Abstract:

On the last years, the globalization have raised the demand for communications services more efficient, mainly the mobile communication services. Final users of this services demand bigger facility and bigger commodity on the acquisition of information in little time and need to be in communication in every time and everywhere. It’s in this context that the Software Defined Radio (SDR) become extremely attractive. It refers to a multi-manner and multi-band device that accept different air interfaces and transmission band in the same equipment. To have the best performance of the SDR, for them respond in the same way to all possible configurations, the antenna would have be multi-band or wideband to receive a large range of frequencies without loss of power and unless quality production of reception. Thus, the smart antennas are fundamental piece in the SDR development. This article have the function to give a quick description of how the smart antennas theme have been treated by the SDR group of UnB and which proposal solutions looking at the solution of the problems and challenge that this subject involve.
