Abstract
Provided is a compact dipole antenna for a radio frequency identification (RFID) tag. The antenna includes a substrate, a dipole radiator including a first dipole element and a second dipole element, in each of which a first meander line formed in a meandering shape and an arm configured of a triangular pattern which is an end connected to the first meander line, are arranged to face each other, wherein the first and second dipole elements are arranged on the substrate to be perpendicular to each other, and an impedance matcher, which includes a second meander line formed in a meandering shape, is formed at a point at which the first and second dipole elements are perpendicular to each other, and performs an impedance matching between the antenna and an RFID tag chip through the second meander line.
