摘要：
A radio frequency (RF) identification tag including a substrate, a planar antenna, an RF chip, a plurality of signal conductors and a plurality of ground conductors is provided. The RF chip receives an RF signal from the planar antenna to generate an identification code. The signal conductors are coupled to the planar antenna. The ground conductors, interlaced on two opposite sides of the signal conductors, and the signal conductors are adjacent to each other and disposed on the substrate to form a coplanar waveguide structure which includes an impedance match portion and a transmission portion. The impedance match portion has an input end coupled to the signal conductors and a ground plane coupled to the ground conductors. The RF chip is disposed between the input end and the ground plane. The transmission portion is connected between the impedance match portion and the planar antenna.
