Description

technical field [0001] The invention relates to the technical field of communication, in particular to a high-isolation dual-polarization cavity radiation unit. Background technique [0002] The antenna is a key device for transmitting and receiving electromagnetic waves in a wireless communication system. Anything that uses electromagnetic waves to transmit information depends on the antenna for work. With the rapid development of modern wireless communication technology, on the one hand, the communication system is required to be miniaturized, and on the other hand, the communication capacity of the system must be further improved. In order to meet the growing communication needs and diverse application scenarios, antenna technology is also developing towards the direction of broadband, multi-polarization and high gain. In multi-antenna practical applications, including for diversity realization and multiple-input multiple-output (MIMO) system applications, it is common t...
