Ground radiation

WebA "ground plane" antenna removes half the dipole and substitutes the ground plane for that. The inductance of the radiating element works with the capacitance between it and the ground plane to form the resonant circuit that gives the antenna proper tuning. When used this way, the ground plane may be called a "counterpoise". WebApr 9, 2024 · The linear synchronous motor ground stator operating frequency is 0–150 Hz; the rated current is 600 A, and the material is copper. Maxwell 3D uses tetrahedral mesh dissection, and the number of meshes depends on the size of the computational domain and the density of the mesh.
