A novel design methodology based on the Material-by-Design (MbD) paradigm is proposed. More precisely, the presented approach exploits a two-step quasi-conformal transformation optics (QCTO) algorithm in order to match linear arrays onto arbitrary surfaces. The synthesized meta-material lens, covering the conformal array, ensures that its radiation features are kept as much as possible equal to those of the reference antenna in free-space. Moreover, a source inversion (SI) strategy is adopted in order to achieve a reduction of the radiators in the final conformal arrangement. A study of the impact of the lens thickness on the achievable performance is presented, making use of full-wave simulations in order to carefully analyze the electromagnetic behavior of the synthesized radiating architectures. %D 2018 %K Material-by-Design (MbD), Array Synthesis, Conformal Arrays, Quasi-Conformal Transformation Optics (QCTO), Array Miniaturization, Source Inversion (SI) %L elediasc12772 %T Lens Thickness Impact on the Performance of Conformal Miniaturized Arrays Designed through a Material‐by‐Design Approach
