Abstract: | The cross-polarization level of circular and rectangular patches is evaluated by finding the peak value angles. The peak value is strongly dependent on substrate dielectric constant, varying roughly as1/epsilon. Aspect ratio of a rectangular patch has little effect on peak values or location. Patch thickness also has little effect; results are limited to thin patches as surface waves are not included. |
