In this contribution, we report our recent experimental results on a fully passive antennas-based carpet device inspired by Van Atta array configuration for retroreflectors. We have realized an electrically large triangular bump over a ground plane, whose sides are covered by two arrays of conventional patch antennas. The antennas are connected to each other following a VanAtta-inspired connection, which ensures the restoration of the reflection angle as if the bump were not present, mimicking the ground reflection. The performances have been experimentally evaluated, showing the ability of the proposed setup to mimic the reflection from a ground plane for different illumination angles.

Abstract
In this contribution, we report our recent experimental results on a fully passive antennas-based carpet device inspired by Van Atta array configuration for retroreflectors. We have realized an electrically large triangular bump over a ground plane, whose sides are covered by two arrays of conventional patch antennas. The antennas are connected to each other following a VanAtta-inspired connection, which ensures the restoration of the reflection angle as if the bump were not present, mimicking the ground reflection. The performances have been experimentally evaluated, showing the ability of the proposed setup to mimic the reflection from a ground plane for different illumination angles.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
