Claim of US Patent No. 10,483,640

1. An omnidirectional ultra-wideband antenna, comprising:an electrically conductive conical surface having a vertex end and a base end;
a supplemental radiating element having a first portion and a second portion, the first portion extending from the base end of the electrically conductive conical surface, the first portion being positioned between the base end of the electrically conductive conical surface and the second portion, the first portion being cylindrical and the second portion being frustoconical;
a ground plane plate having opposed first and second surfaces and including a peripheral edge, the vertex end of the electrically conductive conical surface being positioned adjacent to, and spaced apart from, the first surface of the ground plane plate;
at least one electrically conductive rod having opposed first and second ends, the first end of the at least one electrically conductive rod being secured to the second portion of the supplemental radiating element, the second end of the at least one electrically conductive rod being connected to the first surface of the ground plane plate at the peripheral edge;
a coaxial cable having a center conductor and an outer conductor, the center conductor being in electrical communication with the vertex end of the electrically conductive conical surface, and the outer conductor being in electrical communication with the ground plane plate; and
a third radiating element mounted inside the electrically conductive conical surface, wherein the third radiating element is conical and includes a vertex end positioned adjacent the vertex end of the electrically conductive conical surface.
