SBD Synthesis of Dual-Band Perturbed Minkowski Monopole Fractal Antennas

Abstract

An innovative methodology for the design of dual-band microstrip monopole antennas is presented in this work. It leverages on the unconventional modeling of the radiator shape based on the perturbed Minkowski fractal in order to fit arbitrarily-defined resonances. A System-by-Design (SbD) technique is exploited to solve the arising global optimization problem with high computational efficiency. Representative benchmarks are reported to assess the effectiveness, reliability, and efficiency of the proposed synthesis approach.
