An antenna device includes a first dielectric substrate made of a high dielectric coefficient material, a plurality of first contact pads fastened on a periphery of a top surface of the first dielectric substrate, a plurality of second dielectric substrates made of the high dielectric coefficient material, and a plurality of Yagi-Uda antennae respectively disposed on top surfaces of the second dielectric substrates. The second dielectric substrates are fastened on the first dielectric substrate. Each of the Yagi-Uda antennae has a drive, and a plurality of directors disposed in an outside position of the drive and spaced from an outer side of the drive. The directors are shorter than the drive, and the directors are arranged along a direction of being gradually away from the drive and gradually become shorter. An inner side of the drive defines a signal feed point.

Antenna device

A multi-band antenna includes a base portion, a high-frequency radiating portion, a feeding portion and a low-frequency radiating portion. The base portion has a first transverse edge and a second transverse edge parallel to and opposite to the first transverse edge. The high-frequency radiating portion includes an inductance portion, a first extending portion, a second extending portion and a third extending portion. One side of a bottom of the feeding portion defines a feeding point. The low-frequency radiating portion has a bending portion, a coupling portion and an auxiliary portion. The base portion, the high-frequency radiating portion, the coupling portion and the auxiliary portion are coplanar. The base portion, the high-frequency radiating portion, the coupling portion and the auxiliary portion together with the bending portion are located in two perpendicular planes.

Multi-band antenna

An antenna structure includes an antenna portion having an antenna defining a feeding point and a grounding point, and a grounding portion electrically connecting with the grounding point of the antenna. The grounding portion defines a basic board. The basic board is bent upwardly from edges thereof to form a first extending portion. The first extending portion is bent inwardly from a top edge thereof to form a second extending portion approximately paralleling with the basic board. Through the first and second extending portions, the area of the grounding portion is extended. And the electric field is widely distributed all over the whole grounding portion including the basic board and the first and second extending portions to decrease the SAR of the antenna.
