1. An antenna system for a wireless communication system, comprising:

  • an antenna configured to receive and transmit circular polarized transmissions in a spread spectrum system;

    a drive system operable to produce at least two outputs having generally the same amplitude and a phase difference relative to one another, each output being coupled to a different portion of the antenna; and

    a controller operable to dynamically switch the outputs between clockwise and counterclockwise transmissions to define two subsystems configured for simultaneous operation.
