AbstractOver the past two decades, research on 2D materials has received much interest. Graphene is the most promising candidate regarding high‐frequency applications thus far due to is high carrier mobility. Here, the research about the employment of graphene in micro‐ and millimeter‐wave circuits is reviewed. The review starts with the different methodologies to grow and transfer graphene, before discussing the way graphene‐based field‐effect‐transistors (GFETs) and diodes are built. A review on different approaches for realizing these devices is provided before discussing the employment of both GFETs and graphene diodes in different micro‐ and millimeter‐wave circuits, showing the possibilities but also the limitations of this 2D material for high‐frequency applications.
