Loop Antennas With Ferromagnetic Core TRIZ Cases
- Antenna Coils Under Display for Metal Case Eddy Currents
Filters block cellular signals to prevent eddy currents in metal casings, expanding near-field operation area.
- Antenna With Partially Saturated Ferromagnetic Substrate
Local magnetic saturation of a dispersive ferrite substrate reduces radiation losses while maintaining impedance stability for compact antennas.
- Orthogonal Coils on Ferrite Core for Hearing Instruments
A hearing instrument uses orthogonal coils wound on a shared ferrite core to enable compact wireless charging and data transmission.
- Motor Vehicle Door Handle Antenna Chamber Sealing
Composite connecting piece seals antenna chamber, protecting electronics from moisture and vibration.
