Abstract

The invention provides a multiprotocol UHF reder which adopts a label with a frequency band of 860 to 960MHz and supporting various protocols. The reder consists of a digital control module, a RF transmitting module, a local oscillator signal module, a RF receiving module, a receiving and transmitting isolation module, a RF switch set and an antenna group. The reder integrates a plurality of international standards of UHF like EPC Class 1, EPC Class 1 Gen 2 and ISO18000-6PART B. The reder adopts a modularization design; the circuits are simple and the cost is low. The reder can be applied to a plurality of different occasions like logistics and electronic toll collection.

Description

technical field [0001] This patent relates to a multi-protocol ultra-high frequency reader, specifically related to radio frequency microwave technology, testing technology, electromagnetic theory and other fields, especially in the field of radio frequency identification technology. Background technique [0002] Radio frequency identification RFID is a non-contact automatic identification technology, which uses radio frequency signals and space coupling to realize automatic identification of objects. Compared with barcodes, RFID technology has the advantages of waterproof, antimagnetic, long service life, long reading distance, data encryption on labels, large storage data capacity, and convenient change of stored information. RFID has brought profound changes to human life. RFID technology is applied in different occasions, such as logistics, non-stop toll collection, etc. According to different industries and application occasions, there are different requirements for RF...
