Abstract

When measuring at higher frequencies, as the wavelength becomes shorter, antenna phase measurements are very sensitive to positioning and alignment errors. The results of a radiation pattern measurement of a WR-28 rectangular open-ended waveguide (OEWG) are shown, and the lack of symmetry in the measured phase indicates 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.
