Converter for satellite broadcast reception that secures isolation between vertically polarized waves and horizontally polarized waves |
摘要 |
Each of a first minute radiation pattern and a second minute radiation pattern is provided on a first circuit board so as to be inclined electrically by about 45° from the respective axial lines of a first probe for vertically polarized waves and a second probe for horizontally polarized waves. The first minute radiation pattern is approximately perpendicular to a phase conversion portion of a first dielectric feeder, and the second minute radiation pattern is approximately parallel with a phase conversion portion of a second dielectric feeder. The phase conversion portion of the first dielectric feeder is longer than that of the second dielectric feeder.
