Abstract

An optimized wide field-of-view (Fo V) ellipsoidal Dragonian antenna for near-field focused focal plane array (FPA)-fed Terahertz imagers is presented. We demonstrate the design equivalence between a paraboloidal main reflector and an ellipsoidal one. The proposed reflector configuration allows maximizing the number of active FPA elements and minimizing the array size during scanning. A joint analysis based on PO/PTD and MLFMM verifies that the optimum configuration can achieve a uniform scanning performance of a 40 mm HPBW on the near-field focal plane, a broad range of ± 16°FoV before reaching the 3dB scan loss limit.
