Electrically Controllable Ferroelectric Lens for Beamforming in the Millimeter-Wave Band

The design of the electrically controlled beamforming lens for millimeter wave range is considered and analyzed. The lens is based on a periodic structure consisted of ferroelectric and linear dielectric layers. The functional purpose of the developed lens is the formation of a narrow beam pattern. The full-wave simulation was performed to demonstrate the beamforming lens functionality. The results show a significant increase of feed antenna directivity value from 7 to 12 dBi by the use of the proposed lens.
