Abstract
The present invention relates to a mechanical compensating device for a waveguide (). More precisely, the present invention provides a technology for ensuring phase stability in a waveguide () subject to expansions and contractions owing to temperature changes. To do this, actuators, which may consist of pairs of prongs (--), connected to longitudinal ribs () cut in the body of the waveguide () and integral therewith, cause, because of a large difference between the respective coefficients of thermal expansion of the waveguide () and of the actuators, a rotation of the longitudinal ribs () about themselves, deforming the short sides () of the waveguide () when said waveguide () expands or contracts according to the changes in temperature.
