Abstract :
An experimental study of smooth finline to waveguide transitions is presented. It is shown that no optimum design exists and that very simple geometric curves can achieve better performance than some complex ones. A novel transformer-coupled coaxial-to-waveguide transition is also presented using a simple structure to achieve -20 dB of reflection across a 25% bandwidth
