Title The design of RFID reader

Abstract The technology of the Internet of things has already been widely used in many areas such as production management, intelligent transportation, smart power grid，warehousing and logistics。 In recent years, the business value of Radio frequency identification technology is being explored, and its huge development potential is getting more and more attention。 At present, those imported IC, used in UHF RFID products of our country，is much more expensive, which gives rise to the high price of the readers。

UHF RFID desktop reader and U-disk reader designed in this paper, can identify tags comply with ISO 18000-6 B/C。 In the hardware circuit architecture, OOK modulation is realized by switching power amplifier in transmitting chain, which is easy to implement。At first, this paper introduces the concept and development situation of Internet of things and RFID at home and abroad, makes a simple introduction of the existing technical difficulties and leads to the topic background and thesis structure。 Secondly, the paper gives the structure of UHF RFID system, design process of the research, principle structure of the design, key technology and chips selection。 Besides, this article respectively analyzes the hardware circuit design of the reader 。
