This paper first introduced the concept of radio frequency identification technology, the rise and development. Radio frequency identification system with the basic structure and principles, described the antenna transceiver and the working principle of the process. Subsequent analysis of the transmitting power, receive power chip, chip power consumption and receiving antennas to receive the echo of the relationship between power and to examine in detail the chip to receive power and receiving antennas to receive the echo power as a range of changes, as well as the decision The size of these power factors, the actual design of radio frequency identification hardware to provide reference data.
