Passive reflectors for wireless communication networks and methods of their fabrication are disclosed. In one embodiment, a passive reflector for reflecting a RF beam, the passive reflector includes a dielectric substrate. The passive reflector also includes a reflector includes an array of unit cells, where the reflector array is provided on a surface of the dielectric substrate, each unit cell includes a first conductive loop and a second conductive loop that is orthogonal to the first conductive loop, and each unit cell provides a phased distribution for two different polarizations.
