Abstract (en)
[origin: EP0224917A1] 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 provides for a wideband polarisation separator (2) which can be switched in at the aerial exciter of a dual-band or multi-band aerial for all frequency bands, which is connected via two waveguides (3) of suitable type each for the same polarisation of the microwave frequency bands, each with a frequency separator (4, 5) for each polarisation. <IMAGE>
