Abstract

The disclosure concerns a signal aggregator component designed to couple with an antenna element to form an antenna system, wherein the resulting antenna system can achieve one-hundred percent or greater efficiency in receiving mode. In addition, the antenna system can achieve specific polarization and gain in different sectors of the antenna radiation pattern. The signal aggregator functions to dynamically enable or disable any number of its RF ports to select the RF input signal to aggregate.
