Radio frequency identification tag antenna using proximity coupling for attaching to metal

Image Number 3 for United States Patent #7876269.

An antenna attached to an object and transmitting electromagnetic waves that are modulated by an RFID tag chip includes a polygonal dielectric material layer that is adjacent to the object, a microstrip patch that determines a resonance frequency of the antenna, a microstrip line that is electromagnetically coupled with the microstrip match, and a shorting pin that disconnects the object and the microstrip line. Accordingly, a small-sized antenna that can be attached to metal can be realized.
