Received February 13, 2001

Analitical formulaes for the radiation pattern of a circular metal-dielectric waveguide (dielectric waveguide with a metal screen) open end are received in Kirchoff approximation. Numerical investigation of pattern characteristics which has shown the possibility of realisation of patterns (including patterns with circular symmetry) with low sidelobes level on both polarisations in wide frequency band is done.
