OVAL CORRUGATION HORN CONTAINING DIELECTRIC SUBSTANCE

摘要

PURPOSE:To increase the degree of freedom for space of installation between a corrugation horn and another feed horn by burying a dielectric substance having a specific dielectric constant larger than 1 into a corrugation groove at the side of a short axis in order to decrease effectively the depth of said corrugation groove. CONSTITUTION:A dielectric substance 10 having a specific dielectric constant larger than ''1'' is buried into a corrugation groove 9 at the side of a short axis 6. Here the specific dielectric constant is referred to as epsilon and therefore the depth (t) of the groove 9 can be set effectively at t/epsilon<1/2> owing to the presence of the substance 10. In other words, the depth (t) can be reduced effectively. This reduces the minimum space with another feed horn and can increase the degree of freedom for space of installation of a corrugation horn.
