Abstract
An improved magnetically coupling near-field RFID antenna is embodied as a magnetic H-field coupler, and the near-field RFID antenna is embodied as a looped and/or frame-shaped antenna. The looped and/or frame-shaped antenna comprises a looped or frame-shaped strip conductor. The strip conductor is arranged set apart from a ground surface parallel thereto. A dielectric is interposed. The start and the end of the strip conductor end close to each other forms a gap or spacing. The start of the strip conductor is fed to ground. The end of the strip conductor is terminated by a terminating resistor. The terminating resistor is connected between the end of the strip conductor and a ground surface.
