Description

technical field [0001] The present invention relates to wireless communication technology, in particular to an antenna control circuit and method. Background technique [0002] As an important part of the wireless communication channel, the radio frequency antenna is the basic structure to realize wireless communication. With the development of communication technology, the data throughput requirements of users for wireless communication are increasing day by day, and the radio frequency antenna has also developed from the original single-antenna system to a complex MIMO (Multiple-Input Multiple-Output) antenna system. In order to ensure good communication quality, for complex antenna systems, each antenna must have good radiation characteristics. Any damage or abnormal connection of any antenna will affect the normal operation of the entire communication system, and may even cause damage to the front-end radio frequency. Damage to the link. [0003] At present, in order t...
