| Summary: | This article briefly presents the background of the study of cognitive radio systems (RC), as well as the use of reconfigurable antennas for this type of system, in particular the electrically frequency reconfigurable antennas and the most used reconfiguration methods highlighting their advantages and disadvantages. In addition, some hardware and software tools such as SDR (Software Defined Radio) and GNU Radio are presented and described, with increasing popularity in the field of research for evaluating the performance of these antennas, since they are low-cost and reconfigurables allow simple implementation of different communication schemes in which the system parameters can vary from the software. |
