Mobile Phone Antenna System

摘要

A mobile phone antenna system includes a metal rear cover, a circuit board, a first antenna module and a second antenna module connected electrically with the circuit board. The metal rear cover includes a top cover, a middle cover with a distance from the top cover, and a connector used for connecting electrically the top cover and the middle cover. The circuit board is provided with several grounding points. The top cover takes the connector as dividing point. The first antenna module and the second antenna module are connected electrically with the top cover at one side of the connector. A number of second match circuits are connected electrically with the grounding points, and the mobile phone antenna system has better adjusting ability.
