"My Antenna is a 3-element Yagi, about 15 meters high from the ground."

使用三元件八木天线，离地15米高。

Each plane carried two directional Yagi antennas (looking something like a small TV antenna), one on each side.

每架飞机装备两个八木指向天线（有点象小型电视所用的天线），每边一个。

Then, the mutual between the driven and the parasitic element is analyzed in detail, and the even-odd-mode method is presented to explain the pattern characteristics of the two-element Yagi microstrip antenna.

最后，在寄生贴片上引入一种槽单元，通过改变槽单元的尺寸和位置，改变了八木天线的频率特性和方向图特性。

With the method of MOM,the gain matrix of antenna array is presented.

用矩量法推导并计算了三元八木天线阵的增益矩阵，进而分析在E面上增益与角度的关系，并给出了增益方向图的仿真结果。

I boughed my two 5-element 20-meter yagis from OH1JT and OH2HE.

我从OH1JT和OH2HE那里买了2副5单元20米波段的八木天线。

Methods: Five patients with parkinsonism or dystonia were assigned to general anesthesia using an modified endotracheal tube.

本实验依照人体实验之相关规定进行，五位患有帕金森氏症或肌张力异常的病人接受神经立体定位手术。
