Abstract: This article aims to design a patch antenna (PA) that can resonate at three bands. Its architecture contains circular ring enclosed by a flower shaped aperture with circular notch at its center, best suitable for wireless communication applications. Central notch improves the reflection coefficient of designed patch antenna. Proposed design exhibiting three resonating band characteristics, first one is at 2.52 GHz with operating bandwidth (OBW) of 0.25GHz, second one is at 4.58 GHz with OBW of 0.57GHz and third one is at 7.2 GHz with OBW of 0.71GHz respectively. Proposed antenna is exhibiting a maximum peak gain of 3.8dBi at 2.52GHz operating frequency over FR4 substrate of thickness 1.6mm. The over all size of antenna is 41.8X28X1.6 mm3.
