Abstract The paper briefly introduces a kind of spherical dipole antenna, which is
applied to EMC tests. Based on different feed points, the field patterns are simulated by
the use of FEM. The measured results are in agreement with the simulated results. The
method provides a guidance for the design of relevant antennas.
