Abstract
Lenses are one of the good approaches applying to the design of fan-beam antennas due to the ease of producing wide operating bandwidths, directive radiation beam, and high capability in linear and circular polarization to the antennas. Conventional dielectric lens antennas usually suffer from limited range of the effective refraction index and then bulky size. Therefore, meta-unit cell with high refractive index is developed to design the lens with compact size and excellent performance. In this paper, our recently developed meta-unit cell with high refractive index is summarized and presented. Its electrical performances under different excitation case are analyzed. Two designs base on the presented meta-unit including the end-fire fan-beam radiation antenna and the low-profile wideband metasurface antenna are presented. The compact structure and good performance make the meta-unit cell appropriate for designing lens with compact size.
