摘要： An antenna array and a communications device are provided. The antenna array includes a feeding waveguide and a waveguide cover. A waveguide port is disposed on the feeding waveguide, and an array of radiation slots are arranged along the length of the waveguide cover. The slots are configured to transmit signals fed from the waveguide port, and are classified into a first subarray and a second subarray. At a center frequency of the antenna array, the difference between a beam angle of the first subarray and a required beam angle, and a difference between a beam angle of the second subarray and the required beam angle, is each less than a specified threshold. With a frequency change of the antenna array, the beam angle of the first subarray and the beam angle of the second subarray change in opposing directions. Therefore, when the first and second subarray beams are combined, the combined beam angle has reduced frequency dependence.

摘要： An antenna having high isolation and a low cross-polarization level, a base station, and a terminal are provided. The antenna includes a radiation layer, a feed layer, and an aperture coupling layer disposed between the radiation layer and the feed layer. The aperture coupling layer includes a metal sheet. A first feeding slot, a second feeding slot, and a middle slot are configured in the metal sheet. The middle slot is located between the first feeding slot and the second feeding slot, and is located in a weak electric field region of the metal sheet. The middle slot is configured between the first feeding slot and the second feeding slot of the metal sheet.
