摘要： A shared beamformer flexibly allocates beams among clusters of beams produced by phased array antenna apertures that are deployed on a satellite (or other type of platform). By sharing the beamformer among the beam clusters, if one beam cluster is not providing useful coverage, the beams may be reallocated to one or more other beam clusters that are providing useful coverage. To share the beamformer among the beam clusters, a selector network is used to select which particular beam cluster (or clusters) is used for producing one or more narrow beams that are constrained to the coverage area of the beam cluster (or clusters).

摘要： The enclosure of the receiver device is divided into an antenna vicinity enclosure 1 and a demodulation unit enclosure 2, which are connected by a single transmission cable. By disposing the antenna vicinity enclosure 1 in the vicinity of the antenna, the high frequency feeder cable drawn from the antenna to the antenna vicinity enclosure 1 can be shortened. The effect of pulse noise and high frequency noise picked up by the conventional feeder cable can therefore be reduced. Furthermore, the length of the feeder cables in a quantity corresponding to the number of antennas is then reduced and the wiring space for the feeder cable can be reduced. The demodulation unit enclosure 2 is disposed spaced apart from the antenna, and the wiring space for the transmission cable can be greatly reduced in comparison with a case where a plurality of feeder cables are wired in the wiring space.

摘要： An apparatus that is employed to increase the data transfer capacity between transmitters and receivers for short-range data communication, particularly for the ISM frequency bands where different transmitters with different modulation and transmission methods operate in the same frequency band. The object is achieved by orienting antenna lobes that provide high antenna amplification towards transmitters and receivers in the local area of the apparatus, with the result that the distance loss between a transmitter and receiver becomes less than the distance loss represented by the lobes oriented away from the apparatus and the inbuilt amplification in the apparatus. In contrast to a normal 'repeater' function for increasing a coverage area, the object is particularly achieved of increasing the capacity in an area where there is already a good transmission channel between transmitters and receivers. The various transmitters and receivers are divided into sub-networks that are isolated from one another, and where the connection is broken between transmitters and receivers that do not communicate with one another. By doing this on the physical level, one is independent of a chosen modulation method and transmission protocol. Thus the invention is especially suitable within the ISM frequency band where a countless number of known and unknown modulation methods and protocols may exist.

摘要： Antenna system (30, 50), that includes a plurality of antenna arrangements (32-35, 51-54, 550) each having one or more ports, and all ports connected through transmission lines in a combining/splitting circuit (552). The antenna arrangements form a spatial phased array able to track a satellite (36, 62) in an elevation plane by mechanically rotating the antenna arrangements about transverse axes (302, 305, 56) giving rise to generation of respective elevation angles (el-e3, 31, 41, 42) and changing the respective distances (D, D1, D2, 37, 38) between the axes in a predefined relationship with the respective elevation angles. The combining/splitting circuit provides phasing and signal delay in order to maintain pre configured radiating parameters. The arrangements can be mounted on a rotating platform (55, 558) to provide azimuth tracking. The system provides dynamic tracking of satellite signals and can be used for satellite communications on moving vehicles.

摘要： A wireless communication receiver ( 20 ) comprises an antenna structure ( 22 ) and a joint searcher and channel estimator ( 24 ). The antenna structure acquires dimensionally differentiated signals which are concurrently utilized by the joint searcher and channel estimator for determining both a time of arrival and channel coefficient. The wireless communication receiver can be either a mobile terminal or a network node (e.g., a radio access network node such as a base station node, also called Node-B). In "spatial" embodiments, the antenna structure comprises an array of plural antennas. The signals acquired by different antennas of the array are dimensionally differentiated with regard to a spatial dimension, and the time of arrival and a composite channel coefficient are essentially concurrently determined by the joint searcher and channel estimator. In "temporal" embodiments, the antenna structure comprises an antenna which provides signals for each of successive sets of pilot data received by the antenna as the dimensionally differentiated signals.

摘要： A phased array antenna system with controllable electrical tilt generates two signals V2a and V2b with variable relative delay therebetween. The signals are converted into antenna element drive signals by a power distribution network (100). The network (100) splits each of the two signals V2a and V2b into three signal components. Pairs of components of different signals are input to respective (180) hybrid coupling devices (hybrids) (110, 112 and 114), which provide vector sums and differences of their inputs and act as phase-to-power converters. Their outputs are distributed between further (180) hybrids (116, 118 and 120), which act as power-to-phase converters and provide antenna element drive signals with phase varying both with element array position and also with the variable relative delay between the two signals V2a and V2b. Antenna electrical tilt is therefore controllable by altering a single relative delay.

摘要： A reception circuit includes a reception section and control section. The reception section performs frequency conversion of an input signal by using a local frequency signal generated by phase comparing operation. The control section removes a passing phase error, added in the reception section, on the basis of a phase comparison signal output from the reception section. An adaptive array antenna system is also disclosed.
