摘要：This arrangement is intended to reduce the number of aerial leads (waveguides)necessary for a dual-band or multi-band aerial. For this purpose the invention providesfor a wideband polarisation separator (2) which can be switched in at the aerial exciter of adual-band or multi-band aerial for all frequency bands, which is connected via twowaveguides (3) of suitable type each for the same polarisation of the microwavefrequency bands, each with a frequency separator (4, 5) for each polarisation.
