Abstract (en)
[origin: EP2658032A1] The guide has a grid (21) placed in vicinity of an opening (14) and comprising a frame (210) surrounding strips (211-213) extending longitudinally and continuously from a small side (250a) of the frame to another small side (250b) of the frame so as to form a linear polarization filter attenuating a cross-polarization component of electric field of electromagnetic wave. The component is orthogonal to an axis (y) orthogonal to a longitudinal axis (z). The strips include corrugations (22) sized and positioned to reinforce attenuation of the component. An independent claim is also included for a method for testing a radiofrequency equipment.
