Abstract: To realize the high reliable communication and the wireless power transmission in the wireless underground sensor network, a new type of 2D honeycomb magneto-inductivenetwork was put forward at VLF band. The system model was established, and bandwidth, group velocity and beam forming technologies were researched based on the current dispersion equations. Simulation with Runge-Kutta method was carried out to verify the efficiency of the network. The result show that the omnidirectional propagation can be realized in the proposed honeycomb network with more balanced bandwidth and group velocity in every direction compared with the square lattice structure. Directional communication can also be realized based on the cooperative multi-antenna technology. The proposed honeycomb magneto-inductive network is very suitable to build wireless sensor networks with high connectivity and power efficiency in the underground environments.
