Radio frequency filter comprising helix resonators |
| 摘要 |
<p>The invention relates to a radio frequency filter comprising at least two helix resonators (HX1 - HX2) placed at a distance from each other, each of which is wound of a metal wire into a cylindrical coil. A conductor (MLIN2), preferably a microstrip line, runs between two neighboring resonators and is provided at a distance (d1, d2) from each of the resonator coils so that one part (3) of it is electromagnetically connected to one resonator (HX1) and the other part (4) is electromagnetically connected to another resonator (HX2). <IMAGE></p> |
