Fault tolerance of reconfigurable pixel antenna using graph models

Abstract

This paper discusses the use of graph models for fault tolerance of reconfigurable antennas. Reconfigurable antennas can adapt to their environment and change their operation depending on the user’s request. Graph models are introduced for each configuration of the reconfigurable antenna to achieve the desired radiation performance. The use of graph models reduces the complexity while preserving its reliability allowing incorporations into applications like cognitive radio, MIMO, satellite communication and personal communication. A swifter response time is achieved with less cost and less losses. This method facilitates the development of the programming process for reconfigurable antennas. The graph theory facilitates the software control and also optimizes their performances. Graph modeling is also used to reduce the redundancy, complexity and increases the reliability of the reconfigurable antenna. The full analysis of these parameters allows a better implementation of the reconfigurable antenna in wireless and space communication. These models help the designers to analyze the antenna structures and transforms from bulky devices into mathematical and software models.
