Abstract
The invention provides an electrical device, comprising a transformer () with a ferrite core () and an RF antenna (). The antenna () is electrically isolated from said transformer (), and a geometric dimension of the antenna () has a maximum dimension along or around a surface of the RF antenna (i.e. within the plane of the antenna or around a curved surface defining the antenna), and the RF antenna () is spatially spaced from a nearest part of the ferrite core () by less than the maximum dimension. This design makes use of the ferrite core of a transformer to provide isolation of the antenna from other parts of the device. This assists in reducing the impact of those parts of the device on the performance of the antenna, in particular the reception range.
