A multi-beam antenna array system according to an exemplary embodiment of the present disclosure includes: a grounding surface; a plurality of multi-beam antennas which each includes a dielectric substrate and a radiating part formed on the dielectric substrate so as to radiate electromagnetic waves, and is disposed above the grounding surface so as to be spaced apart from each other; and a feed circuit which is formed on a lower portion of the grounding surface, and supplies electric power to the plurality of multi-beam antennas so that the electromagnetic waves are radiated in different directions from the plurality of multi-beam antennas.

Multi-beam antenna and multi-beam antenna array system including the same

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.
