A dual-band three-dimensional (3D) antenna is disclosed, which comprises: a first radiation unit (11); a resonant extension unit (12), being disposed not on the same plane with the first radiation unit; a feeder unit (13), coupled to the first radiation unit while allowing an opening (18) to be formed at a position between the feeder unit and the first radiation unit; a connection unit, coupled to a substrate (17) and the feeder unit while allowing an obliquely extending unit (15) to be formed at a position between the connection unit and the feeder unit; and a second radiation unit (16), coupled to the resonant extension unit. |
