Abstract
The present invention discloses a millimeter-wave dual circularly polarized lens antenna and electronic equipment. The antenna includes a broadband circularly polarized planar feed source array and a dual circularly polarized planar lens. In the planar feed source array, a double-layer stacked patch is used at the same time to achieve broadband circular polarization, and a sequentially rotating feed structure is used to further expand the bandwidth. In the planar lens, a miniaturized stacked patch and a microstrip true-time-delayed phase-shifting structure are used to obtain the independent regulation and control of the left-handed and right-handed circularly polarized wave transmissive phases in a relatively wide frequency band. The lens antenna of the present invention achieves dual circularly polarized highly directional beam, and independently control the beam pointing of the left-handed circularly polarized wave and right-handed circularly polarized wave, and achieve the transmissive dual circularly polarized beam shaping.
