Coupled line and method of producing the same |
摘要 |
In a coupled line, microstrip lines are formed so as to be arranged with a spacing that is narrower than the smallest possible space that is obtainable with a conventional electrode forming process, on a top side thereof spaced away from a dielectric substrate. The microstriplines have a trapezoid-shaped cross-section with the narrower major surface at the bottom, in contact with the dielectric substrate. Such formation makes it possible to strengthen the coupling between the microstrip lines, and to reduce the conductor loss of the microstrip lines. |
