The different sizes of circular tag antennas have been designed. The different sizes of circular tags will be fit to any circular object such as bottle caps of cosmetics. The outer radius from 8 mm to 40 mm of tags have been fabricated and tested. The 12 mm circular tag has about 1 m reading distance, and 35 mm tag has about 5 m. The relationship between… CONTINUE READING
