A quadrature scheme is described for the calculation of the radiation field of an open-ended guiding structure directly from the longitudinal field components of the mode in the aperture. The calculated radiation pattern for a rectangular waveguide and a regular polygon dielectric rod agree well with known results. Radiation patterns for rectangular dielectric rod are also presented.

Inspec keywords: rectangular waveguides; dielectric waveguides; waveguide antennas; antenna radiation patterns

Other keywords: regular polygon dielectric rod; rectangular dielectric rod; rectangular waveguide; open ended guiding structure; radiation field; quadrature scheme

Subjects: Antenna theory; Waveguide and cavity theory; Single antennas
