Abstract

Self-phasing can be achieved in a quadrifilar helix antenna (QHA) by displacing one of the bifilars along the axis of the helix, yielding a circularly polarized cardioid shaped pattern. Impedance bandwidth of 10% (2105-2345 MHz) has been achieved with Front to back ratio greater than 10 dB
