技術摘要: |
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 for transmitting a wireless signal is provided. The coupling device includes a substrate, a ground layer and a feed conductor. The substrate includes a first surface and a second surface opposite to the first surface. The ground layer is disposed on the second surface having a circular opening, and the circular opening has an opening edge and an opening center. The feed conductor extends on the first surface, including a conductive portion and a feed portion connected thereto. The feed portion corresponds to the circular opening, wherein the opening center is on a base line, a radial line is formed between the opening center and the opening edge, a radial distance is formed on the radial line between the opening edge and the feed portion, and a length of the radial distance varies with an angle between the radial line and the base line.
