摘要：

In this paper, the theoretical far-field patterns and Gaussian-beam coupling efficiencies are investigated for a double-slot antenna placed off axis on extended hemispherical silicon and quartz lenses. Measured off-aids radiation patterns at 250 GHz agree well with the theory, Results are presented that show important parameters versus off-aids displacement: scan angle, directivity, Gaussicity, and reflection loss, Directivity contour plots are also presented and show that near-diffraction limited performance can be achieved at off-axis positions at nonelliptical extension lengths, Some design rules are discussed for imaging arrays on dielectric lens antennas.
