dc.description.abstractRetro-directive backscattering is useful for improving link-budget in communication systems, localization and radar cross-section enhancement. Many existing technologies have limitations in terms of overall gain and scalability to higher frequencies. This thesis presents a new active retro-directive array architecture for Intelligent Transportation System applications such as automotive radar. The topology involves designing a phase-conjugating Rotman lens with reflection amplifiers for increased gain. Components of this architecture can be scaled to mm-wave. A reflection amplifier is prototyped and tested to have a maximum gain of 17.1 dB at 5.3 GHz. The circuit is then augmented onto a phase-conjugating Rotman lens. The amplifiers are tuned to ~ 6.5 dB gain at 5.15 GHz and the overall phase-conjugating performance is assessed. The active eleven element lens has a calculated backscattering gain of 19.2-25.4 dB across the scanning range of ±32 ˚ . Keywords: rotman lens, retro-directivity, phase-conjugation, ITSen_US
