Wherein, the width of the gap 30 is 10-500 microns.
进一步地，如图1所示，在金属壳体10的适当位置设置两个馈电点20作为天线馈电。其中，一个馈电点20位于螺旋段31的内侧，而另一个馈电点20位于螺旋段31的外侧，以使金属壳体10激发最大的电感量。优选地，位于螺旋段31内侧的馈电点20邻近螺旋段31的内端点33，位于螺旋段31外侧的馈电点20邻近螺旋段31的外端点34，例如，位于螺旋段31内侧的馈电点20与螺旋段31的内端点33之间的距离小于或等于1厘米，位于螺旋段31外侧的馈电点20与螺旋段31的外端点34之间的距离小于或等于1厘米。Further, as shown in FIG. 1 , two feeding points 20 are set at appropriate positions of the metal casing 10 as antenna feeding. Wherein, one feed point 20 is located inside the helical section 31 , and the other feed point 20 is located outside the helical section 31 , so that the metal shell 10 excites the maximum inductance.
