1. An apparatus comprising:
an enclosure; and
an antenna assembly comprising:
a switched beam mm-wave antenna array having radiating elements separated by less than half of an operational wavelength configured to be generated by the radiating elements, the switched beam mm-wave antenna array supported by a printed circuit board (PCB), the radiating elements fed by a transceiver chain that is configured to individually feed the radiating elements;
a low-profile mm-wave lens configured to direct a beam from the radiating elements and at least one of focus or defocus the beam, the low-profile mm-wave lens comprising a metal Fresnel Zone Plate (FZP) lens; and
a sub-10 GHz antenna configured to be fed by the PCB, the FZP lens comprising a center circle having a diameter larger than a length of the sub-10 GHz antenna.
