A structure and computationally efficient design optimisation procedure of a novel miniaturised UWB slot antenna has been proposed. Upon geometry parameter adjustment, the structure exhibits a very small footprint of just 161 mm 2 . This has been achieved by introducing sufficient number of degrees of freedom, including the parameterised multi‐section slot and a multi‐section load of the feed line as well as efficient numerical optimisation of all relevant geometry dimensions of the structure. The design process has been formulated as explicit size reduction problem. The electrical performance parameters (here, a maximum in‐band reflection) are controlled by suitably defined constraints. The final design has been verified through full‐wave electromagnetic simulation as well as physical measurements of the fabricated antenna prototype.
