Sažetak
Design of a fully metallic metasurface based implementation of planar Mikaelian lens is presented in this paper. The proposed lens has excellent potential in beam scanning applications and can be used as an alternative to exhaustively investigated Luneburg lens. In order to produce the necessary spatial variation of refractive index the lens is realized as a parallel plate waveguide loaded with quasi-periodic glide-symmetric holey metasurface. It is demonstrated that inserting coaxial pins into the cylindrical holes increases index of refraction, but also enhances isotropic properties, which is exploited in the design of the Mikaelian lens based multibeam antenna. The constructed lens antenna works in X-band, has 60◦ angular beam coverage and over the scanning range has side lobe levels below -10 dB and scan loss below 1.5 dB.
