1. An antenna assembly comprising:

  • a right hand circularly polarized (RHCP) antenna;

    a left hand circularly polarized (LHCP) antenna;

    an RF nuller operably coupling the RHCP antenna and LHCP antenna to a balun circuit or balun component configured to operate as a difference element; and

    a digital nuller operably coupled to the balun circuit or balun component,wherein the RF nuller operates to perform coarse nulling before the balun circuit or balun component, and the digital nuller operates to perform fine nulling after the balun circuit or balun component to conduct null steering to steer a null in a direction of interference received at the antenna assembly.
