Abstract
A slot antenna device including a substrate, a metal layer and a feeding element is provided. The substrate has a first surface and a second surface opposite to the first surface. The metal layer is disposed on the first surface, and includes a slot extending along a first direction. The feeding element is disposed on the second surface, and extended along a second direction, where the first direction is perpendicular to the second direction. A length of the slot is a sum of each quarter wavelength of at least three frequency bands, so that the slot antenna device is operated at the at least three frequency bands. A projection of the feeding element on the first surface crosses the slot, so that the slot is divided into a first section and a second section, where a length of the first section is equal to a length of the second section.
