N2 - The phased array antenna system has been designed for electron Bernstein wave heating and current drive in the QUEST tokamak at 8.2 GHz. In order to control the launching polarization state, an orthomode transducer was designed to mix two orthogonal electric field components. The polarization state was arbitrarily controlled using phase difference and intensity ratio between the two field components. The fields radiated from the phased array antenna were evaluated using the Kirchhoff integral and HFSS codes. New designed phased array antenna steered a radiated beam to the desired launching-direction by the phased array.
