Antenna structure

An antenna structure, comprising:

• a ground element;
• a feeding radiation element, having a feeding point;
• a connection radiation element;
• a coupling radiation element, coupled through the connection radiation element to the feeding radiation element;
• a first shorting radiation element, wherein the coupling radiation element is coupled through the first shorting radiation element to a first grounding point on the ground element;
• and
• a second shorting radiation element, wherein the feeding radiation element is coupled through the second shorting radiation element to a second grounding point on the ground element;
• wherein a loop structure is formed by the ground element, the connection radiation element, the first shorting radiation element, and the second shorting radiation element;
• wherein the coupling radiation element has a first edge, a second edge, and a third edge, and wherein the third edge is positioned between the first edge and the second edge;
• wherein the antenna structure covers a low-frequency band, a first high-frequency band, a second high-frequency band, and a third high-frequency band;
• wherein a first resonant path is formed along the feeding radiation element, the connection radiation element, the first edge, the third edge and the second edge of the coupling radiation element, the first shorting radiation element, and the ground element, and wherein the first resonant path is excited to generate the low-frequency band and the second high-frequency band.
