چکیده
Since Huygens structures with phase shift lead to beam rotation, this manuscript discusses a phase shifter structure for the Huygens surface based on Tapered Slot Transition in the frequency range of 9.95-10.2 GHz using varactor diodes. By inducing an electric field along the tracks and placing diodes, the phase can be changed up to 200 degrees. With unit cells of 0.2λ -that this size is the smallest possible size for beam rotation structures - and a mega cell of 4 unit cells, incident angles of 0-15 degrees can be converted to transmitted angles of 10-45 degrees. The unit cell has been fabricated and it is shown that the measurement results are in good agreement with the simulation one.
