Design of reconfigurable antennas using graph models (Q2847540)

The book is devoted to the design of antennas that adapt to their environment and tune their operation as quickly as possible. The software control of antennas requires their modeling in a mathematical form. The book investigates the possibility of using graph models, which are symbolic representations of relationships between different points in a system. Graph models transform reconfigurable antennas from their bulky mechanical states into software accessible devices that can be optimized, trained, corrected, and searched for efficient communication purposes. Particularly, in Chapters 3 and 4 it is shown that the modeling of reconfigurable antennas using graphs leads to a redundancy reduction approach that eliminates unnecessary components from the antenna structure. The correlation between the reliability and the complexity is detailed in Chapter 5. In Chapter 6, the formulations done on single element reconfigurable antennas are expanded for dealing with reconfigurable antenna arrays. Finally, detecting and overcoming switch failures in reconfigurable antenna arrays are discussed in Chapter 7.
