摘要： The present invention relates to a method for beamforming a beam using an active antenna having predetermined aperture data comprising M x N dual polarized antenna subarrays within an aperture, each dual polarized antenna subarray comprising a first antenna subarray having a first polarization and a second antenna subarray having a second polarization non-parallel with the first polarization. The method comprises: selecting number of antenna ports, each antenna port being adapted to generate a separate beam using a combination from the first antenna subarray and/or the second antenna subarray; selecting port properties, comprising target beamwidth for each separate beam and desired polarization between beams; and determining port partitioning based upon aperture data and port properties for each antenna port, to adjust an effective length of the aperture over which the beam is created and thereby defining which first antenna subarray(s) and/or second antenna subarray(s) to use for each antenna port.

摘要： An N-element rotational-symmetric array antenna can generate N fixed pencil-beams simultaneously with an omnidirectional beam. An N x N Butler matrix can be used to feed the array antenna, using fewer than N input ports of the Butler matrix to produce the pencil-beams. One or more of the modes generated by the Butler matrix can be individually accessed to produce one or more corresponding omnidirectional beams. The N x N Butler matrix can be driven by a feed network that provides both power dividing and beam-steering, which permits simultaneous generation of the N pencil-beams.

摘要： A remote-controlled telephone system comprising a miniature telephone handset (300), a separate telephone transceiver (100) and a communication link (500) between the handset and the transceiver. The handset is constructed to provide conventional handset features such as an earphone (330) and mouthpiece (320). The transceiver is constructed with the bulkier power supply (110) and requisite antenna (130) necessary for communicating with a cellular array. Because the antenna is remotely disposed from the miniature handset, the antenna efficiency and the signal performance may be improved due to less interaction between the antenna and the user's body. Also the potential of interference to hearing aids will be considerably reduced. Moreover, the miniaturization of the handset will enhance the portability of the mobile phone and its ease of operation.
