Reduction of cross polarization at higher frequencies is performed for a circularly polarized broadband antenna using a waveguide and an L-shaped feed probe. Cross polarization was enhanced at higher frequencies beyond cutoff frequency of first higher order mode in previously proposed structures by the authors. To reduce the cross polarization, the surface of short wall of the waveguide is modified to be curved. As a result, cross polarization is reduced by 5 dB to 10dB by the short wall with an ellipse-shaped surface. |
