E-PLANE RECTANGULAR WAVEGUIDES JUNCTION WITH VIBRATOR-SLOT COUPLING BETWEEN SHOULDERS

Abstract

Rectangular waveguide junctions are widely used in antennas and waveguide devices, therefore studying of their electrodynamic characteristics is important for practical application. Mathematical model of diffraction fields for E-plane T-junction of rectangular waveguides with a vibrator-slot coupling structure was built using the approximate analytical solution of the equations system for the currents by the generalized method of induced electro-magneto-motive forces. The model is characterized by the variable surface impedance on the monopole and constant surface impedance, distributed over the end wall of the semi-infinite waveguide. Multi-parameter studies of energy characteristics for the T-junction in the wavelength range of single-mode waveguides were carried out. The possibility of effective use of the impedance monopole as a control element for power dividing between the output shoulders of the junction in predetermined proportions has been shown.
