技術說明

本發明係關於一種耦合式饋入行動通訊天線，主要包含：一電路板、一接地面及一天線元件。該天線元件位於該電路板之無接地面區間上。該天線元件並包含：一輻射金屬部及一饋入部。該輻射金屬部並包含：一第一輻射金屬部及一第二輻射金屬部。該饋入部並包含：一第一金屬元件、一第二金屬元件及一短路金屬元件。該第一金屬元件其一端電氣連接至該輻射金屬部；該第二金屬元件，具有一饋入點，該饋入點為天線之饋入點，且該第二金屬元件與該第一金屬元件之間具有一特定間距；該短路金屬元件其一端連接至該第一金屬元件，另一端則連接至該接地面。 The present invention is related to a coupled-fed mobile communication antenna. The antenna comprises a circuit broad, a ground plane, and an antenna element. The antenna element is located on the no-ground region of the circuit board. The antenna element consists of a radiating metal portion and a feeding portion. The radiating metal portion comprises a first radiating metal portion and a second radiating metal portion. The feeding portion comprises a first metal element, a second metal element, and a shorting metal element. One end of the first metal element is electrically connected to the radiating metal portion. The second metal element has a feeding point for the antenna, and there is a predetermined distance between the second metal element and the first metal element. One end of the shorting metal element is connected to the first metal element, and the other end of the shorting metal element is connected to the ground plane.
