    摘要: An all-metal dual-polarized feeding element and an all-metal dual-polarized panel antenna are provided. According to the present disclosure, a first metal plate and M*N same waveguide radiating ports on the first metal plate form a radiating network. A second metal plate, a third metal plate, a fourth metal plate, a quadruple-ridged waveguide array, a first polarization feeding network, a second polarization feeding network, a coaxial to double-ridged waveguide array, and a double-ridged waveguide to quadruple-ridged waveguide array form a feeding network. Therefore, the dual-polarized feeding element and the dual-polarized panel antenna realize a wide bandwidth, a high efficiency and a low profile. The present disclosure solves problems of poor performance and hard realization of existing dual-polarized antennas in wide bandwidth, high efficiency and low profile.

    摘要: The present application discloses a coaxial dual-band antenna, including a waveguide tube, a ring groove, a high frequency feed, and a dielectric ring. The high frequency feed and the dielectric ring have a same axis with the waveguide tube. The waveguide tube has a tubular structure, and is configured to transmit a first electromagnetic wave, the ring groove whose opening direction is the same as an output direction of the first electromagnetic wave is on a wall of the waveguide tube. The high frequency feed is located in the waveguide tube. The dielectric ring is filled between the waveguide tube and the high frequency feed, and has a multi-layer structure. The area sizes of planes that are at layers of the dielectric ring and that are perpendicular to the axis alternately change, and a height of the dielectric ring is less than a height of the waveguide tube.

    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.
