Abstract: | In this paper, the far-field patterns are investigated for double-slot antenna array placed on extended hemispherical lenses.
The radiation patterns of the extended hemispherical lens fed by single double-slot antenna or double-slot antenna array are
computed using ray-tracing inside the dielectric lens and electric and magnetic field integration on the spherical dielectric
surface. The computation results show that the sharp null of the difference pattern is below -37dB. |
