In this contribution, we discuss the potential of electromagnetic invisibility for antenna arrays. We focus our attention on a popular and widely-used parasitic array, i.e., the Yagi-Vda antenna, and we will show how electromagnetic cloaking enables tailoring its radiation pattern in several unprecedented manners. In particular, we first show how cloaking allows interlacing more Yagi-Vda arrays making possible the design of extremely compact and directive dual-band antennas with opposite pointing directions. Then, we describe the case of a power-dependent Yagi-Vda antenna whose radiation pattern can be tailored by acting on the antenna input power.

Abstract
In this contribution, we discuss the potential of electromagnetic invisibility for antenna arrays. We focus our attention on a popular and widely-used parasitic array, i.e., the Yagi-Vda antenna, and we will show how electromagnetic cloaking enables tailoring its radiation pattern in several unprecedented manners. In particular, we first show how cloaking allows interlacing more Yagi-Vda arrays making possible the design of extremely compact and directive dual-band antennas with opposite pointing directions. Then, we describe the case of a power-dependent Yagi-Vda antenna whose radiation pattern can be tailored by acting on the antenna input power.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
