This article presents a proposal about an octagonal microstrip patch antenna (MPA) loaded with Split Ring Resonators (SRR) the antenna’s ground part. The antenna size reduction using multiband radiators will suits for miniaturization of day-to-day handheld devices. The dual band behaviour of the antenna will integrate more communication standard in one system which saves the installation space in the device. In this context, an octagonal antenna structure is conceived for a dual operational frequency of 5.63 GHz and 5.97 GHz. Hereby, a Co-planar Waveguide (CPW) structure is adapted to the octagonal patch and the structure has been observed by simulation analysis under HFSS platform. The overall geometry of the antenna is 30 x 26 x 1.6 mm3. The antenna feed using a microstrip for earning a better impedance matching between the antenna and transmission line. The antenna design provides a wider bandwidth of 580MHz and average gain of 3.25 dBm. The attainment of dual band operational frequencies is due to the CPW and SRR structure in the antenna design.
