    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: A lens antenna system is disclosed. The lens antenna system comprises a hybrid focal source antenna circuit configured to generate a source antenna beam for integration with different lens structures. In some embodiments, the hybrid focal source antenna circuit comprises a set of antenna elements coupled to one another. In some embodiments, the set of antenna elements comprises a first antenna element configured to be excited in a first spherical mode; and a second antenna element configured to be excited in a second, different, spherical mode. In some embodiments, the first spherical mode and the second spherical mode are co-polarized. In some embodiments, the lens antenna system further comprises a lens configured to shape the source antenna beam associated with the hybrid focal source antenna circuit, in order to provide an output antenna beam.

    Abstract: A positioning device and positioning method in which a first wireless signal is transmitted along a first signal path having a first signal path angle that changes relative to time; second wireless signal data representing a response of a wireless station to the first wireless signal is received; a third wireless signal is transmitted along a second signal path; and an assumption that an obstruction is between the wireless communication device and the wireless station is generated if the wireless communication device receives a response from the wireless station to the first wireless signal but does not receive a response from the wireless station to the third wireless signal; wherein the second signal path is a linear path.
