Radio frequency antenna with longdistance identifying function

Abstract

This invention relates to a RF antenna with far distance identifying function including at least a transmission conductor electrically connected with an earth conductor and an identification chip to make said RF antenna to transmit RF communication signals and RF identification signals, said identifying chip can link up with external fetch devices by said RF antenna and said RF identification signal to increase the RF identification link-up ability of the external fetch device with the identification chip.

Description

technical field [0001] The present invention relates to a radio frequency antenna, in particular to a radio frequency antenna with long-distance identification function and can be used in wireless communication equipment, which can not only improve the radio frequency identification communication ability between an external reading device and an identification chip, but also simplify the identification chip The antenna design and the effect of reducing the installation cost. Background technique [0002] With the frequent international trade and the increasingly refined division of labor, the flow of goods between countries is huge, so the control of goods has become very important and complicated. Traditionally, the number of stripes permutated and combined to identify barcodes is used to represent the data of goods. The identification and reading method can no longer meet the needs of the current product number, so a radio frequency identification label that can be fixed o...

Problems solved by technology

[0004] However, in this wireless communication device 155, it still includes an external antenna 155 that can carry out radio frequency communication signals 197. The existing structure cannot integrate the external antenna 155 and the chip antenna 113, so it will cause a waste of resources.

[0005] Therefore, the radio frequency identification tag 11 needs to be pasted or fixed on the outer surface of the goods 15 to facilitate the reading of data by the external reading device 19, but it will also affect the overall appearance of the goods 15.

[0006] Moreover, the radio frequency identification label 11 is directly fixed on the outer surface of the goods 15, which is easy to be damaged by foreign objects during the transportation of the goods 15, or is removed and stolen by interested people in the store, resulting in many disadvantages

[0007] In addition, the general radio frequency identification tag 11 needs to provide the operation and use of the identification chip 111 according to the induction energy of the radio frequency identification signal 195 of the external reading device 19, and this will also limit the function and working efficiency of the radio frequency identification tag 11

Even if another semi-active or active radio frequency identification tag 11 can use an additional battery to provide a working power for the radio frequency identification tag 11 to improve its function and work efficiency, but when the battery power is exhausted , will cause the radio frequency identification tag 11 to lose the ability to sense the surrounding environment of the goods 15 or actively provide the goods data 115 to the external device 19, which will cause blind spots in the management of the goods 15, thereby affecting the management and operation of the goods 15

[0008] Due to manufacturing cost considerations, the general RFID tag 11 only uses a simple loop antenna 113 as its chip antenna, so when the goods 15 are stacked or blocked by electromagnetic barriers, the transmission of the RFID signal 195 will be poor. Relatively, it will cause the external reading device 19 to fail to obtain the product data 115 smoothly, causing loopholes in the logistics management, thereby delaying the entire circulation process of the product 15
