Signal source built-in type spherical dipole antenna

A signal source built-in type spherical dipole antenna is a globular dipole antenna device radiating electromagnetic wave, which is used in the cabinets, the screening effectiveness test of the frame, as well as other all classes of spherical dipole antennas of the electromagnetic compatibility test. The utility model is composed of a signal source part and the spherical dipole antenna part. The two top and bottom metallic hemisphere casings (1) are respectively fixed by two ends of the insulation support shaft (3), to make up of the spherical dipole. The centre section is fixed a group battery (4), a circuit board of signal source (7), an abutment sleeve (8), and a set nut (9). The side of the circuit board of signal source (7) is provided with two reed bases (10) provided respectively with two reeds (11). Two reeds (11) are respectively contacted with the two top and bottom metallic hemisphere casings (1) composed of the spherical dipole. The other side of the circuit board of signal source (7) is provided with a circuit controlling switch (5), and the handle of the circuit controlling switch (5) extends out the two top and bottom metallic hemisphere casings (1).
