[0002] Traditional conductive slip rings realize signal and power transmission through sliding contact. The bandwidth of data transmission is low. The weak current signal transmission part is easily interfered by the strong electric power transmission part. During the sliding contact process, it is easy to generate sparks, poor contact and other problems. For this reason, Chinese patent number: 201110247827.9, invention patent name: "wireless power supply and signal transmitter", this invention discloses a wireless conductive ring technology for high-speed data and power transmission, the signal is transmitted by coupling the upper and lower parts, but It is only suitable for satellite signal reception in the tuner, and cannot be used in turntable equipment that needs to send and receive high-speed digital signals. Chinese patent number: 201320482293.2, utility model name: wireless conductive ring, the wireless conductive ring technology disclosed in this utility model is also Satellite radio transmission is realized by coupling, which does not involve high-speed data transmission, and cannot be applied to applications such as high-speed video signals. The above-mentioned wireless conductive ring can only transmit radio analog signals, and does not involve signal modulation and demodulation technology, so it cannot be applied to high-speed applications. In digital signal transmission equipment, in some monitoring and optical application fields, the conductive ring is required to be a hollow conductive ring, so it is impossible to use optical fiber communication to increase the communication rate. The data transmission bandwidth of the existing contact conductive ring is generally at the level of 100 megabytes. However, conductive rings used in some fields such as video surveillance target tracking require data transmission bandwidths of several Gbps or even tens of Gbps. Based on the high-frequency characteristics of millimeter waves, wireless data transceiver modules based on millimeter waves are used to achieve non-contact high-speed data transmission. transmission
