Multi-Polarized High-Gain Omni Directional Arrays

In recent years, the need for high gain omnidirectional antennas increased considerably. The antennas are used in a variety of bands anywhere from VHF to millimeter waves bands, in different configurations which mainly differ in gain. The omnidirectionality is mostly obtained using back-to-back elements or simply using dipoles in different collinear-array configurations. The antenna proposed in this paper is an array of cylindrical patches which generates an omnidirectional pattern in the azimuthal plane. The polarization can be either linear or circular.
