Effect of non-ideal components on the performance of a reconfigurable on-board antenna for broadcasting applications

摘要

The extensive use of propagation impairment mitigation techniques for Telecommunication satellite systems working at Ka and Q/V bands represents an important countermeasure to prevent the broadcasted signals from strong degradation effects. In particular the use of an adaptive on board antenna for Broadcasting System Service, as reported in previous studies [1], appears as one of the most promising solutions. This contribution presents a new approach to simulate a reconfigurable antenna, the analysis of the effects of non ideal antenna components and the preliminary results obtained for this particular adaptive system.
