Mobile device supporting wideband operation

A mobile device supporting wideband operations, comprising:

• a first radiation element, having a feeding point;
• a second radiation element, coupled to the first radiation element;
• a third radiation element, coupled to the first radiation element, wherein the third radiation element and the second radiation element substantially extend in opposite directions;
• a fourth radiation element, wherein the first radiation element is coupled through the fourth radiation element to a ground voltage;
• a fifth radiation element, coupled to the fourth radiation element, wherein the fifth radiation element is adjacent to the second radiation element;
• a sixth radiation element, coupled to the ground voltage, wherein the sixth radiation element is adjacent to the first radiation element and the third radiation element;
• and
• a seventh radiation element, coupled to the sixth radiation element, wherein the seventh radiation element extends away from the third radiation element;
• wherein an antenna structure is formed by the first radiation element, the second radiation element, the third radiation element, the fourth radiation element, the fifth radiation element, the sixth radiation element, and the seventh radiation element.
