技術說明

本發明係一種耦合式饋入多頻天線，主要包含：一接地面及一輻射金屬元件。該輻射金屬元件位於該接地面之ㄧ邊緣附近，大致平行朝外延伸。該輻射金屬元件並包含：一輻射部、一饋入部及一短路部。該饋入部並包含：一第一饋入部及一第二饋入部。該第一饋入部具有一饋入點，該饋入點為天線之饋入點；該第二饋入部之一端連接至該輻射部，且該第二饋入部與該第一饋入部之間具有一特定間距；該短路部之一端電氣連接至該輻射部，另一端電氣連接至該接地面。 The present invention is related to a coupled-fed multiband antenna. The antenna comprises a ground plane and a radiating metal element. The radiating metal element is located near one edge of the ground plane and extended outward, toward the opposite direction of the ground plane. The radiating metal element comprises a radiating portion, a feeding portion, and a shorting portion. The feeding portion further consists of a first feeding portion and a second feeding portion. The first feeding portion has a feeding point for the antenna. One end of the second feeding portion is connected to the radiating portion, and there is a predetermined distance between the second feeding portion and the first feeding portion. One end of the shorting portion is electrically connected to the radiating portion, and the other end is electrically connected to the ground plane.
