Where is the antenna located and how is it used on my Nokia phone?

Your device has an internal antenna, located inside the top of your phone and towards the back.Note: As with any other radio transmitting device, do not touch the antenna unnecessarily when the device is switched on. Contact with the antenna affects call quality and may cause the device to operate at a higher power level than otherwise needed. Avoiding contact with the antenna area when operating the device optimizes the antenna performance and the battery life.
