Design of Square Waveguide Corner

The paper presents a full-wave design for matching a square mitered waveguide corner. We compare the full-wave numerical simulations with experimental results. The corner can operate with both polarizations, i.e. TE 10 for magnetic plane bend and TE 01 for electric plane bend. That is very useful for intended meteorological radar. That could use dual polarization transmit and receive both horizontal and vertical polarizations to assess additional properties of the weather targets.
