SOCRATE Project Focuses on Miniature Antennas with Super-Directivity

摘要

CEA-Leti and three partners in the SOCRATE project are developing innovative concepts to significantly improve the directivity of electrically small antennas. These antennas are generally limited to omnidirectional radiation, which is suitable for many wireless applications for communicating objects, such as UHF RFID, wireless telemetry and home automation. Nonetheless, the increase in small antennas' directivity could create new wireless applications with improved spectral efficiency, reduced environmental electromagnetic impact and usage features that increase functionality. The SOCRATE project is based on an analysis of the fundamental limits of radiation properties of compact antennas. It brings a new vision to the concepts of super-directional antennas with the contribution of new technologies.
