Abstract (en)

To address the issue of adding additional RF carriers to a transmitted signal in support of subscriber growth, an antenna configuration is utilized with orthogonally polarized transmission antenna pairs. The orthogonally polarized antennas are preferably arranged in substantially a +45 DEG /-45 DEG relationship and substantially maintain co-phase centers. By utilizing pairs of orthogonally polarized antenna components, the number of antennas necessary to transmit carrier signals can be halved. Further, undesirable size and space limitations can be avoided without a substantial loss in output carrier signals and without substantial signal interference.
