Wideband Self-Complementary Quasi-Yagi Antenna for Millimeter-Wave Systems

Novel wideband quasi-Yagi antennas, each featuring a self-complementary structure together with a triangular notch on the ground plane, are proposed. The optimized proposed antenna offers an improved relative bandwidth of 74%, gain of 4-8 dBi, and stable endfire radiation patterns within the passband. Good agreement between simulation and measurement is shown.
