摘要

PURPOSE: An antenna device is provided to improve the performance of an antenna by using a dual metal frame composed of an inner metal frame and an outer metal frame. CONSTITUTION: A main antenna radiating body(220) is placed at a mainboard(210). The main antenna radiating body is electrically connected with a feeding end(203) of the mainboard. A dual metal frame is positioned along a circumference of the mainboard. The dual metal frame comprises an inner metal frame(230) and an outer metal frame(240). The inner metal frame is electrically connected with the feeding end of the mainboard or the main antenna radiating body.
