Abstract

1. Pass band filter of dielectric resonator type, comprising a waveguide (1) operating below its cut-off frequency, an input antenna (Ae ) and an output antenna (As ) respectively disposed at the two ends of the guide, and n resonators (n positive integer) (R1 -R4 ) disposed in series inside the guide, characterized in that, in a manner to have the resonators oscillate in the TM011 mode and to excite a TM mode within the guide the cut-off frequency of which exceeds that of the mode TM011 of the resonators, the dimensions of the transverse section of the guide are of the order of 2.5 times the transverse dimensions of the resonators, the resonators being substantially disposed along the longitudinal axis (XX) of the guide and the antennas being disposed in the propagation sense in the guide.
