description | An antenna structure suitable for 5G use in controlling direction of radio beams and in increasing antenna gain includes a substrate, an array of antennas, a main body, a lens array, a grounding plate, and a high-impedance surface (HIS) layer embedded into the substrate. The array of antenna units is positioned on the substrate surface under the protection of the main body. The lens array includes a lens units for each antenna unit, the lens units concentrate the beams generated by the antenna units. The grounding plate is underneath and grounds the antenna units. The HIS layer suppresses surface waves generated by the lens arrays and the substrate and increases a gain of the antenna structure in certain directions. |
