Abstract: 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.
