    • PURPOSE: A transmission line filter structure using a duel spur-line is provided to reduce a manufacturing cost and a miniaturization of the filter by embodying the filter blocking with forming a duel spur line on the transmission line. CONSTITUTION: A first spur-line(400) is formed on a transmission line(300). The first spur-line is locates on one side in parallel with a length direction of the transmission line. A second spur-line(500) is located on the other side in parallel with the length direction of the transmission line. The second spur-line includes a stub opened to the stub of the first spur-line with opposing direction. The stub of the first and the second spur-line is parallel with the length direction of the transmission line.
    • 目的:提供使用决斗支线的传输线滤波器结构,以通过在传输线上形成决斗支线来实现滤波器阻挡来降低制造成本和滤波器的小型化。 构成:在传输线(300)上形成第一支线(400)。 第一支线与传输线的长度方向平行地位于一侧。 第二支线(500)位于与传输线的长度方向平行的另一侧上。 第二支线包括一个与第一支线相对的方向开口的短截线。 第一和第二支线的短截线与传输线的长度方向平行。
