Design Of RFID Series Antennas Based On Internet Of Things

At present, the development of domestic Internet of things quickly;foreign to the IOT applications mainly concentrated in a few countries, Europe, Japan, Korea etc;With the development of RFID, sensor technology, short-range communication and computing technology, Its research and development is the main direction of bar code, RFID technology in the application of commercial retail, logistics field;In recent years, the research and development, application of began to expand to environmental monitoring, biological and medical treatment, intelligent infrastructure。At the same time, our country also vigorously develop the Internet of things, In the most recent NPC and CPPCC government work report also pointed out that, In2010to develop strategic emerging industries, accelerate the development of the applications of the Internet of things。Radio frequency identification (RFID) technology is one of the core technologies of the Internet of things, The most attention of the market at present, the concept of things related to the application of the highest degree or RFID. China’s RFID industry compared to Europe, the United States, Japan and other countries, a late start, But along with the national policy support, RFID industry has made considerable progress, Especially in the sensor chiphas reached the international advanced level.But in the reader and reader antenna, there is still a gap。The Internet of things is in fast development, the antenna play a decisive role in the Internet of things,The development of the antenna is directly related to the development of the Internet of things, According to the Internet for information exchange and communication needs, In this paper, the technology innovation, the specific work is as follows.1. using microstrip dipole antenna technology for the7dBi c-polar directional antennas and handset antenna;2. patch technology developed5dBi thin c-polar antenna,3. using near field theory developed near field scanning antenna, Application of the above technique can greatly reduce the volume of the antenna and improved the performance of the antenna, Can be applied to RFID dynamic traceability, warehouse management, logistics management, access control management, and many other fields of intelligent medical etc.The applications of the Internet of things will be everywhere, RFID is one of the main part of th is, Market demand is visible; And RFID, will use RFID reader antenna; In view of the current market demand for RFID system volume grow with each passing day; Will bring considerable economic benefit; On the RFID development trend, this research and development is very promising.
