PLANAR FOLDED TRANSMISSION LINE LOOP ANTENNA

摘要

PURPOSE: A planar folded transmission line loop antenna is provided to improve RFID(Radio Frequency Identification) tag recognition performance by improving radiation characteristics of an antenna. CONSTITUTION: A rectangular printed circuit board(33) is provided. A radiator(32) is formed on the printed circuit board. The radiator radiates electric waves of an RFID reader in an UHF band. A feed terminal(31) is formed at the center of a mesh-type net structure of the printed circuit board. The feed terminal is connected to a coaxial cable for supplying power.
