Optimum antenna characteristic 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 antenna characteristic 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。
The antenna element has a ridge element unit (21) for adjusting antenna characteristic corresponding to a ridge portion and a radial element unit (22) for electromagnetic wave radiation.
