The properties of radiation from a parallel‐plate waveguide with an arbitrarily flanged surface of finite size are investigated by means of the boundary element method (BEM) based on guided‐mode extracted integral equations (GMEIEs). The reflection coefficient, the reflected and radiated powers, as well as the radiation pattern are numerically calculated for the incidence of a transverse magnetic guided‐mode wave. For a number of cases of flanged parallel‐plate waveguide, a variety of interesting phenomena have been presented numerically. These effects may be important in the design of antenna systems.
