CIRCULAR CYLINDRICAL DIELECTRIC ROD WAVEGUIDE

Abstract

Tbe propagation   characteristics,  such  as,  propagation constant, guide wave length, radial field spread, division of  power  as  a  function  of  the  diameter  and  dielectric  constant  of  a  circular cylindrical  rod dielectric  guide  excited  in H01, E01 and HE11 modes are studied. Tbe  study  of  scattering  coefficients of  the  H01 – H11 mode transducer  which is  used  to  excite  the  guide  in  HE11  mode.  leads  to  its  representation as an  equivalent Tee-  network.  The  insertion  loss  and  launching  efficiency  of  the  mode  transducer  has  been  evaluated.  The  scattering  coefficients,  impedance and attention characteristics of the dielectric guide excited in HE11 mode are also studied.
