Supershaped Sinuous Antenna for UWB Radar Applications

In this paper, we propose a novel class of sinuous antennas based on the integration of both 2D superformula and the sinuous one. The study was carried out with the aim to investigate the effects of some design parameters on the antenna performance in terms of radiation properties and impedance matching in a wide frequency range. In fact, thanks to the proposed formula, it is possible to generate a wide range of antenna shapes in a simple and analytical way by changing a reduced number of parameters. The analysis was carried out in the frequency range from 1 GHz to 10 GHz and the illustrated preliminary results highlight that the proposed approach could be an useful and flexible tool to create sinuous-like antennas having unique radiation properties.
