Device with a receiving antenna and a related power transfer system
First Claim
1. A device with a receiving antenna, wherein the receiving antenna comprises a secondary coil, and is arranged for inductively connecting to a transmitting antenna comprising a primary coil (202);
- wherein the receiving antenna further comprises;
a tertiary coil arranged to have a connection to a load in the device;
a capacitor to which the secondary coil is connected; and
an encapsulation comprising a low liquid permeability and non-conductive material encapsulating at least the secondary coil and the capacitor such that the tertiary coil is being wound around the encapsulation and the secondary coil; and
wherein the receiving antenna is arranged to resonate substantially at the same frequency as the transmitting antenna; and
wherein the entire receiving antenna is enclosed by a casing.
