Design of Tri-frequency Mode Transducer

V. K. Singh, S. B. Chakrabarty, S. B. Sharma


This paper presents the design, modal analysis and measured results of a mode transducer operating at three frequency bands at 18.7, 23.8 and 36.5 GHz. In this device, cascaded circular waveguides excited by rectangular waveguides through co-axial line fed probes have been used. Mechanisms of cascading of waveguides have been investigated in order to achieve the intended performance at all the three frequency bands. The simulated results of the tri-frequency mode transducer are compared with the measured results.
