Abstract
A wireless device may use two or more communication interfaces, in which operation of a first interface interferes with communication using a second interface. For example, a circuit board within a device housing may include an antenna used for communication with a first communication interface that is spaced apart from circuitry that includes a second communication interface. A conductor connected to the circuitry extends toward the antenna to transfer energy using induction. The conductor may engage a central portion of the circuitry associated with lower current than the edges of the circuitry to further reduce interference. The antenna is operated at a frequency that differs from the resonance frequency of the antenna, which may reduce the effect of interference to a larger extent than the associated loss in efficiency of the antenna. A matching network or other type of transformer is used to tune the output of the antenna.
