Abstract:
1. A sleeve dipole antenna, comprising: a first hollow conductive tube forming a first dipole element of the sleeve dipole antenna; a second hollow conductive tube forming a second dipole element of the sleeve dipole antenna, wherein the first and second hollow conductive tubes are coupled end-to-end and separated by a dielectric support; a transmission feed line routed through the second hollow conductive tube along a longitudinal axis of the sleeve dipole antenna and coupled to one end of the first hollow conductive tube at a feed region of the sleeve dipole antenna, wherein the transmission feed line is operably configured as a ¾-wavelength transformer; and a single, coaxial shunt resonator coupled to the sleeve dipole antenna for impedance compensation, wherein the coaxial shunt resonator is formed from a length of coaxial cable, which extends along the longitudinal axis of the sleeve dipole antenna between opposite ends of the first hollow conductive tube.
