摘要: We explore structures of planar tag antennas that permit high efficiency, a low profile, and reliable performance on variety dielectric materials. For the basic structure antenna, we used inductively coupled feed concept to efficiently reduce size antenna. examined two different types windings for antenna body achieve better with given RFID chip. To find detailed design parameters attain multiple goals, employ Pareto genetic algorithm an IE3D Zealand EM simulator. The finalized designs were built 5 mil thick Duroid substrate Alien optimal was reduced kr=0.2, readable range 40 cm-280 cm.
