Abstract (en)
[origin: EP0029276A1] Microwave filter formed by one or more transverse partitions mounted behind each other in a waveguide (1), and provided with parallel slots (2) of different lengths. The length of the longest slot is equal to about half the wavelength of the centre frequency of the pass band, whereas the lengths of the other slots are determined for each partition by the largest possible attenuation in a stop band.
