Strengthening means for a dipole whip antenna

摘要

A dipole antenna comprises a hollow dielectric whip, a coaxial center feed extending therethrough, and a pair of conductive dipole elements comprising an upper element and a lower element. The dipole antenna further comprises an upper element lead connecting the upper element to a first portion of the coaxial center feed at a feed point and a lower element lead connecting the lower element to a second portion of the coaxial center feed at the feed point. The dipole antenna further comprises a feed point strengthening means to mechanically strengthen the feed point against disconnection when the whip is impacted. Additionally, the dipole antenna may be a dual dipole antenna.

1. A dipole antenna comprising:
a hollow dielectric whip, a coaxial center feed extending through the hollow dielectric whip, a first pair of conductive dipole elements on the hollow dielectric whip comprising a first upper element and a first lower element, a first upper element lead connecting the first upper element to a first portion of the coaxial center feed at the at least one first feed point, a first lower element lead connecting the first lower element to a second portion of the coaxial center feed at the at least one first feed point, wherein the at least one first feed point is disposed on a first axis of a first cavity in the hollow dielectric whip, a second pair of conductive dipole elements comprising a second upper element and a second lower element, a second upper element lead connecting the second upper element to the first portion of the coaxial center feed at a second feed point, and a second lower element lead connecting the second lower element to the second portion of the coaxial center feed at the second feed point, wherein the second feed point is disposed on a second axis of a second cavity, wherein the first cavity and second cavity each has a central axis parallel to the length of the hollow dielectric whip, and the first and second axes are oriented perpendicular to one another.
