Abstract:
A waveguide arrangement (1) for coupling a plurality of modules (5) to a source. The waveguide arrangement (1) comprises a continuous waveguide (10) configured for guiding a signal provided by the source and a plurality of interfaces (15), each interface (15) being associated with one of the plurality of modules (5) and being configured for transferring a part of the source signal guided in the waveguide (10) to its associated module (5). The continuous waveguide (10) allows the source signal to propagate continuously without needing reconversion at each module (5). As such, the waveguide arrangement (1) loses less power and is more efficient. Moreover, each module (5) receives the exact same input signal which improves the coherence between the modules (5).
