| Abstract: | The technology of radio frequency automatic object identification is discussed. It utilizes microwave andtransmitter/receiver antenna to realize automatic identification of far distance object. The technology includes multichannelhormodyne, reflection modulating without radio frequency source and beam powered by radio frequency energy.A system of radio frequency automatic object identiiieation is developed. The transmitter/receiver of the automaticobject identification system operates at the same frequency with the advantage of sparing frequency resource. Itoperates at 915 MHz with 1.5W output power. The RF card adopts the structure of planar dipole. The maximumidentification distance is up to 10 meters, the data rate reaches 10 kb/s. It can display automatically the data controlledby compater and print the report forms. |
