20120263056 | APPARATUS, METHODS, AND ARTICLES OF MANUFACTURE FOR WIRELESS COMMUNICATIONS - Selected embodiments are directed to methods, apparatus, and articles of manufacture for wireless radio frequency communications. Adjacent antenna array elements of a receiver antenna array are separated by less than the diffraction limit of the radio frequency communication band in which the apparatus and methods operate. A plurality or multiplicity of near-field scatterers are asymmetrically placed in the immediate vicinity of each of the antenna array elements, to perturb the pattern of each of the antenna elements, making the patterns different even below diffraction limit spacing. A transmitter spatially and temporally focuses simultaneous transmissions on each of the antenna array elements, using time reversal communication techniques. The transmitter may transmit through multiple antenna elements, and the channel from the transmitter to the receiver may be subject to multipath phenomena. | 10-18-2012 |
