First Claim
1. A multi-feed dipole antenna comprising:
- a top tube;
a bottom tube;
a top pin conductively connected to said top tube;
a bottom pin conductively connected to said bottom tube;
a center tube insulatively coupled with said top tube and said bottom tube and positioned coaxially between said top tube and said bottom tube; and
,wherein said multi-feed dipole antenna is fed from both said top tube and said bottom tube via said top pin and said bottom pin respectively.

Abstract
A multi-feed dipole antenna and method. Provides a volumetrically efficient antenna with wide radiation pattern bandwidth and wide impedance bandwidth that are relatively independent. Driving the antenna at multiple locations provides for a half wavelength dipole antenna with a wider frequency range than any other known fat dipole of similar volume. The apparatus is constructed from brass or any other suitable metal without requiring dielectric loading and without requiring direct coupling on the outside of the tubes. The apparatus utilizes a parasitic center tube with two end tubes that are driven by a collinearly mounted metal rod that is driven from the midpoint. Insulators hold the parasitic tube to the end tubes. The parasitic tube allows for induced currents to flow on the surface of the tube which allow for operation of the dipole over a wide frequency range.
