Abstract (en)
[origin: WO2009084050A1] A slot antenna having a single -ridge waveguide (13) with a top broadwall (12) and a plurality of radiant elements (5). The radiant elements are formed on the top broadwall (12) and are configured to radiate and receive circularly- polarized waves. Each radiant element (5) is formed by two slots (11) which are arranged at 90 to each other, are non-overlapping, extend on opposite sides with respect of the broadwall axis A and are spaced apart from each other by a mutual distance in the range of lambdag/4±20%, wherein lambdag is a nominal guide wavelength.
