目前,在美国和西欧,人们感兴趣的波段是毫米波波段(18千赫以上)。因为毫米波系统可提供高分辩率和精度,这两点在军用和民用雷达中,特别是在近距离内,都是非常必要的。另外在恶劣的环境中,如雨、雾、烟中,毫米波具有超群的工作本领。人们普遍的认为,未来的毫米波系统将会越来越依赖单片集成电路,而其所用天线也将采用毫米波半导体偶极子天线。尤其在通讯系统中,这种天线是既简单又适用的形式。 At present, in the United States and Western Europe, the band of interest is the millimeter wave band (above 18 kHz). Because millimeter-wave systems provide high resolution and precision, these are very important in military and civilian radars, especially at close range. In addition, in the harsh environment, such as rain, fog, smoke, millimeter wave with superior work skills. It is generally accepted that future millimeter-wave systems will increasingly rely on monolithic integrated circuits, and the antennas used will also employ millimeter-wave semiconductor dipole antennas. Especially in communication systems, this antenna is both simple and suitable form.
