天线

The three antennas which receive VHF impulses emitted by a lightning discharge are placed on the vertices of a right-angled isosceles triangle with perpendicular sides 120 meters in length.

三个接收天线(接收闪电放电辐射的超高频脉冲)分别放在一个垂直边长为120米的直角等腰三角形的顶点，由到达天线的时间差来计算接收到的闪电脉冲的方向。

The antenna (100) is smaller than prior art omnidirectional antennas with the same bandwidth.

天线（100）的尺寸比具有相同带宽的现有技术全向天线小些。

Another term that is used for Wifi antennas are omnidirectional antennas.

另一个词是用于无线天线是全方位天线。

In the antenna system, a dual-reflector antenna with two paraboloids is fed by the beam waveguide feeding system formed by three reflectors, realizing quick scanning of the beam.

该天线利用由三面反射镜组成的波束波导对一个由两个抛物面镜组成的双反射面天线进行馈电，实现了波束的快速扫描。

The research on reconfigurable antennas is a hot point in the antenna field.

可重构天线是当前天线领域的研究热点。

In this illustrated embodiment, the dipole antenna structure is a folded dipole antenna 104 having a first and second bend.

在所例示的实施例中，偶极天线结构是具有第一和第二弯曲的折叠偶极天线104。

Replacing line cord antenna with a folded dipole antenna usually makes a big improvement.

替换电源软线天线用被折叠的偶极天线通常做大改进。

A new methodology for measuring the characteristic parameter of the circular polarization antenna using the linear polarization antenna is proposed.

提出了一种利用线极化源天线测量圆极化天线特性参数的新方法。

A broadband circular polarization antenna is then presented. Besides, we discuss how the different size of ground plane affect the antenna's performance.

其次，本文设计了一个宽频带的圆极化天线，并在此基础上讨论了不同大小的地板对圆极化天线性能的影响。

Furthermore, UHF antennas are smaller than VHF antennas; this is due to the shorter wavelengths.

此外，在超高频天线都小于甚高频天线，这是由于较短的波长。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
