摘要：
An RF tag to accompany a conductive object is disclosed that includes an antenna and an integrated circuit connected to the antenna. The antenna includes a first radiating element, a second radiating element, a feeding part connected in series between the first and second radiating elements, and an impedance control part connected parallel to the feeding part. The antenna has an effective length shorter than half of a wavelength used in communication.
