| Abstract: | An all-dielectric metalens antenna operating at the millimeter-wave is proposed based on phase compensation principle.A horn antenna is used as the source to feed the lens.To achieve large phase compensation,the height of the dielectric unit and the depth of the hole are changed.The lens is composed of 506 units with an aperture size of 44.6 mm × 46.6 mm.The focus-to-diameter ratio(F/D) of the lens is 1.Due to the all- dielectric structure,3D printing technology can be used to process the lens to reduce the processing cost.The simulation and measurement results show that the proposed antenna has a peak gain of 29.7 dBi at 82 GHz.In addition,the proposed design achieves a 1 dB gain bandwidth of 20.5% and a peak aperture efficiency of 52.55%(73.2~90 GHz). |
