Abstract :
In this paper, a high gain printed quasi-Yagi antenna is introduced for 60 GHz wireless applications. The antenna is fed by a novel microstrip-slotline transition consisting of a curved microstripline and circular slot in order to allow wideband characteristics. A corrugated ground plane is employed as a reflector for improving gain and small gain variation. The proposed antenna has an impedance bandwidth of 49.8-68.5 GHz for a -10 dB reflection coefficient and a gain of 10.50-12.8 dBi within this bandwidth. In addition, the antenna exhibits a stable radiation pattern with half power beamwidths of 36°-50° and 41°-52° in the E- and H-planes, respectively.
