A compact (20 × 20) mm2 swastika-shaped patch antenna with and without gap coupling for single band applications (X/Ku band) is proposed. Three designs are presented: the Design-1 is a simple swastika-shaped patch antenna without any gap coupling, whereas Design-2 and Design-3 are provided with vertical and horizontal gap coupling, respectively. The Design-1, Design-2, and Design-3 operate in the frequency range of (10.25–12.4) GHz, (11.74–13.52) GHz, and (10.74–13.63) GHz with resonating frequencies of 11.3 GHz, 12.6 GHz, and 12 GHz; peak gains of 3 dBi, 5 dBi, and 5.13 dBi; and maximum radiation efficiencies of 88.4%, 89.2%, and 87.2%, respectively.
