Abstract
In this letter, a structure of a miniaturized ultra-wideband CPW-fed antenna and its design proce-dure are presented. The antenna is a modified version of the design previously proposed in the literature, with additional degrees of freedom introduced in order to improve the structure flexibility. The small size is achieved by executing a rigorous optimization procedure that consists of two stages: (i) smart random search carried out at the level of coarse-mesh EM simulation model that aims at finding an initial design featuring small size and reasonable return loss, and (ii) surrogate-assisted optimization exploiting variable-fidelity EM simulations and response correction techniques for expedited design tuning. The final design exhibits return loss below –13.2 dB in the entire UWB band and a small size of 418 mm2. Simulation results are supported by physical meas-urements of the fabricated antenna prototype.
