The radiation properties from an open‐ended wedge‐type nonradiative dielectric waveguide are measured and compared to calculated values. The analysis is based on the assumption of a quadratic phase function for the field in the radiating aperture, as is used for the analysis of electromagnetic horns. It is found that the theoretical approach is valid. ©1999 John Wiley & Sons, Inc. Microwave Opt Technol Lett 21: 313–315, 1999.
