EXPERIMENTAL PROOF FOR PATTERN RECONFIGURABILITY OF 60-GHz QUASI-YAGI ANTENNA

摘要

This article demonstrates the possibility of designing pattern reconfigurable quasi-Yagi antenna without compromising antenna's realized gain or operating frequency band. By controlling the length of dipole driven arms and the transition delay line, the E-plane beam direction of designed antennas are steered from -20 degrees to +20 degrees, in 10 degrees steps. In this communication, five separate 60 GHz antennas with different radiation directions are simulated, fabricated and measured. The experimental results match well the predicted ones and demonstrate that the radiation beam direction of quasi-Yagi antenna can be freely shifted. (c) 2015 Wiley Periodicals, Inc.
