The invention discloses a transmitting antenna for improving the degree of freedom and distance in magnetic resonance wireless power transmission. The transmitting antenna comprises an exciting coil and a transmitting resonance coil, the exciting coil is a planar multi-turn coil; the transmitting resonance coil is formed by connecting two planar multi-turn coils in series; and the exciting coil is used for feeding in electromagnetic energy and coupling the electromagnetic energy to the transmitting resonance coil, and the transmitting resonance coil couples the electromagnetic energy to the receiving coil through magnetic resonance. The transmission efficiency of the transmitting antenna is kept stable at different charging distances and high-distance inclination angles; and the transmitting antenna is of a broadband matching structure, when receiving is carried out at different positions in a transmitting antenna field, the input impedance change of the transmitting antenna is very small, and matching between the output impedance of the power amplifier and the input impedance of the transmitting antenna is ensured.
Description
technical field [0001] The invention belongs to the technical field of wireless power transmission, and in particular relates to a transmitting antenna for improving the degree of freedom and distance of magnetic resonance wireless power transmission. Background technique [0002] With the continuous development of electronic information technology and automation control technology, various home appliances, consumer electronics, mobile communication equipment, etc. have been widely popularized. However, traditional household appliances rely Electronic devices with built-in batteries also need a wired connection between the charging cable and the power outlet for charging, so we can see wires that provide power supply for these electronic devices everywhere. These wires not only occupy our activity space, limit the convenience of equipment use, but also create hidden dangers for safe use of electricity. Therefore, with the growing demand for portable devices and green energy...
