國立中山大學
2012/01/11
一種耦合式寬頻偶極天線,包含:一介質基板、一第一輻射部、一第二輻射部及一耦合部。該介質基板具有一第一表面及一第二表面;該第一輻射部位於該介質基板之第一表面;該第二輻射部,位於該介質基板之第一表面,且該第二輻射部具有一第一饋入點,該第二輻射部與該第一輻射部形成該偶極天線之兩臂;該耦合部大致為一長條形金屬片,位於該介質基板之第二表面上,其一端為一第二饋入點,面向該第二輻射部,與該第一饋入點具有一特定間距,其另一端則朝向該第一輻射部之方向延伸。 A coupled-fed broadband dipole antenna comprises a substrate, a first radiating portion, a second radiating portion and a coupling portion. The substrate has a first surface and a second surface. The first radiating portion and the second radiating portion are located on the first surface and are the two arms of the dipole antenna. The second radiating portion has a first feeding point. The coupling portion is substantially a long metal strip and is located on the second surface. One end of the coupling portion is the second feeding point, which faces the second radiating portion; the other end of the coupling portion is extended in the direction of the first radiating portion. The first feeding point and the second feeding point are separated by a predefined distance.
