Abstract
An antenna array is described in which a feed line that is formed by metal atterns on opposite sides of a circuit board has a plurality of pairs of adjoining quarter wave resonant sections formed by different widths of the patterns and dipoles respectively coupled to the junctions of the pairs of quarter wave sections. The proximity between dipole elements and the feed line is sufficiently close to enable a nearly symmetric azimuthal antenna beam pattern. Each dipole further uses capacitive compensation at its center to balance the capacitive loading with the closely spaced feed line.
