Abstract
Disclosed is a dual-frequency antenna including a dielectric carrier plate, a first radiator, a second radiator, a coupling radiator and a coaxial cable. The first radiator, the second radiator and the coupling radiator are disposed on a first surface of the dielectric carrier plate, and the coupling radiator is located between the first radiator and the second radiator and is spaced apart from the first radiator and the second radiator respectively. The coaxial cable includes an inner conductor, a first insulating layer covering part of the inner conductor, an outer conductor covering part of the first insulating layer, and a second insulating layer covering part of the outer conductor. The exposed inner conductor is electrically connected to the first radiator. The exposed outer conductor is electrically connected to the second radiator. Therefore, the dual-frequency antenna generates a first resonance mode and a second resonance mode with different center frequencies.
