A multi-band dipole antenna includes spaced part first and second radiator sections, first and second mirroring radiator sections, and a balun, which are disposed on a substrate. The first mirroring radiator section is symmetrically disposed with respect to the first radiator section and is spaced apart from the first radiator section. The first radiator section and the first mirroring radiator section cooperate to resonate in a first frequency band. The second radiator section cooperates with the second mirroring radiator section to resonate in a second frequency band.
