| 摘要 |
The present invention relates to a microwave device which comprises a number of parallell-plate resonators which comprises at least one dielectric substrate with first and second plates arranged on either side thereof. At least one of said first and second plates of each of a number of said parallell-plate resonators is patterned/formed in such a way, or in other words comprises current interrupting means (2A, 2B, 2C, 2D), such that the current lines of at least one undesired mode are interrupted at their maxima to suppress said undesired mode(s). The invention also relates to a method of interrupting undesired modes in a microwave device comprising a number of parallell-plate resonators. <IMAGE> |
