- the microwave line can also generally be designed such that it not only runs in a straight line, but also at least in sections is curved. As a result, the microwave line can follow a shape of a non-planar wall region, for example it can also be routed around corners.
- the microwave line can be connected at its end on the cooking chamber side to a dedicated feed device such as an antenna, in particular a rotatable antenna. Alternatively, the microwaves can be fed into the cooking space directly from the microwave line.
