Multiband 3D universal antenna

A multiband 3D universal antenna system comprising:

• a magnetic core surrounded by a multiaxial coil wound around each of three orthogonal axis X, Y, Z, said multiaxial coil including at least two different coils wound around at least one of said three orthogonal axis, each coil of each axis having a specific cross section and a given number of turns and each coil being provided with two external connectors;
• a support configured to provide backing and/or isolation of said coils;
• and
• a connection box connected to said external connectors, said connection box configured to provide a reconfigurable interconnection between said external connectors, said reconfigurable interconnection configured to provide a given inductance range, quality factor (Q) range, and sensitivity range to operate within at least three different working frequencies,
• wherein the coils include six coils (12X1, 12X2, 12Y1, 12Y2, 12Z1 and 12Z2), which are arranged around axis X, Y and Z, three of said six coils (12X1, 12X2, 12Y1, 12Y2, 12Z1 and 12Z2) are configured to operate under a 125 kHz or 134.2 kHz frequency and three of said six coils (12X1, 12X2, 12Y1, 12Y2, 12Z1 and 12Z2) are configured to operate under a 20 kHz frequency.
