Title

Active Rotman Lens for Low-Cost Passive Millimeter-Wave Imaging Systems

Abstract

Mm-wave imaging systems have been conventionally used for high end applications implementing sophisticated and expensive technologies. Recent advancements in the silicon integrated and low loss material passive technologies have created a great opportunity to study the feasibility of low cost mm-wave imaging systems. However, there are several challenges to be addressed first. Examples are modeling of active and passive devices and their low performance, highly attenuated channel and poor signal to noise ratio in the mm-wave.

The main objective of this thesis is to investigate and develop new technologies enabling low-cost implementation of the mm-wave and submm-wave imaging systems. To achieve this goal, an integrated active Rotman lens architecture is proposed as an ultimate solution which combines the unique properties of a Rotman lens with the superiority of the CMOS technology for fabrication of low cost systems.
