A new geometry of the defected ground structure (DGS) is explored for rectangular patch for suppressed cross-polarized (XP) fields. This DGS looks like a combination of an ‘L’ and its mirror image and is termed as ‘L’-shaped DGS. This promises to suppress the XP radiations in the H-plane by more than 15 dB and over a wide angular range around its bore sight. Geometry wise it is the smallest of all if compared with its earlier versions. Basic insight into this phenomenon using substrate field distribution is also presented in the paper.read more

TL;DR: Shaped asymmetric DGS has been explored in this paper for probe fed circular microstrips for the first time right angle-bent ‘L’-shaped is one of them Another new DGS configuration conceived as "extended-arc" of asymmetric nature They are tested near 10 GHz The results presented in this paper indicate that the DGSs are effective for circular patch and do affect neither its resonance not the co-polarized radiations Among the two types, the extended-arc configuration is found to be more compact in nature Suppression in cross-p
