In a tomographic imaging system, the key is to collect a sufficient number of scattered field points to recover the currents in the inverse scattering problem. This can be accomplished by using a real array of multiplexed antennas for real time imaging. In this paper, a W-Band Retina for Terahertz tomographic imaging is presented. A system based on a retina, a collector and an illuminator is described and the results of a fabricated retina are shown.

A set of antenna geometries for future integrated arrays at terahertz frequencies, based on two fabrication techniques is presented. The first technique consists in an advanced laser micro-fabrication, allowing fabricating advanced 3D geometries but may not be cost-efficient for large arrays. The second one is based in photolithographic processes, allowing the fabrication of arrays on a single wafer in parallel.
