BCD01: Reconfigurable Antennas for Cognitive Radio

Friday, August 22  16:00-17:20,  Room #19

Session Chairs: Agostino Monorchio, Karu Esselle

Software radio, software defined radio (SDR) and cognitive radio (CR) system paradigms pose special challenges for antenna designers and researchers. Innovative designs are needed to achieve the broad band or multiband performance required by the adaptive nature of the transponders. Switched band antennas with integral solid state or MEMS switching devices are emerging as a possible solution, but significant challenges remain. Designers of integrated receivers may need to incorporate switchable filtering inside the antenna structure. Designers of broadband and multiband antennas for SDR in the mm-wave bands will face many fabrication and integration challenges. The session is intended to provide an update on the state-of-the-art in a class of promising techniques including miniaturization and software matching control, to derive novel and unconventional antennas operating over large bandwidths for SDR and CR.
