The Question of Line-Waveguide Junction With Conducting Exciter Element Optimization

The given paper is based on the line/waveguide junction synthesis algorithm. The recommended there calculation expressions satisfy the loss free and tuning conditions for junction unit. The corresponding calculation formulas are deduced by oriented signal-flow graph method., and to the synthesis of loss free threeport with tuning reactance are used. Thus at the given middle wavelength the reflection from the junction ports are absent. For synthesis of junction unit by the algorithm mentioned above are necessary: 1) line wave resistance, 2) input impedance value at the line output port.
