Design of high-directivity lens dipole antenna at 60 GHz

This paper presents the design and simulation of high gain dipole antenna with perforated dielectric lens working at millimeter-waves (55-65 GHz). The perforated dielectric lens by drilling numerous air-filled holes can be used to correct phase difference on the antenna aperture. By properly designing the radius of the holes, the dipole antenna with phase correcting lens achieves 10.2-15.6 dB gain variation. Compared with the dipole antenna without lens, the minimum gain enhancement is about 6 dB.
