技術說明

本發明之一種多頻單極天線，係包含：一接地面、一介質基板及一金屬輻射元件。該介質基板位於該接地面之一邊緣處，並大致與該接地面平行向外延伸；該金屬輻射元件位於該介質基板之一表面上，並包含：一第一輻射部，具有一短路點；一短路部，其一端電氣連接至該第一輻射部之該短路點，另一端則電氣連接至該接地面；一第二輻射部，其一端為天線饋入點；及一耦合部，包含：一第一耦合部，其一端電氣連接至該第一輻射部；及一第二耦合部，其一端電氣連接至該第二輻射部，並與該第一耦合部具有一耦合間距。 The multiband monopole antenna comprising a ground plane, a substrate, and a radiating metal element. The substrate is located at about one edge of the ground plane and extended in the opposite direction of the ground plane. The radiating metal element comprising a first radiating portion, a second radiating portion, a shorting portion, and a coupling portion is located on one surface of the substrate. The first radiating portion includes a shorting point. One end of the shorting portion is connected to the shorting point, and the other end of the shorting portion is connected to the ground plane. One end the second radiating portion is a feeding point for the antenna. The coupling portion comprises a first coupling portion and a second coupling portion. One end of the first coupling portion is connected to the first radiating portion. One end of the second coupling portion is connected to the second radiating portion and has a coupling gap with the first coupling potion.
