Abstract
This paper presents the design and evaluation of a high dielectric constant double-material integrated lens antenna for multi-beam or scanning applications. The lens is formed by two shaped embedded shells of different material permittivity to enhance both power transmission across the lens interfaces and the lens scanning characteristics over a broad frequency range, when the feeds are integrated at the lens base. Design is based on Geometrical Optics formulation and the lens performance is evaluated using the classic hybrid Geometrical Optics / Physical Optics approach (GO/PO). The proposed lens concept is experimentally validated with a fabricated MACOR/Acrylic prototype, showing less than 1 dB scan loss up to ±20º with Gaussissity better than 95% over 40% frequency band at millimeter-waves
