A novel type of broadband integrated array scanning in one plane is proposed. Such arrays are aimed to meet the requirements typically set for airborne synthetic aperture radars, while allowing the highest degree of integration between the T/R modules and radiating elements. The array is composed of broadband leaky-wave slot elements radiating by means of a wedge shaped dielectric lens. As a preliminary step this paper is focused on a finite number of infinite slots radiating in an infinite medium of the same permittivity of the lens. The problem is studied through a very efficient semi-analytical spectral domain procedure based on the assumption of small width of the slots in terms of a wavelength.
