ABSTRACT:
A built-in antenna configuration uses a metal frame or metal shell of an electronic communication product as the ground end of the antenna. The ground end connects fixedly a signal end to form a built-in antenna configuration, in which the ground end is substantially parallel to the signal end. The built-in antenna configuration without a ground end can effectively reduce the internal occupation space of an electronic communication product relative to a conventional antenna with a ground end. The built-in antenna configuration can indeed make an electronic communication product reach the requirement of a miniature, meet the appeals of easily stowing and conveniently carrying, reduce the manufacturing cost thereof and thus promote the product competition and the added value thereof.
