A method for manufacturing an RFID radio frequency antenna by punching an aluminum foil. A complex RFID radio frequency antenna pattern is decomposed into two or three groups of simple segment patterns, then two or three groups of punching dies are manufactured according to the two or three groups of segment patterns, aluminum foil segments punched respectively are connected to one another in a lapped mode, the lap joint parts of the aluminum foil segments are welded using ultrasonic waves or treated using an acupuncture process, and the two or three groups of punched aluminum foil segments are combined to form a complete radio frequency antenna. According to the method, an aluminum foil radio frequency antenna can be manufactured by punching on paper, films and rubber having different thicknesses, radio frequency products of different materials can be manufactured conveniently, the production process is simple, generation of waste water is avoided, and pollution to the environment is avoided; moreover, aluminum foil waste is easy to recover, efficiency is high, the manufacturing cost is low, and the aluminum foil radio frequency antenna is suitable for large-scale production. |
