Abstract

The invention provides an antenna and communication equipment, and belongs to the technical field of antennas. The antenna comprises a horizontally-polarized antenna and a vertically-polarized antenna which are arranged in a stacked mode; the horizontally-polarized antenna comprises a metal sheet, and the metal sheet can be connected with a double-sided parallel strip line in the horizontally-polarized antenna and a first conductor of a coaxial cable. The diameter of the maximum inscribed circle of the metal sheet is larger than the line width of the double-sided parallel strip line, and the metal sheet and the coaxial cable are both positioned on the first side of a substrate, so that the metal sheet can effectively inhibit the induction current in the coaxial cable, the influence of the induction current on the vertically-polarized antenna can be reduced, and therefore, the isolation degree between the horizontally-polarized antenna and the vertically-polarized antenna can be effectively improved on the premise of avoiding increasing the overall height of the antenna.

Description

technical field [0001] The present application relates to the technical field of antennas, in particular to an antenna and a communication device. Background technique [0002] In a wireless local area network (wireless local area network, WLAN) service, in order to increase the signal bandwidth of an access point (AP), more antennas can be integrated in the AP to increase the number of signal streams, and the AP can use A combination of differently polarized antennas reduces channel correlation. For example, an AP may adopt horizontally polarized antennas and vertically polarized antennas that are superimposed. [0003] In order to reduce the height of the antenna and realize the low-profile design of the antenna, the distance between the horizontally polarized antenna and the vertically polarized antenna is generally relatively short. [0004] However, since the horizontally polarized antenna generally uses a coaxial cable for feeding, the coaxial cable will generate an ...
