技術說明

一種耦合裝置，包括一基板、一接地層以及一饋入導體。基板包括一第一表面以及一第二表面。接地層設於該第二表面，該接地層包括一圓形開口，該圓形開口包括一開口邊緣以及一開口圓心。饋入導體延伸於該第一表面，該饋入導體包括一傳導部以及一饋入部，該傳導部連接該饋入部，該饋入部對應該圓形開口，其中，該開口邊緣與該饋入部之間具有一徑向間距，該開口圓心位於一基準線之上，該基準線平行於該傳導部的延伸方向，該開口圓心與該開口邊緣之間具有一徑向線，該徑向間距的長度隨著該徑向線與該基準線之間的夾角而逐漸變化。 A coupling device comprises a substrate, a ground layer and a feed conductor. The substrate comprises a first surface and a second surface. The ground layer is disposed on the second surface comprising a circular opening. The circular opening comprises an opening edge and an opening center. The feed conductor extends on the first surface comprising a conductive portion and a feed. The conductive portion is connected to the feed. The feed corresponds to the circular opening. A radial gap is formed between the opening edge and the feed. The opening center is located on a base line. The base line is parallel to an extension direction of the conductive portion. A radial line is formed between the opening edge and the opening center. The radial gap varies with an included angle between the radial line and the base line.
