摘要： A frequency management scheme for a hybrid communications/positioning device, such as a cellular/GPS or other combined device, generates a local clock signal for the communications portion of the device, using a crystal oscillator or other part. The oscillator output may be delivered to a phase locked loop to drive a high-frequency clock for the cellular or other communications portion of the hybrid device. A processor may determine frequency error between the phase locked loop and base station or other reference, to derive a digital frequency tracking message. A Doppler search or other logical control message may likewise be communicated from the processor to a GPS or other positioning receiver. The GPS receiver circuitry may consequently adjust Doppler center, window width or other parameters to enhance time to first fix or other performance. The architecture eliminates the need for a second crystal or other direct oscillator in the GPS receiver portion of the hybrid device, while still maintaining GPS performance. The architecture of the design also eliminates the need for frequency correcting elements in the crystal oscillator or other base reference oscillator or clock. The invention can furthermore be used in any system, radio, modem, transceiver, or receiver that has two or more receivers that share one reference or base oscillator or clock.

摘要： Based on a received signal y(t) received by a radiating element of an array antenna including the single radiating element and a plurality of parasitic elements, an adaptive controller calculates and sets a reactance value of a variable reactance element for directing a main beam of the array antenna in a direction of a desired wave and directing nulls in directions of interference waves so that a value of an objective function expressed by only the received signal y(t) becomes either one of the maximum and the minimum by using an iterative numerical solution of a nonlinear programming method.

摘要： This invention provides a phased array antenna comprising an input, a feed network electronically coupled to the input, a plurality of radiating elements, a plurality of continuously voltage tunable phase shifters for receiving signals from the feed network and providing phase shifts for the signals prior to transmitting the signals to the radiating elements, and a controller for controlling the phase shift provided by the phase shifters. The phased array antennas can be configured to produce beams that can be scanned in one dimension (one-dimensional) or two dimensions (two-dimensional) by using continuously adjustable phase shifters that are based on low cost, low loss voltage-tunable dielectric materials.

摘要： An array of dielectric resonator antenna elements (1), each element (1) being composed of a dielectric resonator disposed on a grounded substrate (3), a plurality of feeds (2) for transferring energy into and from the dielectric resonator elements (1), wherein the feeds (2) of each element (1) are activatable either individually or in combination so as to produce at least one incrementally or continuously steerable beam which may be steered through a predetermined angle. Both the element beam patterns generated by the individual elements (1) and the array factor generated by the array as a whole may be independently steered. When these are steered in synchronism, it is possible to improve the overall gain of the array in any particular direction.

摘要： An advanced external beam steering controller (AEBSC) for use with a phased array antenna which requires only spherical coordinate pointing information to be supplied from a remote controller. The AEBSC uses the spherical coordinate pointing information, as well as stored information for the X, Y and Z axes locations of each specific antenna element of the phased array antenna, to generate actual phase shift values needed to be applied to each antenna element in order to point the antenna in accordance with a predetermined pointing angle. The invention significantly reduces the amount of electrical cabling required for communicating with the external controller, and also reduces the required data rate at which information must be supplied from the remote controller to the AEBSC.
