DOUBLE-FREQUENCY BRANCH DIRECTIONAL COUPLER |
摘要 |
A double-frequency branch directional coupler comprises a dielectric substrate, on one side of which a metal screen is positioned, on the other side – two main microstrip lines interconnected via sections of line-loop in the form of microstrip lines, to the middle of each the auxiliary section of microstrip line is connected, whose unconnected end is connected to the screen through a metalized hole. If two auxiliary lengths are applied, a ratio of lengths of main microstrip line/loop line is 1:2. |
