With the increasing demand of the service for the communication equipment, reconfigurable antennas have become an important trend due to the performance diversity. However, the traditional reconfigurable antennas face new challenge in terms of the power -handling capability, wide tuning range, and portable applications. Based on the theory and design method of existing reconfigurable antenna, we combine the unique properties of liquid materials and reconfigurable antenna technology to develop new theories and methods for the reconfigurable antennas with application of liquid materials. We also research the method for achieving high-efficiency reconfigurable antennas, and then the design of some high-efficiency liquid reconfigurable antennas and liquid loaded reconfigurable antennas will be carried out. Based on the multi-mode resonator theory, the design method of wideband reconfigurable antennas is investigated; meanwhile, explore new feeding structures, and study the reconfigurable technology with wide tuning range for the liquid-based reconfigurable antenna. Combing with the frequency reconfigurable, polarization reconfigurable and pattern reconfigurable technology, the research of the multi-functional reconfigurable antennas will be studied. The research of this project is expected to address issues for the traditional reconfigurable antennas, and provide technical basis for the application of liquid materials in more wireless communications.
