A kind of metallic perturbation on the ground plane of a microstrip patch has been examined indicating some interesting as well as useful features. A strategic geometry, its location, and dimension can magically improve the pattern symmetry and also the cross-polarized (XP) level. A pair of metallic posts in an X-band rectangular patch demonstrates the same indicating about 20 dB improvement in the XP radiations. This design is free from fabrication tolerance and other high frequency related issues. © 2020 IEEE.
