A compact planar 24GHz quasi-Yagi antenna for unmanned aerial vehicle radar applications

In this paper, a compact planar 24GHz quasi-Yagi antenna which uses a dipole driver is presented. The antenna is designed for unmanned aerial vehicle(UAV) radar which requires antenna's high integration and miniaturization. Quasi-Yagi antenna is a compact planar antenna suitable for millimeter-wave applications. In this work, a one-dimensional antenna array is used to meet the need for miniaturization. It not only dramatically reduces manufacturing cost but also eliminates the need for subsequent field failure control.
