The invention discloses an antenna with grounded U-shaped high-impedance surface
metal strips and a
wireless communication device with the antenna. The antenna is arranged in a housing, and comprises an
antenna radiation unit and a grounding plate thereof. A plurality of high-impedance surface units are arranged at intervals on the grounding plate, and each high-impedance surface unit consists ofthree sections of high-impedance surface
metal strips which are connected to form a U shape. High-impedance surface through holes are formed on the bottom edges of the U shapes, and are used for connecting the high-impedance surface
metal strips among the high-impedance surface units. Due to the adoption of the plurality of U-shaped high-impedance surface units, the antenna and the
wireless communication device suppress or prevent surface
waves from being propagated along the surface of the antenna on one hand, and perform same-phase reflection on plane
waves incident vertically to the surface of the antenna on the other hand; the antenna and the
wireless communication device reduce
radiation on a head, reduce
radiation energy absorbed by the head and reduce a
specific absorption rate by utilizing the
surface wave suppression characteristics of the high-impedance surface units arranged around the antenna; and simultaneously, the
radiation performance of the antenna may not be reduced,the
communication quality may not be influenced, and the antenna and the wireless communication device have universality and universal applicability.
