The invention discloses a device and method for forming a controllable broadband magnetic wave beam based on a double helical coil unit sheet. The device is formed by stacking several double helical coil unit sheets. The double-helical coil unit sheet is a double-layer circuit board with helical coils arranged on the front and back sides, and an inner hole is arranged in the center of the board surface, and the helical wires on the two surfaces are connected at the inner end, and the circulation direction is consistent. Parameters such as the coil shape, the number of turns, the pitch of turns and the line width of the double helical coil unit piece can be precisely adjusted, the manufacturing process is consistent, and it is easy to miniaturize and integrate. The controllable magnetic wave beam forming device is composed of several helical coil units of different sizes, and the serial and parallel connection mode between the units can be set through the numerical control circuit to adjust the electrical parameters such as the resistance and inductance of the device, and then adjust the resonant frequency and bandwidth of the system ;The main lobe of the magnetic wave can be adjusted by setting the inner hole of each helical coil unit in the combination; the magnetic wave side lobe can be adjusted by setting the overall envelope shape of the unit combination; the power of the device can be adjusted by setting the number and size of the overall unit pieces of the combination device , The adjustment of the magnetic wave emission distance.
Description
technical field [0001] The invention belongs to the technical field of wireless detection and wireless energy transmission, in particular to a controllable broadband magnetic wave beam forming device and method. Background technique [0002] In the field of magnetic-based wireless detection or wireless energy technology, the conversion of electrical signals and magnetic signals, or electrical energy and magnetic energy is an important link. The electromagnetic induction coil is the main device to complete this part of the function. Most of the traditional induction coils are wires wound manually or mechanically to form a planar helical coil or a three-dimensional helical tube. The consistency and controllability of the manufacturing process of this kind of wound coil is not high, and the precise control of the number of turns, turn pitch, and line width of the coil is difficult to achieve. Moreover, the wound coil sometimes has stress rebound, resulting in a deviation betw...
