A built antenna and the electronic device

The present invention provides an internal antenna, the antenna comprising: a dielectric substrate, the radiating element attached to a grounding unit surface of the dielectric substrate, opposite to the radiating element the feed point and the ground point; radiating element is bent metal detour band, the present invention also provides an electronic apparatus applying the internal antenna. Internal antenna according to the present invention, i.e., by a simple structural design to meet the performance requirements of the antenna can be flexibly applied to an electronic device, used in conjunction with low-loss dielectric substrate of the antenna, so that the effect of the antenna built in an electronic device and existing external antenna is substantially the same effect, to meet the requirements of existing electronic device receives radio signals, while the lower cost, suitable for mass production.
