1. A radio frequency system for use in a cellular network, the radio frequency system comprising:

  • an antenna array including a plurality of antenna elements configured to generate a plurality of receive signals in response to a radio wave, each of the plurality of antenna elements configured to generate a corresponding one of the plurality of receive signals;

    a plurality of signal conditioning circuits each thereof operatively associated with a corresponding one of the plurality of antenna elements, the plurality of signal conditioning circuits configured to process the plurality of receive signals to thereby form a receive beam; and

    a beam control circuit configured to control the plurality of signal conditioning circuits to provide beam steering of the receive beam based on a direction of one or more harmonic lobes of the receive beam.
