Dual-band inverted-F antenna
First Claim
1. A dual-band inverted-F antenna, comprising:
- a ground substrate, which has a ground surface and a through hole;
a radiating body, which is a flat plate and at least has a first side, a second side, a third side, and a split, wherein the first side and the second side form a first included angle, while the second side and the third side form a second included angle, the third side is disposed opposite to the first side, and the split is positioned from the first side to the second side;
a first ground part, which is extended along the third side with a first distance away from the second side, and electrically connects to the ground surface;
a second ground part, which is sheet-shaped, is extended along the second side with a second distance away from the first side, and electrically connects to the ground surface; and
a feed point passing through the through hole and electrically connected, to the first side of the radiating body, wherein a third distance is set between the feed point and the second side.

Abstract
A dual-band inverted-F antenna includes a ground substrate, a radiating body, a first ground part, a second ground part and a feed point. The ground substrate has a ground surface. The radiating body at least has a first side, a second side, a third side, and a split. The first side and the second side form a first included angle, while the second side and the third side form a second included angle. The third side is disposed opposite to the first side, and the split is positioned from the first side to the second side. The first ground part is extended along the third side with a first distance away from the second side. The second ground part is extended along the second side with a second distance away from the first side. A third distance is set between the feed point and the second side.
