The simulating models of existing waveguiding-slot antenna which is used in the transmitter of two-station radio-beam protection device called "Vitim" and its directional diagram, as well as the same waveguiding-slot antenna of alternative design which has asymmetrical directional diagram have been developed. Use of the asymmetrical directional diagram of the antennamitter enables creation of non-symmetric zone of detection, therefore it becomes possible to define direction of violator’s movement with the help of this two-station radio-beam protection device.
