摘要： The radiation characteristics of an antenna are made configurable including in the antenna a plurality of radiating elements and associating to each of said radiating elements a respective chain for processing the signal in transmission and/or reception with a module for weighting digital signals capable of applying to a digital signal at least a respective weighting coefficient and an antenna conversion set interposed between the module for weighting digital signals and one of the radiating elements of the antenna. The antenna conversion set operates on a digital signal on the side of the signal weighting module and on an analogue signal distributed on the processing chains associated to each radiating element of the antenna propagates (in transmission and/or reception), while respective weight coefficients are applied to said digital signal weighting modules. The weighting coefficients determine the radiation diagram of the antenna.

摘要： A subscriber identification card performing radio transceiver functionality for long-range applications incorporates a radio transceiver including an antenna formed on a card surface, an RF module and a base-band module. The antenna and the transceiver operate in the microwave/millimetre waves frequency range. This allows meeting the dimensional constraints imposed by the plug-in size and attaining a long-range operation. At least the base-band module might be integrated within the same chip executing standard security related functions for the terminal.

摘要： A method of performing digital beam forming on the radiation pattern of an array antenna using a plurality of antenna elements, each antenna element being coupled to a signal processing chain. A weighting phase is used in which at least a complex weight coefficient is applied to a digital signal in a corresponding signal processing chain. The digital signal is an intermediate frequency digital signal, and the weighting phase has the following steps: a) duplicating the digital signal into a first and a second digital signal; b) processing the first and second digital signals by multiplying the first and second digital signals respectively by a real and an imaginary part of the complex weight coefficient; applying a Hilbert transform to that signal which is multiplied by the imaginary part of the complex weight coefficient; and c) combining the processed first and second digital signals into a weighted digital intermediate frequency signal by subtracting the second signal from the first signal.
