Abstract :
The cross polarized (XP) radiation from a probe-fed circular patch, its variation with the change in probe location from the matched to slightly offset configuration, and the application of a pair of dot-DGS to suppress that the XP levels are investigated. Some significant results are provided based on a series of simulation and experimental studies.
