无线电通信技术使用的日益增长需要越来越多的天线,以支持它们的数据传输。为这些天线找到足够的安放空间是很困难的事情。例如,海军舰艇通常使用金属天线来发射和接收甚高频信号。然而,这些凸出的天线装置导致视线出现问题,并且占用了船上大量的有用空间。此外,天线很高也会使舰艇被敌方雷达发现。通常海军舰艇需要80种不同类型的天线。随着天线需求的不断增加,较小型天线在节省宝贵的表面空间方面变得更有价值。
The increasing use of radiocommunication technologies requires an increasing number of antennas to support their data transmission. Finding enough space for these antennas is a difficult undertaking. For example, naval vessels typically use metallic antennas to transmit and receive VHF signals. However, these protruding antenna devices cause problems with the line of sight and take up a lot of useful space on board. In addition, the antenna is also high will make the enemy radar was found. Navy ships usually require 80 different types of antennas. As antenna needs continue to increase, smaller antennas become more valuable in saving valuable surface space.
