Embodiment Construction

[0033] Please refer to figure 1 , Is a schematic diagram of the module of the dual radio frequency reader based on the radio frequency identification technology and IC card technology of the present invention. The dual radio frequency reader 2 generates read and write control commands under the control of the computer system 1, and the dual radio frequency reader 2 The read and write control commands are radiated outward in the form of electromagnetic waves through the electromagnetic composite material antenna 3. The electronic tag 4 or IC card 5 responds to the read control command and transmits data information back to the dual radio frequency card reader 2.

[0034] The dual radio frequency card reader 2 includes an electromagnetic composite material antenna 3, an RFID reading and writing module 22 and an IC card reading and writing module 23. The electromagnetic composite material antenna 3 radiates or receives electromagnetic wave signals in the first frequency band based o...

Abstract

A dual-radio-frequency card reader comprises an RFID (radio frequency identification device) read-write module, an IC (integrated circuit) card read-write module and an electromagnetic composite antenna. The electromagnetic composite antenna radiates or receives an electromagnetic wave signal in a first frequency range based on a read-write control instruction of the RFID read-write module, and further radiates or receives the electromagnetic wave signal in a second frequency range based a read-write control instruction of the IC card read-write module. With the adoption of the design of the electromagnetic composite mode, the physical length of the antenna is increased equivalently (while the practical length and the dimension are not increased), and the width of the frequency range and the amount of resonance frequency points covered by the antenna are all increased due to the design; therefore, multiple antennas can be replaced by one electromagnetic composite antenna; the dual-radio-frequency card reader can realize multi-frequency-range communication by using one antenna; the size of the existing dual-radio-frequency card reader is reduced; and the design cost is lowered. The invention also provides a wireless communication system comprising the dual-radio-frequency card reader.

Description

Technical field [0001] The present invention relates to the technical field of radio frequency identification, in particular to a dual radio frequency card reader based on radio frequency identification (Radio Frequency Identification) technology and IC card technology. Background technique [0002] The dual radio frequency card reader performs wireless communication with nearby electronic tags under the control of the computer. Because the dual radio frequency reader is based on radio frequency identification (Radio Frequency Identification) technology, the communication frequency band is 433MHZ or 900MHZ (optional). This frequency band is a public frequency band, which is convenient for application without application and charges; and the working frequency band for communication with IC cards It is 13.56MHZ. In order to meet the requirements of dual radio frequency card readers to achieve the above-mentioned dual-band communication, the dual radio frequency card reader is equi...
