Abstract
An antenna device having ultra wide bandwidth characteristics includes: a dielectric substrate having first and second surfaces that are opposite to each other in a normal direction; a radiating element formed on the first surface of the dielectric substrate and defining an axis perpendicular to the normal direction; and a grounding element formed on the second surface of the dielectric substrate and cooperating with the radiating element to define first and second imaginary slots in the dielectric substrate. The first and second imaginary slots extend in the normal direction from the first surface to the second surface of the dielectric substrate, and are respectively disposed at two opposite sides of the axis.

An antenna device having ultra wide bandwidth characteristics, comprising:
- a dielectric substrate having first and second surfaces that are opposite to each other in a normal direction;
- a radiating element formed on said first surface of said dielectric substrate, defining an axis perpendicular to said normal direction, and having a peripheral edge that has an inner portion;
- and
- a grounding element formed on said second surface of said dielectric substrate and having a peripheral edge that has an inner portion facing toward said inner portion of said peripheral edge of said radiating element;
- wherein said inner portion of said peripheral edge of said grounding element cooperates with said inner portion of said peripheral edge of said radiating element to define first and second imaginary slots in said dielectric substrate, said first and second imaginary slots extending in said normal direction from said first surface to said second surface of said dielectric substrate, and being respectively disposed at two opposite sides of said axis.
