Three-dimensional antenna and related wireless communication device

A three-dimensional antenna, comprising:

• a substrate, having a first end and a second end;
• a radiator, comprising:
• a first child radiator, having a first end and a second end;
• and
• a second child radiator, having a first end and a second end, the second end of the second child radiator coupled to the second end of the first child radiator;
• a grounding element, coupled between the first end of the substrate and the first end of the second child radiator to form a designated spacing by bending the substrate;
• and
• a signal feeding element, coupled to the first end of the first child radiator;
• wherein the first child radiator and the second child radiator form an inverted V-shape installed on the substrate.

A wireless communication device with three-dimensional antennas, the wireless communication device comprising:

• a system circuit;
• and
• a plurality of three-dimensional antennas coupled to the system circuit, each three-dimensional antenna comprising:
• a substrate;
• a radiator, installed on the substrate, the radiator comprising:
• a first child radiator, having a first end and a second end;
• and
• a second child radiator, having a first end and a second end, the second end of the second child radiator coupled to the second end of the first child radiator;
• a second radiator, coupled to the radiator;
• a signal feeding element, coupled to the first end of the first child radiator;
• and
• a grounding element, coupled between the substrate and the first end of the second child radiator;
• wherein the first child radiator and the second child radiator form an inverted V-shape installed on the substrate.
