Optimum antennacharacteristic can be obtained by adjusting the position and the numerical value of the matching unit.
通过对匹配单元的位置和数值进行调节，可以获得最佳的天线特性。

Further, an optimal antennacharacteristic can be obtained since the antenna is spaced apart from a printed circuit board by a predetermined distance.
此外，由于天线被离开印刷电路板一预定距离，因此能获得最优的天线特性。
