The radio frequency (RF) inductor includes a core being electrically non-conductive and ferrimagnetic, and having a toroidal shape, and a wire coil thereupon. At least one permanent magnet body is at a fixed position within the interior of the core, and an electrically conductive RF shielding layer is on the at least one permanent magnet body. The core may be ferrite for example. The electrically conductive RF shielding layer may be a conductive plating layer or a metal foil surrounding the permanent magnet body, for example. A magnetic field from the permanent magnet is applied to the inductor core to reduce losses, and the permanent magnet may be enclosed within the conductive shield to keep RF fields out. The inductor may be made small and have increased Q and resulting efficiency. The RF inductor may be applicable to RF communication circuits, for example, as an antenna coupler.
