New Challenges for Antennas
Antennas are gaining ever increasing importance for they dramatically influence system performance as new challenges are popping-up for wireless systems in terms of mobility, terminal compactness, bandwidth, multiservice, or resilience to harsh impairments from the scenarios, to name just a few. Also new services are hitting mass market along with its own challenges for the technology. Work on antennas at IT is following some of these challenging trails: new wideband antenna configurations for enhanced MIMO array performance, new antenna developments for item localization up to centimeter scale using UWB-IR, tag antennas for next generation RFID based on hybrid UHF/UWB approach, shaped dielectric lenses for gigabit LANs at mm-waves. On-going work will be presented by students and researchers from IT.
