摘要： The invention relates to a diversity reception system for motor vehicles for digitally modulated terrestrial and/or satellite radio signals in the frequency range above 1 GHz. The system includes an antenna arrangement of which the reception signal is supplied to a radio receiver. The antenna arrangement is designed as an antenna system having several individual antennas and several antenna components, and contains a controllable logic switching device. The individual antennas and the several antenna components are positioned on the vehicle so that for discrete switching positions of the controllable logic switch, reception signals that are different in terms of diversity are available at the antenna connection point. A reception level testing device is provided for the comparative determination of the reception level contained in the data flow in the HF-channel with an HF channel bandwidth B. The level testing device is designed so that when initiated by the symbol cycle generated in the receiver and during the simultaneously occurring symbol identification of the received flow of data, the reception level is determined in each case within the shortest possible level testing duration.

摘要： A gimbal system is used for supporting and enabling the orientation of a circular satellite antenna dish in azimuth and elevation. The gimbal system includes a hoop structure, the ends of which are connected to the antenna dish. The dish is pivotally supported on the hoop structure for pivotal motion about its “X” axis. The hoop structure is mounted for rotation about the “Y” axis of the dish. The central axis of the hoop is coincidental with the central axis of the antenna. The hoop is driven by means of a motor to rotate the hoop and the antenna dish along therewith between a first position whereat the “Y” axis of the antenna is in its normal initial at rest (Y axis zero position) and a second position wherein the “Y” axis is rotated approximately eighty degrees from this initial position. A second motor is coupled to the antenna at one of the ends of the hoop structure to drive the dish about its “X” axis.

摘要： Transmit and/or receive antenna comprising an array (10) of radiating elements (12) and a controller for controlling the amplitude and/or the phase of the signals transmitted or received by each element so that the antenna is able to transmit or receive according to a specified pattern.

摘要： A miniature phased array antenna system employs a substrate having a high dielectric constant. A plurality of antenna elements are located on a surface of the substrate, and a superstrate having a high dielectric constant covers the antenna elements. The dielectric constant, thickness, and shape of the superstrate enable it to act as a dielectric lens for controlling the phase relationship of a signal received by the antenna elements. The design of the superstrate dielectric lens permits a reduction in the physical spacing between the antenna elements while maintaining spatial diversity in phase between signals arriving from different directions. Thus, the antenna array may be significantly smaller than conventional phased array antennas while maintaining a similar phase relationship to that achieved using conventional phased array antennas. Electronic circuitry coupled to each of the plurality of antenna elements applies complex weights to received signals prior to a summation thereof in order to reconstruct a desired signal and to deconstruct an undesired signal. SAW filters employed in the electronic circuitry are temperature controlled to maintain group-delay and phase-offset stability.

摘要： A cost effective electronically self optimizing antenna system is provided for use with each subscriber unit in both fixed and mobile wireless applications. The smart antenna consists of multiple antenna elements arranged so that individual beams independently cover sections of free space. Collectively, complete coverage of the desired free space is accomplished. The smart antenna uses a relatively narrow beam directed in the appropriate direction thereby reducing interference and improving system capacity. A controller is included which continuously monitors the signal quality and intelligently selects the optimum antenna beam pattern configuration. All telecommunication protocols, both analog and digital, can be accommodated by the controller.

摘要： An approach to antenna design optimizes gain, beam pattern, polarization response, and other qualities through self-replicating patterns based upon iterative transformations and candidate geometric shapes. In the preferred embodiment Hausdorff structures are used to realize &lgr;n-arbitrary different radiation patterns, including patterns optimized for multiple frequencies. The most preferred approach applies a sequence of different Hutchinson operators to different geometric subsets, thereby achieving patterns which are not only arbitrary in terms of wavelength/frequency, but also permit variable radiation patterns and variable polarization other desirable criteria. In addition to the use of variable scaling, geometric patterns, and the like, multiple structures may be placed within the same spatial footprint to permit reception over more bands. A dynamic reconfigurable antenna array is provided according to an alternative embodiment, enabling a single device to be simultaneously tuned to different or multiple frequencies or other response criteria. The antenna array may be made directional in its radiation (or reception) pattern either by changing the configuration of the array, changing the feed points in the array, or electrically steering the pattern using standard beam formatting techniques on multiple taps. Once a particular antenna architecture is defined, electrical or micro-mechanical switches are placed at key points of the structure enabling the pattern to be changed dynamically. Alternatively, a reconfigurable multi-dimensional array may be used having an active area optimized to maximize reception for a desired frequency and/or directionality.

摘要： An antenna utilizes multiple radiating elements placed at regular interval around a geometric structure. Each of the individual radiating elements are selectably activated in order to narrow the range of transmission and reception for the antenna. Larger antenna gain is achieved by narrowing the radiation pattern and each individual radiating element has significantly more gain than an omni-directional radiator while also reducing the power output requirements of the transmitter.

摘要： A system and method to individually characterize all of the antenna elements or amplifiers in an array antenna system simultaneously, without the need to perform sequential measurements. A positioning device allows movement of the antenna with respect to a calibration probe or movement of the calibration probe with respect to the antenna. Multiple simultaneous control circuit encoding (CCE) measurements of each of the array elements in an array antenna are performed. A second aspect of the system and method involves changes in the level of signals transmitted by the amplifiers in the elements of an array antenna system in conjunction with the use of orthogonal coding measurements. Changes in the level of signals transmitted permits simultaneous measurement of the amplifier characteristics of each of the array elements in an array antenna.
