A Magneto-Electric Dipole Antenna with Switchable Circular Polar...

A polarization reconfigurable magneto-electric (ME) dipole antenna with broad bandwidth is.proposed and investigated. Two crossed dipoles through a 90◦ phase delay line, constituting a sequentially.rotated configuration, is used to feed the ME dipole. By manipulating the states of four p-i-n diodes which.are inserted in the crossed dipoles, the antenna is able to switch the polarization between two orthogonal.circularly polarized states. To verify the performance, the proposed antenna is designe
