We report terahertz photoconductivity in epitaxial graphene devices patterned in a meander shape with the length up to a few centimeters and the width of few tens of microns. The photoresponse signal was measured at wavelengths of 280, 148 and 90 microns (frequencies 1, 2. and 3.3 THz) as a function of the electron concentration, bias current, terahertz radiation intensity and magnetic field. The photoconductivity mechanism based on the model of electron heating by terahertz radiation well explains the experimental results.
