“…The basic idea of the new antenna relies on controlling the wave propagation characteristics of a thin dielectric slab waveguide (DSW) by introducing a perturbation in the DSW. Although this method has been used previously to improve the performance of different antenna systems and microwave components [21]- [24], however, the provided effective permittivity calculation was reported with via diameter dependency only, while there is another factor that should be accounted in designing this type of planar dielectric lenses, which is the spacing between air-vias. The provided effective permittivity calculation here includes the radius and the spacing between the air holes in two dimensions based on the diffraction gratings and the effective medium theories.…”

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.INDEX TERMS 5G antenna, high gain, lens, diffraction gratings, Quasi-Yagi.
