Electrodynamic characteristics of the crack which have been cut in a wide wall of a rectangular wave guide are investigated.
In resonant and non-resonant wave guide slot-hole aerials, one of the reasons of loss of capacity of a signal is a mismatch of entrance resistance of cracks with wave resistance of a wave guide. Possibility of reduction of influence of the specified lack by change of electrodynamic characteristics of a crack is offered.
By a technique outlined in [1] dependency diagrams of active ?onductivity crack radiations in a wave guide and from a wave guide, jet conductivity and factor of reflexion of a crack from its arrangement, the geometrical sizes and change of working length of a wave are constructed. The analysis of the received results from the point of view of possibility of maintenance of reduction of losses of capacity of a signal of a wave guide slot-hole radiator is carried out.
Possibility of maintenance of radiation of a crack in single-mode operation in the set range of frequencies with low factor of reflexion under condition of change of the geometrical sizes and crack position is shown. We specify recommendations about a purposeful choice of the sizes of a crack (width, length) and its positions in a wide wall of a wave guide. Reliability of settlement results is confirmed by their convergence on units of measure and check in boundary conditions.
