Mobile Communication Device and Antenna Structure Therein
First Claim
1. A mobile communication device having an antenna structure, the antenna structure comprising:
- a grounding element; and
an antenna element, disposed in one side of the grounding element, the antenna element comprising;
an antenna ground plane, electrically connected to the grounding element;
a radiation portion, disposed on a substrate, the radiation portion comprising;
a signal feeding point, disposed on one end close to the grounding element; and
a first radiation section and a second radiation section, wherein the first and second radiation sections are connected to the signal feeding point, and open ends of the first and second radiation sections are extended toward the same direction; and
a shorted radiation portion, disposed on the substrate, a first end of the shorted radiation portion being electrically connected to the antenna ground plane, and a second end of the shorted radiation portion being an open end, wherein there is a coupling gap between a designated section of the shorted radiation portion close to the first end and the radiation portion, and through the coupling gap, the shorted radiation portion is capacitively excited by radiation portion and generates at least one resonant mode to increase an operating bandwidth of the antenna element;
wherein the antenna element is a three-dimensional structure, and the antenna ground plane and the radiation portion are located on different planes of the three-dimensional structure.

Abstract
A mobile communication device having an antenna structure includes a grounding element and an antenna element. The antenna element includes an antenna ground plane, a radiation portion, and a shorted radiation portion, wherein the antenna ground plane is grounded to the grounding element. The radiation portion includes a signal feeding point, a first radiation section, and a second radiation section. First and second radiation sections are connected to the signal feeding point, and are extended toward the same direction. First end of the shorted radiation portion is electrically connected to the antenna ground plane, and second end is left open. There is a coupling gap between a designated section of the radiation portion close to the first end and the shorted radiation portion. Through the coupling gap, the shorted radiation portion is capacitively excited by the radiation portion and generates at least one resonant mode to increase antenna'"'"'s operating bandwidth.
