Abstract: This is directed to an antenna for use in an electronic device. The antenna can be constructed from a flex and printed trace, such that the flex is originally defined to be as large or nearly as large as possible to fit within portion of the electronic device dedicated to the antenna. This can allow the antenna trace to vary as the antenna is tuned without requiring a new flex having a different shape. In addition, this can allow the antenna design to be decoupled from the mechanical considerations related to mounting the antenna within the electronic device.
