Broadband dual-polarized omnidirectional antennas

A broadband dual-circularly polarized (right-handed and left-handed) omnidirectional antenna and a broadband dual-linearly (horizontally and vertically) polarized omnidirectional antenna are presented. Both dual-polarized omnidirectional antennas have a bandwidth of about 30%. Good omnidirectional radiation patterns are obtained for both polarizations. An eight-element antenna array for each of the broadband dual-polarized omnidirectional antennas is developed.
