A SLENDER-DIRECTIONAL, BROAD-BAND, HIGH-EFFICIENCY, DUAL-POLARIZED SLOT/DIPOLE ANTENNA ELEMENT

摘要

The present invention is directed toward a dual linear or circular polarized antenna comprised of two orthogonally linearly polarized radiative elements. More specifically, the present invention is for a slender slot-dipole antenna, where the slot and the dipole are located in the same physical structure. Feed line interference to the antenna can be eliminated by including a centrally located shaft. The antenna of the present invention can be used as either a receive antenna or a transmitting antenna and could be used to form an array. In one embodiment, the antenna is comprised of two substantially cylindrical members, wherein the slot is located on the outer surface of the antenna and the cylindrical members function as dipoles. Other embodiments are directed toward multiple slots and polygonal-shaped antennas.
