Researchers demonstrate a graphene-based tunable microwave antenna

A European collaboration of scientists from Romania, Greece, Italy, and Ireland demonstrated a graphene antenna that operates in the microwave part of the spectrum and can be tuned by applying a voltage. Graphenea supplied the graphene for this research.  

The antenna is less than 1mm thick and has a planar diameter of 100mm, which according to the team makes it one of the smallest microwave antennas in the existence. It was produced using a simple fabrication procedure and a standard CVD graphene layer on an SoI substrate.
