COUPLING FEED-IN MOBILE PHONE ANTENNA DEVICE

摘要

Disclosed is a coupling feed-in mobile phone antenna device. The antenna device comprises a main board disposed in a mobile phone, a "loop" metal decorating part mounted on the front of the mobile phone, an antenna carrier mounted on a housing of the mobile phone, and a first antenna radiator and a second antenna radiator that are disposed on the antenna carrier. The second antenna radiator is provided with a gap. A radio frequency feed source is disposed on the main board, and the radio frequency feed source is connected to the second antenna radiator through an antenna connector. The main board is connected to the first antenna radiator and the metal decorating part through the antenna connector. The metal decorating part is in communication with the second antenna radiator through the antenna connector. The present invention skillfully adopts the metal decorating part on the front of the mobile phone as a part of the antenna, and greatly enhances the metal texture of the whole machine with respect to the shape, and meanwhile, the present invention adopts a coupling feed-in manner to well solve the problem that an antenna is sensitive because the performance of the antenna deteriorates severely when a gap of a metal frame is grasped by the hand.
