VOLUME-LOADED SHORT DIPOLE ANTENNA

摘要

An electric dipole antenna (102) includes a first (108) and a second (110) arm extending along a dipole axis (106) away from a feed gap (126) in substantially opposite directions. A first (120) and a second (122) end body are operatively coupled to opposite ends of the first and the second arms. Each end body has a width deimension which extends perpendicular to the dipole axis. A dipole length dimension extends along the dipole axis through the first and the second arms and the first and second end bodies. A current conduction circuit provides a radiation field for the electric dipole antenna. The circuit passes along the first and the second arms and around a closed perimeter of the first and the second end bodies. The dipole exhibits a series resonant frequency at a wavelength which is at least eight times the dipole length dimension.
