  • Patent number: 10680345
    Abstract: An antenna for dual-band or wide-band communication link. The antenna includes a patch array, arranged above a top ground plane, that includes one or more panels, each panel included one or more patch subarrays, and each patch subarray includes single patch elements made from metal. Each patch element includes: a flat rectangular radiation surface element into which a rectangular cutout is formed; an RF power feed point having a cylindrical shape that makes contact to the bottom side of the radiation surface element and feeds through a hole formed in the top ground plane for connection to the RF power; and a structural post having a cylindrical shape that contacts, at one end, the bottom side of the radiation surface element at a region of the radiation surface element where electric surface current is substantially smaller than any other region, and contacts the top ground plane at a second end.
