change the horizontal half-power beamwidth of the antenna unit. Accordingly, the antenna system has a relatively low-profile spatial property, and requires no extra mechanism design for horizontal half-power beamwidth adjustment and switching based on practical needs.

Abstract: An easily mountable device bracket assembly includes a first bracket having a side that can be provided with at least one mounting member, a second bracket, and a third bracket having a side that can be fixed to a device housing and at least one bent portion having an inner wall spaced apart from an outer wall of the third bracket to form a slide groove. At least one gap formed by the mounting member and the side of the first bracket forms another slide groove. The second bracket can extend into the another slide groove in a connecting direction to be connected with the first bracket. When the device mounted with the third bracket is placed into an open rack or rack-type cabinet, the slide groove is in contact with the first bracket, and the third bracket is connected to the first bracket slidingly along the connecting direction.

Abstract: A computing device includes a processing unit, a memory unit, a NIC that is for receiving a packet, and a network virtualization platform accommodating a plurality of virtual network applications. The NIC, the processing unit and the memory unit are collectively defined as a hardware layer for the network virtualization platform to operate thereon. The network virtualization platform includes a virtual network layer having a UPF plugin installed therewith. The UPF plugin performs rule matching according to a packet header of the packet, and determines which one of the following steps is to be performed: offloading the packet to one of the virtual network applications in the application layer for the virtual network application to provide services; and re-packaging the packet and forwarding the packet to the another computing device.

Abstract: A microstrip antenna includes a substrate, a feedline, an impedance matching structure, and a patch radiator, wherein the substrate has a surface. The feedline is disposed on the surface and extends along a first axial direction. The impedance matching structure is disposed on the surface and has a first end and a second end in the first axial direction, wherein the first end is connected to the feedline. The impedance matching structure has a stepped impedance change. The patch radiator is disposed on the surface, wherein the patch radiator and the second end of the impedance matching structure are adjacent and spaced by a distance in the first axial direction, and the second end of the impedance matching structure is coupled with the patch radiator through the distance. Therefore, a bandwidth of the microstrip antenna could be increased.

Abstract: A radome is provided for covering an antenna. The radome is disposed in a transmission path of a radiation from the antenna and modifies a radiation pattern of the antenna when the radiation from the antenna penetrates therethrough. The radome has a first surface and a second surface opposite to the first surface and facing the antenna, and includes a plurality of through holes penetrating through the first and second surfaces and having first and second openings on the first and second surfaces, respectively. The first openings of the through holes are allocated in at least a central area of the first surface, an inner annular area of the first surface surrounding the central area, and/or an outer annular area of the first surface surrounding the inner annular area in a manner that an area-averaged permittivity is increasing radially outwards from the central area toward the outer annular area.
