Abstract :
Based on the structure of left-handed transmission line (LH-TL), a novel phase shifter with higher power capacity is designed here. In the present structure, switches of phase shifters are mounted on fingers of LH-TLs, so the electric current through a single switch is only a fraction of that through the whole phase shifter. As a result, the power capacity of present phase shifter can be greatly improved. Changing the state of fingers of LH-TLs by controlling the switches, different phase shifts can be achieved. Besides its higher power capacity, present phase shifter possesses other advantages such as low cost, small size and easy fabrication. Finally, phase shifters of 11.25deg, 22.5deg and 45deg have been designed as examples.
