Polarisation branch for two different frequency bands

摘要

The arrangement has a hollow conductor section receiving two mutually perpendicular, linearly polarised waves per frequency band. Each band has two hollow conductors connected to the hollow conductor section. The higher band conductors have two arms (18-21). At both connection points (11,12) for the two arms the broad flat sides are in direct contact and their ends are flushed together for connecting each hollow conductor. One (19,21) of each pair of arms is twisted through 180 degrees
