We report on measurements and modeling of microwave propagation in graphene. In deep contrast with carbon nanotubes, which display very high impedances in the microwave range, planar waveguides patterned directly on graphene display a 50 impedance, which is tuned slightly by an applied dc. The high values of kinetic impedance in carbon nanotubes were not observed in graphene.
