Low profile bicone antenna
First Claim
1. An antenna, comprising:
- a first radiating element having a first substantially conical radiating surface;
a second radiating element having a second substantially conical radiating surface, wherein the first and second radiating surfaces are substantially aligned coaxially, and wherein the first and second radiating elements extend in opposing directions on opposing sides of a signal launching region;
a signal feed extending through the first radiating element and positioning a signal launch point between the first and second radiating elements in the signal launching region proximate vertices of the first and second radiating surfaces;
a base; and
a shroud;
wherein the first and second radiating elements have first and second included angles, respectively, that are each no less than about 75 degrees;
wherein the base is directly coupled to the first radiating element and the shroud; and
wherein the shroud envelopes the first and second radiating elements.

Abstract
An antenna that includes, in at least one embodiment, first and second radiating elements each having a substantially conical radiating surface. Each radiating surface may be substantially linearly conical or nonlinearly conical. The radiating surfaces are substantially aligned coaxially, and the radiating elements are positioned on opposing sides of a signal launching region, extending in opposing directions from the signal launching region. A signal feed extends through the first radiating element, thereby positioning a signal launch point between the first and second radiating elements in the signal launching region proximate vertices of the first and second radiating surfaces. The first and second radiating elements have first and second included angles, respectively, that are each no less than about 40 degrees.

10. A method, comprising:
-
coupling a signal cable to a feedthrough connector, wherein the signal cable includes an inner conductor, an insulator forming an annulus substantially coaxially around the inner conductor, and an outer conductor forming an annulus substantially coaxially around the insulator; inserting the signal cable through a first radiating element, wherein the first radiating element includes a substantially conical radiating surface having a first included angle of no less than about 75 degrees; coupling the outer conductor to the first radiating element proximate a first vertex of the first radiating surface; coupling the inner conductor to a second vertex of a second radiating surface of a second radiating element, wherein the second radiating surface is substantially conical and has a second included angle of no less than about 75 degrees; after coupling the inner conductor to the second radiating element, coupling a base to the feedthrough connector and the first radiating element such that rotation of the base relative to either of the feedthrough connector and the first radiating element is substantially prevented; and after coupling the base to the feedthrough connector and the first radiating element, coupling a shroud to the base, wherein the shroud and base collectively enclose the first and second radiating elements. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
