Abstract :
A printed pattern reconfigurable quasi-Yagi dipole antenna is proposed. The maximum beam of the antenna can be switched towards 20°, 0°, -20° with respect to the end-fire direction in E plane by changing the length of the microstrip-to-CPS (coplanar-strip) balun. For the three radiation states, the simulated overlapped impedance bandwidth is 11.5% with a centre frequency of 5.3 GHz and the simulated gain is 10.7 dBi. Compared to most of the reported beam-steering antennas, the proposed design has a much larger impedance bandwidth and a much higher gain. Future work on the antenna includes building a prototype with biasing network and conducting measurement of the antenna performance.
