BAND-REJECTION FILTER |
| 摘要 |
The present invention relates to a band-rejection filter comprising, on a substrate with a ground plane, three printed line sections or “stubs” open circuit at one of their extremities, called first extremities, and first and second printed transmission lines connected in series between an input terminal and an output terminal and connecting between each other the other extremities, called second extremities, said stubs, each of said first and second transmission lines being inserted between the second extremities of two stubs, said stubs being dimensioned to reject a first frequency band. According to the invention, an open circuit stub is inserted in at least one of said first and second printed transmission lines to reject a second frequency band. |

1. Band-rejection filter comprising, on a substrate with a ground plane, three printed line sections or “stubs” open circuit at one of their extremities, called first extremities, and first and second printed transmission lines connected in series between an input terminal and an output terminal and connecting between each other the other extremities, called second extremities, of said stubs, each of said first and second transmission lines being inserted between the second extremities of two stubs, said stubs being dimensioned to reject a first frequency band,
wherein an open circuit stub is inserted in at least one of said first and second printed transmission lines to reject a second frequency band. |
