Most antennas are made in the shape of a dish to collect and reflect the radio waves to the sub reflector, in the same way as a curved mirror focuses visible light to one point.───大多数天线被制成碟形，用以收集和反射无线电波至亚反射器，就像曲面镜将可见光聚焦于一点一样。
To catch these waves, radio telescopes usually have huge antennas.───为了捕捉这些电波，电波望远镜通常都有巨大的天线。
other part of the project is an undirected search which is monitoring all of space with a lower sensitivity, using the smaller antennas of NASA's Deep Space Network.───该项目的另一部分是无定向搜索，使用 NASA 深空网络的小型天线，以较低的灵敏度监测所有空间。
"Gripping any phone will result in some attenuation of its antenna performance, depending on the placement of the antennas, " he said.───“任何手机拿在手里，信号都会受到影响，取决于天线的位置，”他说。
'I didn't know I was actually going to be seeing the bugs, ' she said. 'The antennas. The shells. '───她说，我不知道我真的会看到这些昆虫，比如那些触角啊外壳啊。
All this is not to say that the next IMF managing director should be someone without political antennas.───这一切并不是说，下任IMF总裁应该由缺乏政治意识的某人担任。
Recently, uniplanar antennas have been used in many applications in millimeter-wave systems.───近年来，单面型天线在毫米波系统的应用相当的多。
Television stations said if the antennas burned broadcast signals would be affected but satellite and cable transmissions would not be.───电视台表示如果天线被烧毁的话广播信号会受影响，但是卫星和有线传输不会有影响。
Receiving antennas intercept part of this radiation, change it back to the form of electrical signals, and feed it to a receiver.───接收天线的装置接收部分电磁波，将其转换回电子信号，并供给一个接收器。
Radio antennas receive radio waves and change them into electrical signals which are then turned into sound by the speakers.
The wi-fi antennas pop up from the top and look like rabbit ears.
The antennas are controversial because researchers disagree over whether the electromagnetic fields from radio frequencies can cause leukemia and other illnesses.
Two novel spherical helical antennas are designed by projecting the planar equiangular spiral antenna onto the surfaces of hemisphere and partial sphere.
The gain of the single antennas are between 4.4 dBi and 7.1 dBi.
Using souped-up scanners and antennas, thieves station themselves near mobile phone callers.
The antennas are going up, wireless phones are in production, and the hype has begun.
The types of antennas used in these systems require a wide, unobstructed view of the horizon.
The coupling of linear antennas parallel to the minor axis in a elliptic waveguide are discussed by means of dyadic Greens function and reaction principle.
