中文摘要:
      二维通信系统(Two-dimensional Communication System, 2DCS)是一种以物体表面为通信介质的新型 通信技术,可以提供无线供电以及安全、高速的数据传输服务。为了改善二维通信中的供电性能,文中提出了一种 增强功率传输性能的二维通信导波板,该导波板包含三层:导电层、介质层和具有曲折网格的表面层。微波通过同 轴导波耦合器馈入二维通信导波板,可以在呈电感性的曲折网格表面任何一点耦合出表面层。经电磁仿真和实际 测试验证,与以前的二维通信导波板相比,曲折网格结构和阻抗匹配的同轴导波馈电器改善了二维通信导波板的传 输性能和电磁场分布的空间均匀性。
英文摘要:
      Two-dimensional communication system (2DCS)is a new communication system which uses the plate surface as the communication medium. 2DCS provides the wireless power to sensor devices and secure, high-speed data transmission services. In order to improve the transmission power in two-dimensional communication, a two-dimensional waveguide transmission board with enhanced power transmission performance is proposed in this paper. The board consists of three layers: conductive layer, dielectric layer and surface layer with meander mesh. Microwaves are fed into the waveguide plate by a coaxial waveguide coupler and can be coupled out of the surface layer at any point on the inductive zigzag reticular surface. The results of electromagnetic simulation and practical test show that compared with the traditional two-dimensional waveguide plate, the zigzag network structure and the impedance matching coaxial waveguide feeders improve the transmission performance and the spatial uniformity of the magnetic field distribution.
