Abstract
A switchable polarization operation of an annular ring monopole antenna realized with a PIN diode load is presented. It is shown that the antenna polarization is switched from circular polarization (CP) to linear polarization (LP) with a change of the PIN diode state from off to on. Technically, with the state change, the current distribution on the ring is altered between that of asymmetric (for CP) and symmetric (for LP). Also, an inverted sleeve is included for an improvement on the axial ratio for the CP operation.
