Abstract
The paper presents the results of the design and investigation of a coaxial-to-waveguide transducer (CWT) for waveguides with a reduced height of a narrow wall widely used in radio electronic systems, where the mass and size requirements are critical. The design of the CWT is based on the use of a matching cavity located near the short-circuited wall of the waveguide. The data of an experimental study of five prototypes of a CWT for a waveguide with a cross section of 61×10 mm are presented. In the frequency range 2.9−4.5 GHz, the insertion loss of a CWT is not less than −0.12 dB, and the return loss is not more than −20 dB. The characteristics of the CWT allow using them for testing the paths and equipment of space and terrestrial communication systems.
