Abstract
The use of non-linear electronic components is proposed in this contribution to further expand the potentialities of mantle cloaking for antennas. In particular, the possibility to design phased arrays featuring a radiation pattern that can be made self-sensitive to the level of received/transmitted power by the system will be demonstrated. Towards this end, a phased array exhibiting a directive pattern when operating for high-power signals while presenting an omnidirectional pattern for lowpower ones will be designed and numerically validated. This solution can be of particular interest for designing radar systems able to seamlessly/transparently switch between selectively scanning the environment when transmitting high power pulses, and omnidirectionally sensing the environment when handling low power scattered signals.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
