A compact, light weight and highly integrated space fed 94 GHz antenna is proposed. Electronic beam steering is realized using a quasi-optical feed to a reconfigurable array. The antenna is a passive, low loss structure, which can be fabricated using conventional low frequency silicon semiconductor processing. The low loss also implies that it has relatively high power handling capabilities as only a small amount of power is dissipated within the antenna. The potentially low cost of production is an important factor for dual use applications. The proposal for Phase I outlines the effort to prove the antenna concept, predict the expected performance and resolve the fabrication issues. The development and experimental evaluation of a demonstration prototype is planned to be conducted in Phase II program. Such an antenna can have extensive application in Military as well as civilian applications. Millimeter-wave seekers, smart munitions and secure tactical communications are examples of this type of applications. Commercial applications include, collision avoidance automotive sensors, intrusion detection systems and personal communications to cite just a few examples.
