摘要： Certain examples provide an apparatus (100) comprising: first, second and third waveguide ports (101, 102, 103) for supporting respective first, second and third signals (101s, 102s, 103s). The first, second and third waveguide ports are respectively configured to have first, second and third frequency bands of operation, wherein the second and third frequency bands of operation are sub-bands of the first frequency band of operation, and wherein the third frequency band of operation is higher than the second frequency band of operation. The apparatus also comprises a waveguide structure (104), disposed between the first waveguide port and the second and third waveguide ports, configured to: split, in the frequency domain, the first signal into the second and third signals, and/or combine, in the frequency domain, the second and third signals into the first signal. The waveguide structure comprises an asymmetric cross-sectional shape defining: first and second aperture regions (104a1, 104a2) having respective first and second extents, wherein the second extent is less than the first extent. The waveguide structure is arranged relative to the second and third waveguide ports such that: the third waveguide port is predominantly adjacent the first aperture region, and the second waveguide port is predominantly adjacent the second aperture region.

摘要： An apparatus comprising:
a first waveguide port configured to support first signals having a first polarisation state;
a second waveguide port configured to support second signals having a second polarisation state orthogonal to the first polarisation state;
a third waveguide port configured to support combined signals comprising a first signal component having the first polarisation state and a second signal component having the second polarisation state;
a waveguide structure, disposed between the first waveguide port, the second waveguide port and the third waveguide port, configured to:
split a combined signal received via the third waveguide port into first and second signal components and to provide the first signal component to the first waveguide port and the second signal component to the second waveguide port,
and/or
combine a first signal received via the first waveguide port and a second signal received via the second waveguide port into a combined signal and to provide the combined signal to the third waveguide port;
wherein an end portion of the first waveguide port, adjacent the waveguide structure, comprises, at a first side, a first curved portion having a first radius of curvature, r1, and, at a second side, a second curved portion having a second, different radius of curvature, r2.
