Here we propose the different simple building block of the three-dimensional (3D) magnonic network in the form of the joined orthogonal sections of magnonic waveguides. It was shown, that the proposed 3D structures allows the  transmission of spin-wave signals in the regime of surface magnetostatic wave propagation without the significant losses due to the junction region. Micromagnetic simulation was used to reveal the mechanism of spin-wave propagation across 3D junction. An electrodynamic problem is considered by the finite element method and the dispersion characteristics of spin waves (SW) are constructed with a change in the geometric parameters of the  meander. The nature of the change in the frequency ranges of the Bragg band gaps depending on the meander profile has been studied in detail. It was demonstrated that spin-wave waveguiding 3D structure with broken  translational symmetry exploiting the vertical spin-wave transport provides the transmission of the information signal in three-dimensional configuration of magnonic networks.
