Abstract
An antenna element includes a first impedance structure, a second impedance structure, and a polarization rotating element. The first impedance structure includes a first dielectric slab and a first conducting pattern layer mounted on the first dielectric slab. The second impedance structure includes a second dielectric slab and a second conducting pattern layer mounted on the second dielectric slab. The polarization rotating element includes a third dielectric slab, a third conducting pattern layer, a first switch, a fourth conducting pattern layer, and a second switch. The third conducting pattern layer is mounted between the third dielectric slab and the first dielectric slab and forms a first dipole dependent on a position of the first switch. The fourth conducting pattern layer is mounted between the third dielectric slab and the second dielectric slab and forms a second dipole dependent on a position of the second switch.
