We investigate the thermal phase shift in an integrated terahertz silicon effective medium waveguide at a frequency of 0.15 THz. The obtained value of the thermo-optic coefficient opens the possibility of creating thermally tunable phase shifters for future THz phased antenna arrays, which will become the basic elements of new generation communication systems with a high data transfer rate.
