Abstract

With a glide-symmetric mushroom unit cell, a wideband Luneburg lens is integrated into print circuit boards (PCBs). Due to the low dispersion of such a unit cell of the metallic via in glide-symmetric technology, the equivalent refraction index of the unit cell remains stable versus a wide frequency range, which is a good candidate for the design of wideband Luneburg lenses. Electric fields in simulation has validated the proposed technology in a wide frequency band. Such Luneburg lens can be easily integrated with other microwave components in PCB technology, promising for applications as beamforming network and multibeam antennas.
