Abstract:
This paper presents a wideband compact quasi-Yagi antenna for C, X and Ku-Band applications. The proposed antenna structure has a simple feeding mechanism consists of a microstrip line and a transmission line. Half of the driver and director are printed on the opposite side of the substrate to ensure good coupling between the antenna elements and achieve a stable radiation pattern. In addition, the ground plane is also modified with U-shaped slots allowing better impedance matching and enhanced bandwidth performance. The proposed antenna can achieve −10 dB bandwidth of 90% between 5.2 - 13.7 GHz and a gain of 3.6 - 6.5 dBi across the bandwidth with a compact size of 0.85\lambda_{c}\times 0.69\lambda_{c} at the center frequency. The antenna is a good candidate for wireless communication systems, phased arrays, and mm-wave imaging systems.
