    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.

    Abstract: In a recognition method, movement characteristics of an object are determined based on sensor information; image information of the object is determined based on the sensor information; and one or more gesture recognition operations are performed based on the movement characteristics and the image information to generate gesture recognition information. The recognition method may further include determining one or more physical characteristics of the object based on the image information; performing one or more physical characteristic pattern recognition operations based on the one or more physical characteristics to generate pattern recognition information; and generating a recognition output signal based on the gesture recognition information and the pattern recognition information.
