Microstrip Patch Antenna Design Using The Superformula

In this study, the super-shaped microstrip patch antenna is presented to demonstrate application of naturalistic geometry in antenna design. The shape of the antenna structure is modelled according to Superformula of Gielis, which helps to improve the antenna characteristics. The modelling of naturelike shaped patches provides the minimization of the antenna size and better return loss and gain. We have modelled a leaflike of a palm tree by a special choice of the parameters of the Superformula. The designed antenna attains -56.9 dB return loss at 5.02 GHz resonance frequency with operational bandwidth from 4.37 GHz to 6.1 GHz for -10dB. The dimensions of the antenna are minimized as 15mm×25mm.
