New description: • [New technical field] This creation involves a wireless sensing technology, especially an RFID query. * [Prior Art], ie ID (Radio Frequency Identification System) is the use of n buyer (Reader) to send radio waves to the responder (TranSp〇ncjer) for data identification, reading and management. Its working principle is to use the resonant circuit formed by the antenna to transmit/receive the wireless signal containing the chip identification code (ID c〇de) for data identification and transmission. Therefore, the inquiry H can be widely used in logistics management and production line automation. , warehousing management, access control, airport baggage management, smart labels and various value-added ticket cards and other applications. As shown in the first figure, the antenna 中 in the interrogator is made of a conductive material, and a zigzag-like coupling portion 2 and a silicon wafer 3 (RFIC) are disposed at appropriate positions of the electrical material. The wireless signal (vibration signal) including the ID code is generated by the cell D wafer 3, and the antenna 1 formed of a conductive material is returned to the reader. The RFID chip 3 described above is electrically connected to the open position of the meandering coupling portion 2 to form a circuit to conduct 'the control signal of the RFID chip 3 can be conducted on the joint portion 2, but since the coupling portion 2 is meandered, it is broken. The position forming-gap 4 causes the antenna 1 to have a strong directivity toward the coupling portion 2_gap 4 when transmitting the secret. Therefore, in terms of the overall signal coverage, the directivity of the recording is reversed. The range that can be sensed will be smaller.

Such an antenna design utilizing oxygen valley coupling, such as U.S. Patent No. 7,158, No. 33 B2 'at the time of manufacture' requires additional magnetic field coupling element 5 disposed on antenna 1 for use with its capacitive coupling element 6, and its capacitive coupling The element 6 and the magnetic field coupling element 5 are vertically overlapped, and the structure is highly demanded, and if no conductive block or other corresponding method is provided, the problem of directivity and signal coverage of the antenna is not solved. [New content] The purpose of this creation is to provide an antenna structure of RFID (Radi〇FreqUency Identiflcati〇n) interrogator, which can reduce the problem of wireless signal directivity of the responder and increase the effective sensing distance of the antenna (ReadRange ), and at the same time has the function of near field and far field sensing (transmitting/receiving).
