Abstract
The present invention will yield enhanced gain over a conventional antenna system by taking advantage of combining directional antennae. In one embodiment, the invention utilizes four 10 dB dipole, vertically-polarized, omni-directional antennae having a reflector added to each one to limit the horizontal beamwidth to 90.degree. and increase the gain to 16 dB. The vertical beamwidth remains at 7.degree.. By utilizing four of these antennae and utilizing power combining hybrids to connect each of the two opposed antennae together, excess gain over a 10 dB omni-directional system will be obtained. The effective antenna gain is equal to the directional antenna gain minus the omni-directional antenna gain minus the hybrid loss. Thus, the vertical beamwidth and physical height of the antenna are preserved with the increase in gain at the cost of a little antenna complexity.
