ABSTRACT:
An omnidirectional dual band antenna system includes a radome and an antenna in the radome. The antenna has a linear array of lower frequency band driven elements, a linear array of higher frequency band driven elements and a linear array of parasitic elements, spaced in parallel planes with the array of higher frequency band driven elements in the middle. The parasitic elements couple to the higher frequency band driven elements and reshape the radiation pattern of the higher frequency band driven elements to correct for distortion caused by the lower frequency band driven elements.
