Abstract:
Pattern reconfigurable antennas with multiple switchable beams can effectively improve multi-path effects and enhance channel quality. Therefore, they are considered one of the key technologies for intelligent wireless communication and IoT applications. Most conventional pattern reconfigurable works realize beam switching by introducing multiple reflectors or directors. However, this method usually suffers from large sizes, few beam states, and complex structures.
This talk will introduce a novel multi-mode manipulation method and several pattern reconfigurable designs. By superimposing an odd mode and an even mode, an aperture-shared even-odd mode system is built. The E-field distribution is manipulated by tuning the phase and amplitude states of the odd mode or/and the even mode. Thus, the main-lobe directions and beam shapes of the proposed multi-mode antenna are flexibly controlled. Then, multi-functional pattern reconfigurable antennas are developed, such as multi-beam switching and 360° continuous beam scanning. With the merits of compact sizes, novel working principles, and flexible beam-steering capacity, these proposed pattern reconfigurable antennas are good candidates for intelligent wireless applications.
