Broad-Band Coaxial-to-Waveguide Transition

The C-band adapter for matching standard coaxial line and rectangular waveguide with reduced height is simulated numerically. The proposed design of this adapter provides high power transmission what can be useful in some applications. Numerical modeling shows that developed adapter exhibits a voltage standing wave ratio less than 1,2 with an insertion loss of 0,1 dB in the frequency range from 4,5 GHz to 7,5 GHz.
