Problems solved by technology
However, the total size of the device is still 12.5 × 8.9 square centimeters. The new topology only solves the problem of saving the area of one end of the transmission or reception, and the low-frequency energy transmission efficiency is not ideal, and the energy consumption is relatively large.

Embodiment Construction
[0014] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0015] This embodiment is carried out on the premise of the technical solution of the present invention, and the detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.
[0016] The signal source of the transmitting end is DC power supply. The DC power supply transmits the signal and converts the direct current into alternating current through the DC-AC converter. The alternating current passes through the circulator and transmits the signal through the No. 1 antenna of the transmitting end. The signal received by the No. 1 antenna is filtered by a low-frequency filter and then reaches the rectifier. The rectifier converts the signal from AC to DC and supplies power to the low-noise amplifier. After the receiving antenna at the receiving end receives ...

The invention provides an electric energy and electromagnetic signal short-range wireless transmission system of a shared channel, and relates to the field of wireless transmission. A transmitting end converts direct current into alternating current, and emits a signal after the alternating current passes through a circulator, the signal received by a receiving end arrives at a rectifier after being filtered by a low-frequency filter, the rectifier converts the signal from the alternating current into the direct current so as to supply power for a low noise amplifier, the receiving end amplifies a communication signal through the low noise amplifier, the amplified signal is emitted through the circulator of the receiving end, the receiving end filters the communication signal through a high frequency filter via the circulator, and the filter signal arrives at a receiver. According to the electric energy and electromagnetic signal short-range wireless transmission system, two transmission modes, that is, mutual inductance coupling transmission between coils and electric field coupling transmission between parallel board capacitors are combined, so that the double frequency transmission efficiency is greatly improved under the condition that the total volume of the device is unchanged.
Description
technical field [0001] The invention relates to the field of wireless transmission, in particular to a wireless transmission system of electric energy and electromagnetic signals. Background technique [0002] There are roughly three ways to realize wireless energy transmission, namely, wireless energy transmission technology based on electromagnetic induction, magnetic resonance coupling, and microwave or femtosecond laser. For short-distance energy transmission, electromagnetic induction or magnetic resonance coupling theory is often used to design transmitting and receiving antennas, but the near-field magnetic field coupling method uses a large coil size and low transmission efficiency, which is not suitable for vehicles. In multi-frequency wireless transmission, in order to achieve impedance matching at two frequencies at the same time, multiple coils are generally used to transmit signal energy of different frequencies respectively, and the parasitic coupling generated...
