In this work, we explore the feasibility of designing active mantle cloaks for half-wavelength dipoles, aiming to massively reduce the antenna scattering cross-section while preserving its ability to radiate efficiently. A realistic cloaking device is proposed, consisting of split ring resonators loaded with active circuit elements, and its performance is rigorously validated through numerical simulations. In contrast to passive cloaks designed for antenna systems, the proposed device endows the antenna with stealth capabilities during reception without compromising its transmission performance.

Abstract
In this work, we explore the feasibility of designing active mantle cloaks for half-wavelength dipoles, aiming to massively reduce the antenna scattering cross-section while preserving its ability to radiate efficiently. A realistic cloaking device is proposed, consisting of split ring resonators loaded with active circuit elements, and its performance is rigorously validated through numerical simulations. In contrast to passive cloaks designed for antenna systems, the proposed device endows the antenna with stealth capabilities during reception without compromising its transmission performance.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
