A reflective phase shifter is proposed to realize the two-dimensional beam-scanning reflectarray.The reflectarray is composed of double-dipole resonant elements in which the phase shift is implemented by ap-plying a driving voltage to the liquid crystal(LC).A 30×30 phase shifter sample is fabricated on a quartz sub-strate with a 480 μm thickness and a 4 cm × 4 cm area.According to the experimental results,0 to 360° phase shift can be achieved within the bandwidth of 5 GHz.In order to accomplish two-dimensional beam-scanning and reduce the negative impact of driving lines on the reflec-tarray,a new LC driving method is developed.To verify the accuracy of the proposed approach,three samples of different driving line numbers are designed using the above-mentioned phase shifter,which all have achieved a 0-360° phase shift in the bandwidth of 4 GHz.Consider-ing the influence of LC anisotropy and inhomogeneity,an improved calculation result is obtained and compared with experimental data.
