Abstract

The findings of the design of frequency antennas for use in interlacing cognitive radio systems are discussed in this paper. Spectrum technology is being studied firstly to explain the results of the design of adjustable frequency antennas for use in cognitive interlaced radio systems. It is demonstrated that using reconfiguration alternatives in the two antennas of a Cognitive Radio (CR) system (both the observation and the communication one), and the adequate geometry of the radiator using convenient optimization techniques. The issue that needs to be addressed and the strategies outlined are described below. Subsequently, the designs, simulations and implementations carried out and the decision and usage requirements and considerations are illustrated in each case. Finally, there are some conclusions, which effectively validate the correct functioning of the proposed system.
