The aim of this contribution is to describe an innovative wire antenna able to automatically hide or reveal its presence depending on the waveform of the received/transmitted signal. This unconventional behavior is achieved through the use of a cloaking metasurface (MTS) made of a meander-like unit cell loaded with a lumped-element circuit. Due to the engineered time-domain response of the lumped circuit, the antenna is able switching its behavior when interacts with either a pulsed signal (PW) or a continuous signal (CW). The proposed configuration paves the way to a new generation of self-adaptive cloaking devices for antenna applications.

Abstract
The aim of this contribution is to describe an innovative wire antenna able to automatically hide or reveal its presence depending on the waveform of the received/transmitted signal. This unconventional behavior is achieved through the use of a cloaking metasurface (MTS) made of a meander-like unit cell loaded with a lumped-element circuit. Due to the engineered time-domain response of the lumped circuit, the antenna is able switching its behavior when interacts with either a pulsed signal (PW) or a continuous signal (CW). The proposed configuration paves the way to a new generation of self-adaptive cloaking devices for antenna applications.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
