摘要：
To further develop the advantages of loading artificial material units, layout rules of unit cells were investigated and presented for the first time in this study. Based on the analysis of transmission characters of metamaterial unit cells, some tapered slot antennas loaded with different unit layouts were designed. The result comparison showed that after the layout optimisation, the operation frequency band with a gain above 10dB increased by about 13% and the gain increased by 0.4-2.6dB in the high frequency band. In addition, the sidelobe level of H-plane also decreased by 0.7-4dB at different frequency points.
