Background

With the progress of radio technology and the development of economic society, a great number of radio devices with various purposes and various industries have more and more radio frequency requirements, and once a certain service is defined by a radio spectrum of a frequency band, other services and even devices cannot utilize the frequency band, so that frequency resources increasingly become scarce resources. MIMO is a key technology adopted by a new generation of communication system, and increases the capacity of a communication channel by increasing the number of antennas, and the frequency spectrum utilization rate can be improved exponentially without increasing the bandwidth of an occupied frequency band and the transmission power of equipment, thereby more satisfying the rigid demand of communication services. On the basis of the MIMO technology, the 2.4G-5.8G dual-band electromagnetic signals input from the connector are effectively resonated and radiated to the outside through the combination of the reflecting plate and the radiating unit.
