Abstract

A quadrifilar helical antenna with polarization and pattern reconfigurabilities is proposed. The proposed antenna consists of a reconfigurable radiator and a switchable feeding network. The radiator combines two individual QHAs which can be alternatively activated. The feeding network provides switchable quadrature excitations to the radiator. By controlling the PIN diodes, the antenna can provide RHCP/LHCP waves with broadside/backfire radiation patterns. Simulated results show that the proposed antenna obtained wide impedance and axial-ratio bandwidths (18.6% and 44.2%, respectively) with a compact size (0.26 λ0×0.26 λ0×0.23 λ0).
