摘要： A method for weight training for beamforming in handset terminals deployed in a system employing Frequency Division Duplexing and Time-Division Multiple Access (FDD/TDMA). Generally there is signal in time slots that are not destined for a certain terminal. During this time the receiver scans a beam around the terminal and measures received signal strength, determining the best beam angle and storing corresponding weights for transmission.

摘要： A hierarchical phase shift and delay apparatus enables a large broadband phased-array antenna that is not subject to beam squint. The size of the phased-array antenna both in physical dimension and in number of array elements determines the number of hierarchical delay levels. A method for squint compensation distributes control signal values for phase shift, gain, and time delay for each block. Embodiments of digital squint compensation include phase shift indexers, a plurality of switches coupled to ground taps of a floating strip to adjust the characteristic impedance of a transmission line for fine adjustment; and a hierarchy of tunable squint compensation structures including die-level squint compensation structures coupled to each of the radio frequency chains; and panel-level true time-delay phase shift structures coupled to each of the die-level squint compensation structures. The article of manufacture enables aggregation of sub-arrays which are fabricated to avoid beam squint.

摘要： A process writes phase shift error correction values into a phased-array antenna to normalize a range of manufacturing variances. An axial ratio is determined for an antenna weight vector (AWV) by making multiple measurements with the horn of a test antenna mechanically rotating from 0 to 180 degree or with dual polarization test antenna. For calibration of the whole array, each subarray is treated in the same fashion as equivalent to an antenna element in the subarray calibration. The subarray is electronically rotated as a whole (all elements rotated by the same phase shift value) from 0 to 360 degree during the full array calibration. Due to small power variation among AWVs, calibration solely by REV results fail to consistently converge to resolution. Accordingly, the apparatus measures and compares axial ratios. During final fabrication, the apparatus programs an AWV with best axial ratio into each non-transitory array element.

摘要： An apparatus consisting of hierarchically elaborated antenna modules is calibrated by steps. Although the AWV can be calculated mathematically based on the required phase shift values of each antenna element for a beam direction to compensate for signal delay. However, in practice, due to hardware implementation imperfection, coupling in signal path for each antenna element within hardware, inaccuracies of implementations, physical misalignment, the mathematically generated AWV does not necessarily provide alignment between transmit beam and receive beam. This subset is sufficient is all practical operation. The subset of AWVs are typically called codebook and the receiver beam points to different direction by using a AWV within the codebook.

摘要： The present invention provides a method and system for operating a wireless communication system in which received signals from a plurality of antennas are weighted and combined with a beam forming operation to form an output signal. In an embodiment of the present invention, beamforming operations are performed with maximal ratio combining (MRC) and an interference nulling algorithm (INA). The INA receives an error signal which is 180° out of phase with a combination of the channels for individual antennas, referred to as the SUM channel. The error signal is determined by complex conjugate multiplication of the individual signals and a reference complex signal. The weight amplitude is controlled by weight normalization to provide faster convergence and prevent integrator overflow.

摘要： A low profile, vehicle mounted, in-motion tracking, satellite antenna includes a pair of antenna assemblies mounted in parallel on a rotatable platform. Each antenna assembly includes two subreflectors with a plastic matching element. The outputs of the two antenna assemblies are coupled with a single phase shifter. The combined outputs are retransmitted to a receiver inside the vehicle. The satellite antenna also includes a receiver for receiving channel selection data and/or for providing two-way communication with equipment inside the vehicle. The antennae, transmitter and receiver are self-powered by a storage device which is charged by a wind driven generator. A retractable radome lowers to a lower profile when the antenna is not in use.
