TNO Defensie en Veiligheid Publication year 2007 Abstract This paper proposes a novel imaging architecture suited for use in the mm and the submm wave regimes. The structure is composed by a one dimensional array of radiators in order to enhance the image acquisition time with respect to single element detection. Moreover each of the antenna elements composing the array is characterized by a relatively broad band which opens the possibility for the array to be used over multiple frequencies or over a single wide band. Each of the radiators is a Leaky wave slot and all of them radiate in the presence of a unique dielectric lens. A prototype of the array has been designed to operate at relatively low frequencies (18-26 GHz). It has then been manufactured and measured. The performances are extremely promising and provide a hard proof of concept of the feasibility and the advantages of the proposed array architecture. © 2007 IEEE.
