Graphene-Based Transparent Fabry-Perot Antenna in D-Band

The limited bandwidth and availability of the electromagnetic spectrum below 100 GHz have led researchers to explore higher frequencies to provide high data transmission rates. This in turn requires innovative antenna technologies. This paper investigates the possibility of using multi-layer graphene to manufacture fully transparent antennas; i.e., antennas that can be integrated on a device screen. Experimental results in the D-band (110-170 GHz) show enhanced reflection behavior with respect to the glass support. This phenomenon is applied in constructing a transparent Fabry-Perot antenna. Simulated and measured results show good agreement, confirming the proposed design.
