发明名称 RADIO FREQUENCY IDENTIFICATION TAG ANTENNA USING PROXIMITY COUPLING FOR ATTACHING TO METAL
摘要 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.
