Abstract
Radio Frequency Identification technology is a kind of wireless information
communication method developed in recent years . It's a non-contact method to
achieve the exchange of information between the host and the information carrier.
Compared with traditional information transmission methods, radio frequency
identification technology has the advantages of removable, multi-target recognition,
operating simply and effectively. After several years development , radio frequency
identification technology has been widely used in shopping malls and retail, transport
and smart access control, identification, and other fields. Its advantages and prospects
are obviously, so the exploration and research of radio frequency identification
technology are extremely important and significance
This paper firstly introduces the history and development of radio frequency
identification technology, and discuss the bottlenecks in the development of radio
frequency identification technology. Secondly the basic principles of radio frequency
identification and constitute are discussed, the paper pointed to the design methods and
key points of identification antenna. Finally, we designed two kinds of the radio
