Based on the method of Dyadic Green s functions,the radiation patterns of the microstrip antennas printed on the surface of elliptic cylinder are analysised and calculated in this paper.

文中采用并矢格林函数方法，分析和计算了椭圆柱面上微带天线的辐射特性，并讨论了辐射特性随离心率的变化规律。

Feed positioning in the way that its phase center exactly coincides with the focus of the offset parabola and its direction so that the radiation maximum falls in the geometric center of the elliptic reflector surface are not intuitive at all, as in classic parabolic antennas.

馈源用这样的方式定位——其相位中心准确位于偏馈抛物线反射器的焦点，方向也要准确，这样辐射最大值才能落在椭圆形反射面的几何中心，这样一点也不直观，正如标准的抛物面天线。

It has also been alleged that the HAARP, or "High Altitude Active Auroral Research Project", which can use the ionosphere as a giant antenna for broadcasting signals, may be used to entrain various mind/body states in large areas of the planet.

也有人指称haarp ，或"高频率活跃极光研究计划"，可利用电离层作为一个广播信号巨型天线，可用于在地球的大范围诱导大脑/身体状态。

With a very simple antenna printable at high speed, this will be the cheapest EPC tag.

随着一个非常简单的天线打印高速，这将是最便宜的EPC标签。

This technique is presented to calculate the far field around the equiangular spiral antenna using the formula according to the former theoretical result.

通过给出该假设下射线场幅度和方向的分布，文中具体计算了平面等角螺旋天线在罩内的远区特性。

The new assembled digital Doppler rader was introduced in this paper. The results of comparison experiment show that the speed and direction of wind detected by the new rader conicide with those by tethersonde, and its functions are equivalent to those of Doppler acoustic radar with separated antenna developed previously in China and other countries.

本文对新设计的集合式数字多普勒声雷达作了介绍，对比试验结果说明新设计的声雷达测量风速和风向的结果与系留气艇测量结果相符很好，其性能与过去国内和国外分离式天线多普勒声雷达的性能相当。

In this context I am speaking of people who have limited space to erect an antenna.

在这上下文我是座位有限架设天线的讲话人。

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。
