Abstract :
A switchable linear/circular polarised ferrite resonator antenna is investigated. It is shown that the polarisation can be switched from linear to circular by applying a static magnetic bias to the ferrite resonator antenna. The return loss and radiation patterns for the two polarisations are presented
