Full Title
Full titles differ between systems:
IPC:
Loop antennas with a substantially uniform current distribution around the loop and having a directional radiation pattern in a plane perpendicular to the plane of the loop > with core of ferromagnetic material > Ferrite rod or like elongated core
CPC:
Loop antennas with a substantially uniform current distribution around the loop and having a directional radiation pattern in a plane perpendicular to the plane of the loop > with core of ferromagnetic material (H01Q7/02 takes precedence) > Ferrite rod or like elongated core
No child classifications to compare. This is a leaf node in both IPC and CPC.
