Abstract

In this letter, we show that the inclusion of a pin diode suitably positioned in a circular wire-loop antenna mounted over a ground plane can be used to electronically control the polarization radiation properties of the antenna. Specifically, we use a gapped circular wire loop of circumference 1.13λ_o at 1 GHz positioned 0.3λ_o above a 33 cm × 33 cm ground plane. Inclusion of a pin diode into a 2.7-mm gap, suitably positioned with respect to the generator, allows the antenna current distribution to be electronically controlled such that the loop produces linearly polarized radiation VSWR of 1.8 or circularly polarized radiation VSWR of 2.5, boresight axial ratio less than 2.5 dB.
