Abstract
A slot antenna located on a substrate with a first surface and a second surface opposite to the first surface includes a feeding portion and a radiating portion. The feeding portion is located on the first surface of the substrate to feed electromagnetic signals. The radiating portion is located on the second surface of the substrate and defines a sector-shaped slot, a first rectangle-shaped slot, a second rectangle-shaped slot, and a third rectangle-shaped slot, wherein the sector-shaped slot is defined by a first semidiameter, a second semidiameter, and an arc connected one by one.
Claims8
A slot antenna located on a substrate having a first surface and a second surface opposite to the first surface, the slot antenna comprising:
- a feeding portion located on the first surface of the substrate, to feed electromagnetic signals;
- and
- a radiating portion located on the second surface of the substrate and defining a sector-shaped slot, a first rectangle-shaped slot, a second rectangle-shaped slot, and a third rectangle-shaped slot, wherein the sector-shaped slot is defined by a first semidiameter, a second semidiameter, and an arc connected one by one;
- wherein the first rectangle-shaped slot, the second rectangle-shaped slot, and the third rectangle-shaped slot are commonly extended away from a center of the sector-shaped slot, and the second rectangle-shaped slot and the third rectangle-shaped slot are substantially symmetrical based on a symmetry axis of the sector-shaped slot;
- wherein a projection of the feeding portion on the second surface of the substrate overlaps with the first rectangle-shaped slot.
