Abstract
An antenna module and communication device containing the antenna module are disclosed. The antenna module is disposed in a metal cavity. The antenna module includes a switched beam mm-wave antenna array having radiating elements separated by less than a wavelength of the radiating elements. The array is fed by a single transceiver chain. The array is disposed at the focal length of a low-profile mm-wave lens configured to steer the beam. A sub-10 GHz antenna is disposed closer to the opening of the cavity than the lens. The lens is a Fresnel Zone Plate lens having a focal length of less than about the wavelength of the beam, or a Saucer lens having shells of different refractive indexes and having a profile that is more than 6 times smaller than a Luneburg lens with a same focal length.
