    摘要： An adaptive antenna reception apparatus includes a reference signal level determination section, reception level detection sections, and beam formers. The reference signal level determination section determines the level of a reference signal for generating an error signal used for antenna adaptive control on the basis of a reception level of each antenna before beam forming. The reception level detection sections calculate antenna weighting factors for the respective paths on the basis of the multiplex signals received through the respective antennas and the error signal output from the reference signal level determination section. The beam formers receive the received multiplex signals and form antenna directivity beams for the respective paths in accordance with the antenna weighting factors output from the reception level detection sections.

    摘要： An electronically steerable phased array antenna module having a conformable circuit element. The conformable circuit element forms a packaging architecture which includes a flexible substrate on which the control electronics of the antenna can be mounted directly or electrically coupled to the flexible substrate. The radiating elements are integrally formed on the substrate together with monolithic transmission lines which couple the radiating elements to the integrated circuits forming the control electronics. In one preferred embodiment, integrated power combiner/splitters may be integrally formed on the conformable circuit element and integrated transmission feed lines are formed on the circuit element coupling the power combiner/splitter circuits to the control electronics. The conformable circuit element provides a packaging architecture which enables a large plurality of antenna radiating elements and associated interconnecting transmission and feed to be packaged in a cost efficient and compact manner, and which can be easily adapted for a variety of different forms of phased array antennas.
