Cover Story: Through the years, inspiration from nature has taken the lead for technological development and improvement. This concept firmly applies to the design of the antennas, whose performances receive a relevant boost due to the implementation of bio-inspired geometries. In this scenario, the present paper proposes the analysis and optimization of bio-inspired spiral shell Dielectric Resonator Antennas resembling the Button snail Modulus modulus. The shape is implemented by means of Gielis’ superformula with the goal of boosting the antenna bandwidth and gain in the sub-6GHz range. The proposed configuration is also analyzed in terms of fabrication feasibility via Additive Manufacturing. View this paper
