摘要: An antenna array is provided by stacking two PC boards in a superimposed relationship above housing acting as ground plane. Each of these contain thereon symmetrical arrangement photo etched or printed mat-strip power division networks and dipole elements providing linear polarization, the on one board being oriented with other to provide orthogonal polarizations. A plane for upper parallel, spaced conductive members superimposed, parallel board. In embodiment, are strips third disposed between first boards. another same lower therefore. formed ridges The so that they mutually transparent radiation from each fed balanced, symmetrically branched network carried associated combined balun divider coupling an input waveguide balanced line network. includes coaxial transmission having its center conductor connected directly extending radially directions network, this latter width conductors outer greater than tne at branching locations reflectionless impedance transformers predetermined length different given width.
