Advanced reconfigurable RF/microwave electronics

摘要

The radio spectrum facilitates a wide variety of applications and services but has become overly crowded, especially in the past two decades. Spectrum resources are in ever-greater demand as new applications emerge and existing ones continue to grow. Reconfigurable radios can mitigate the problems associated with limited spectrum availability and limited open bandwidth by tuning to the frequency and standard that is least heavily used at any given time. In this paper, reconfigurable electronic technologies based on microelectromechanical systems (MEMS) as well as phase change materials are discussed with applications in reconfigurable radios.
