A three-dimensional antenna includes a substrate, a radiator, a second radiator, a signal feeding element, and a grounding element. The radiator is installed on the substrate. The radiator includes a first child radiator and a second child radiator. The first child radiator has a first end and a second end. The second child radiator has a first end and a second end, wherein the second end of the second child radiator is coupled to the second end of the first child radiator. The second radiator is coupled to the radiator. The signal feeding element is coupled to the first end of the first child radiator. The grounding element is coupled between the substrate and the first end of the second child radiator. The first child radiator and the second child radiator form an inverted V-shape installed on the substrate.
