Description
Summary:Here, a new Faraday's cage using carbon nanotubes (CNTs) for radio frequency isolation is demonstrated. Densely packed CNTs were implemented on a guard ring structure. An antenna acts as a radiative source, while a receiving probe placed inside a CNT enclosure was used to measure the received signal. A total of 5-10 dB improvement in isolation was observed with the CNT enclosure, similar to what was obtained in an equivalent test structure with an aluminum enclosure. Such CNT isolation scheme could be implemented in densely packed three-dimensional circuits and packages, suitable for compact and light weight radar applications.
