Description

technical field [0001] The invention relates to the field of communication, in particular to a dual-polarized high-isolation antenna array and communication equipment. Background technique [0002] In recent years, with the rapid development of modern wireless communication technology, the fifth-generation mobile communication has become the focus of the current mobile communication industry, and the research and development of 5G systems for the 2020s is in full swing worldwide. Antenna is an important part of wireless communication system, and its research and design play a vital role in mobile communication. The future 5G system will focus on higher data transmission rate, larger channel capacity and higher performance requirements, which can no longer be met by a single antenna. Larger and larger antenna arrays will become the key to increase gain and obtain more channels and information. The inevitable choice of capacity. In order to improve communication transmission...
