Agree transition between a rectangular waveguide and a rectangular waveguide with a T-rib

摘要

The invention relates to radio electronics and more particularly to matching transitions between waveguides and waveguides standard complex cross-section. The technical result consists in creating manufacturable available in production matching transition between a rectangular waveguide (PRV) and a rectangular waveguide T-rib (PVTR) with minimal reflection coefficients of microwave power in the entire range of operating frequencies of PRV. The apparatus consists of a portion with constant cross section PRB 1, PRV section with linearly changing section 2, T-edges 3, 4 and input 5 input 4 output transition section is located on an end portion PRV with constant section 1, which passes into a linear portion PRV varying section 2. On the end-face section is the last transition of output 5 for its articulation with PVTR. T-rib 3 is centrally positioned along the transition from the inlet 4 to the outlet 5. Dimensions of the T-ribs 3 increases with increasing longitudinal coordinate in the direction of PVTR. Full transition longitudinal dimension L is between λ to 1,5λ, where λ - the working wavelength. The longitudinal size of PRV portion with constant section 1 is in the range from 7/30 L to 13/30 L. 1 bp f ly-1-yl.
