Circuit for suppression of spurious modes on planar transmission lines |
摘要 |
Electrodes are formed on the upper and under faces of a dielectric plate. For example, plural fundamental patterns having four ports and a quadrangular shape are arranged thereon. A strip conductor of a two-port circuit is determined so that adjacent two-port circuits of the respective fundamental patterns have a band-stop filter characteristic for spurious modes. <IMAGE> <IMAGE>
