Abstract (en)
[origin: CA3090193A1] A circuitry for feeding an antenna structure includes an input for LHCP signals, an input for RHCP signals as well as four antenna outputs. In addition, the circuitry includes first, second and third quadrature hybrids as well as at least two delay lines. The first quadrature hybrid is coupled, on the input side, to the first and second inputs and is coupled, on the output side, to the second and third quadrature hybrids. The second quadrature hybrid is coupled, on the output side, to two of the four antenna outputs, the third quadrature hybrid being coupled, on the output side, to two further ones of the four antenna outputs. The at least two delay lines are arranged at two of the four antenna outputs.
