Abstract
The results of a radiation pattern measurement of a WR-28 open-ended waveguide (OEWG) are shown. At higher frequencies, the wavelength becomes shorter, making phase measurements very sensitive to positioning and alignment errors. The lack of symmetry in the measured phase reveals a misalignment of the OEWG. A two-parameter misalignment model is used to explain this asymmetry. The measurement data are used to determine the two parameters of the model, and the parameters are subsequently used to correct the phase of the measured radiation pattern, restoring the expected symmetry.
