A broadband high-gain printed Quasi-Yagi antenna with a perturbation-based planar dielectric lens is presented. The perturbation design parameters are based on the diffraction gratings theory for gain enhancement, radiation pattern improvement, and higher order modes suppression. The proposed antenna provides 94.5% aperture efficiency with a high gain of 15 dBi at 30 GHz, high radiation efficiency of ~90%, and (24-40) GHz ultra-wide matching (S11 <; -10 dB) bandwidth. The measured cross-polarization is lower than -20 dB in both E - and H- planes. With these features in addition to being low-profile and lightweight, this antenna is suitable for various millimeter-wave applications.
