Abstract [en]

A two-dimensional Luneburg lens multiport antenna at 28GHz is presented, where an all metal metasurface structure is used to control the effective refractive index. The metasurface lens has glide-symmetric pin-loaded holes in the two plates of the parallel plate waveguide lens. This glide-symmetric configuration enhances the bandwidth of operation for the same equivalent refractive index. Excellent port matching and radiation performance are demonstrated through simulations of the complete antenna that is fed with 11 waveguides.
