1. A waveguide device, comprising:
a base element having a first surface side and an oppositely situated second surface side; and
a plurality of waveguide elements that conduct electromagnetic waves, the elements being arranged between the first surface side and the second surface side, the first surface side having a first waveguide opening arrangement and, the second surface side having a second waveguide opening arrangement different from the first waveguide opening arrangement;
wherein the base element includes support elements configured to adapt a strain in a first plane including the first surface side to a strain in a second plane including the second surface side, the adaptation reducing a deformation of the waveguide device,
wherein the first and second surface sides are arranged parallel to each other and opposite with respect to a first direction, and
wherein the support elements include at least one compensation recess penetrating the second surface side and acting outside of a wave transmission of the electromagnetic waves, the recess being located, with respect to the first direction, opposite a waveguide element on the first surface side.
