  • Publication number: 20240421491
    Abstract: A built-in antenna includes a first printed circuit board (PCB) having antenna areas arranged so that at least one antenna area is arranged at each of the corners of the first PCB. The antenna areas are spaced apart from one another, and circuit components are arranged in areas other than the antenna areas. A second PCB has first antenna patterns respectively arranged at locations corresponding to the antenna areas on the first PCB. A third PCB is vertically coupled to the first and second PCBs to electrically connect them. The second PCB includes a second antenna pattern arranged in an area other than areas in which the first antenna patterns are arranged. This increases a degree of freedom in design and improves bandwidth and efficiency by arranging each antenna in a plate-shaped structure.

  • Patent number: 12081430
    Abstract: Techniques for a hub node to, provisioned in a network site of a hub and spoke overlay network, to receive a network advertisement from the spoke, decode network routing requirements from a border gateway protocol (BGP) large community associated with the network advertisement, and store the network routing requirements in association with a route associated with the spoke. The routing requirements may indicate one or more service(s) to be applied to the packet, a trust level associated with the spoke, and/or a trust zone associated with the spoke. The hub node may receive a packet from the spoke to be transmitted to destination spoke. The hub node may then route the packet to the destination spoke, drop the packet, or send the packet to a service node configured to apply the one or more services to the packet based on the routing requirements.
