Abstract
A dual-band inverted-F antenna is disclosed. This dual-band inverted-F antenna comprises: a substrate with a first surface and a second surface; a ground plane located on the second surface of the substrate; a first radiating metal line located on the first surface of the substrate; a second radiating metal line located on the first surface of the substrate; a feeding line located on the first surface of the substrate and the feeding line connected with the middle positions of the first radiating metal line and the second radiating metal line for feeding signal; a connecting line located on the first surface of the substrate and used to connect with the first radiating metal line and the second radiating metal line at the same time; and a common shorting metal pin used to short-circuit the first radiating metal line and the second radiating metal line to the ground plane. There is a valuable implementation in industrial field because the dual-band inverted-F antenna of the present invention can be operated in two separate bands, and can be printed on a microwave substrate, which makes it easy to integrate with other associated microwave circuitry.
