In this paper, an electrical array antenna based on liquid crystal (LC) miniaturized phase shifter is designed and simulated, with the capability of beam steering from backfire to endfire. Special chamfered design of meander line is proposed to obtain compact phase shifter based on LC. The antenna integrates phase shifters, power dividers and patch antennas on a substrate to achieve reduced occupied...
A zero index metamaterial lens (ZIML) is proposed in this paper for antenna directivity and gain enhancement. The zero index metamaterial (ZIM) is constructed from both electric metamaterial with near-zero permittivity and magnetic metamaterial-modified split ring resonator (MSRR)-with near-zero permeability. The ZIM unit cell is numerically simulated in CST MWS. The scattering parameters show that...
