Invited Speech Abstract:
With the rapid development of wireless communication technologies, the requirements for antennas with multi-functionalities are more necessary than ever before. Reconfigurable antennas, with the ability to change frequency, radiation or polarization characteristics, are promising in addressing new system requirements.They are able to alter their behaviors to adapt tothe changes in surrounding conditions.
In this talk, three types of reconfigurable antennas are presented. By controlling the radiation aperture with the aid of the p-i-n diodes, these designscan exhibit superior flexibility and controllability of frequency, radiation or polarization properties. In addition, the design ideas, results and advantages are also discussed.
