In the 21st lecture we calculated the properties of a magnetic dipole antenna. If we stack parallel two magnetic dipole antenni with a distance between them, and opposite currents, we have a magnetic quadrupole antenna. Find its radiation fields if , where R is the distance from a mid point on the -axis lying through the antenni to an observer, and is their radii. Find the far fields and the radiation pattern for the magnetic quadrupole antenna.
