C SHAPED MEANDER LINE ANTENNA WITH CONICAL RADIATION PATTERN FOR THE RFID TAG APPLICATIONS

摘要

PURPOSE: An RFID(Radio Frequency Identification) tag antenna is provided to miniaturize an antenna by forming a horizontal radiation element into a meander line which is structured to a C shape. CONSTITUTION: An RFID tag antenna comprises a ground plane(G), a dielectric, and a radiation element(100). The dielectric has a predetermined dielectric constant. The radiation element comprises a first and a second lateral elements(111,112), a first and a second vertical devices(121,122), and a feeding line(FL), and a meander device(130). The first and the second lateral element are attached on the dielectric in parallel. The first and the second vertical device are extended from one end of the first and the second lateral element to the ground plane. The feeding line is extended from the central part of the second lateral element to the ground plane. The meander device is extended from the other end of the first and the second lateral element.
