Abstract
In this paper, a broadband metamaterial electromagnetic unit is proposed, and its left-handed characteristics are designed and verified. On this basis, a metamaterial leaky-wave antenna based on a double-layer substrate integrated waveguide is proposed. The antenna is composed of 13 double-layer metamaterial elements. The simulation results show that the antenna can be used in the 6-10.3GHz frequency band. The angle between the axial direction of the antenna and the normal direction of the antenna can be changed from -70° to +76°, the half-power beam width of the antenna is 12°, and the antenna's 3-dB gain bandwidth reaches 52%. In addition, in the operating frequency band, the cross polarization is always at least 45dB lower than the primary polarization, which is more advantageous than the performance of the same type of metamaterial leaky-wave antennas reported in the literatures.
