NEAR-FIELD RFID READER ANTENNA

摘要

PURPOSE: A near-field RFID reader antenna is provided not to recognize long distance tags by uniformly generating an electric field or a magnetic field in various directions in a neighboring range. CONSTITUTION: At least one signal wires(120) are formed on the top surface of a dielectric layer(110). A ground plane(160) is formed in the lower part of the dielectric layer. At least one grounding conductors(140) are electrically connected to the ground plane. The grounding conductor is parallel with the signal wire. At least one signal stubs(130) are electrically connected to the signal wire. At least one grounding stubs(150) are electrically connected to the grounding conductor.
