The transmit coil assembly (100, 200) includes a first transmit coil set (10, 10') configured to resonate within a first frequency range and a second transmit coil set (12, 12') configured to resonate within a second frequency range which is outside the first frequency range and at least ten times higher or lower than the first frequency range. The transmit coil assembly (100, 200) also includes a ferrite element (202); and a housing (104) formed of a conductive material in which the first transmit coil set (10, 10'), the second transmit coil set (12, 12'), and the ferrite element (202) are disposed. The ferrite element (202) is disposed intermediate the first transmit coil set (10, 10') and the housing (104) and is configured to provide magnetic shielding substantially for the first transmit coil set (10, 10').",
