Irregular antenna coil
The irregular wireless charging coil includes an RFID reader/writer, an irregular antenna body electrically connected to the RFID reader/writer, and when a device or product equipped with an RFID tag approaches the irregular antenna body, the RFID reader/writer reads the RFID tag information on the device or product and sends the information back to the system platform for verification.
Irregular antenna coils usually refer to wire windings in a circular shape, and the most common coil applications include motors, inductors, transformers, and circular antennas; The coil in a circuit refers to an inductor, with one or more guide wires wound in parallel, and the wires tightly and insulated from each other; However, in some special fields, there may be some irregular coils, such as wires that need to be wound around coil magnets with fan-shaped openings. Due to the special nature of coils, the current technology for wireless charging coils is to manually wind the coils. However, this method is not only due to uneven force of manual winding, resulting in different degrees of tightness of the wound coils, which may cause damage to the wires during subsequent use, but also due to low manual efficiency, resulting in increased costs.
