摘要： One or more input signals are used to generate a Pseudo noise generator and re-inject the signal to obtain a more efficient method of control of a receiver using adaptive antenna array technology. The antenna array automatically adjusts its direction to the optimum using information obtained from the input signal by the receiving antenna elements. The input signals may be stored in memory for retrieval, comparison and then used to optimize reception. The difference between the outputs of the memorized signals and the reference signal is used as an error signal.

摘要： A multi-band antenna system for MIMO applications is adapted to provide high isolation between antennas across a wide range of frequencies. Multiple Isolated Magnetic Dipole (IMD) antennas are co-located and connected with a feed network that can include switches that adjust phase length for transmission lines connecting the antennas. Filtering is integrated into the feed network to improve rejection of unwanted frequencies. Filtering can also be implemented on the antenna structure. Either one or multi-port antennas can be used.

摘要： A multi-frequency antenna comprising an IMD element, one or more active tuning elements and one or more parasitic elements. The IMD element is used in combination with the active tuning and parasitic elements for enabling a variable frequency at which the antenna operates, wherein, when excited, the parasitic elements may couple with the IMD element to change an operating characteristic of the IMD element.

摘要： The spiral sheet antenna allows a small efficient antenna structure that is much smaller than the electromagnetic wavelength. It achieves the small size by introducing a high effective dielectric constant through geometry rather than through a special high dielectric constant material. It typically includes a rectangular cylinder-like shape, with a seam. The edges of the seam can overlap to make a high capacitance, or they can make a high capacitance by simply having the edges of the seam very close to each other. The high capacitance serves the same role as a high dielectric constant material in a conventional compact antenna.

摘要： A cellular communication system is described where beam steering techniques are applied to fixed and mobile communication devices to increase system capacity, with capacity optimized for downlink or uplink performance. A previously described technique wherein the current mode on a single radiator is altered to vary the radiation pattern of the radiator is utilized in an FDD cellular system to generate multiple radiation patterns with low correlation between the patterns. Techniques to restrict or expand the frequency bandwidth of the beam steering technique are described to provide the capability to beam steer at receive frequencies or transmit frequencies only, and techniques are described where beam steering can occur at both transmit and receive frequency bands from a single active antenna system. The capacity per cell in the cellular system can be improved for either downlink or uplink by commanding the fixed or mobile devices to optimize correlation between radiation modes for the downlink or uplink frequencies.

摘要： The instant disclosure concerns an antenna system and method for location-finding of a wireless communication device. A cellular multimode antenna is configured to analyze pilot signals from base station towers across a plurality of antenna modes. Information corresponding to the received signals and each antenna mode is analyzed to determine a location fix. In certain optional embodiments, the location fix determined by the cellular multimode antenna is used to determine an optimal mode for a second GPS modal antenna, such that the selected mode of the GPS modal antenna provides optimum signal quality with the global positioning system. In this regard, the cellular multimode antenna estimates the location of the device, and a mode for the GPS modal antenna is selected based on the location fix such that the GPS antenna is capable of quickly determining a precise position of the device.

摘要： An impedance tuning and optimization technique is described wherein an impedance interface is dynamically tuned prior to applying transmit power to the circuit. A coupled signal injected into the antenna port is used to optimize the tuning state of a tuning component such that the impedance properties of the circuit are optimized prior to application of transmit power. A coupled or injected signal at an alternate frequency band can be utilized to determine tuning state or parameters at the frequency of interest by first tuning at the frequency of the coupled or injected signal and then accessing a data base containing information that relates tuning parameters across multiple frequency bands for various levels of antenna de-tuning. A time-savings is realized when the tuning circuit is optimized prior to activation or use of the transmit/receive path.
