ABSTRACT:
A cylindrical, omnidirectional antenna array includes a plurality of vertically spaced circular rows and a plurality of angularly spaced vertical columns, with an antenna element located at each row-column intersection. The antenna elements included in one 180.degree. sector of the cylindrical array are vertically polarized, while the antenna elements included in the other, diametrically opposed 180.degree. sector are horizontally polarized to provide polarization diversity. Optionally, the antenna may be adapted as a sector antenna array by reducing the number of columns and the angles of the diametrically opposed sectors to less than 180.degree..
