我的申请需要使用一个灵活的薄PCB。
我想使用天线设计的形式CyPress天线参考指南(HTTP://www. CyPress)/DooptOnt/Appult- NoSe/AN91445-AutoNET-Read and Rf Lay-Out-Tu准则,但在本文件中,它们仅指厚度为0508mm(20MIs)的PCB板。柔性PCB厚度仅为0.1mm(4MIs)。如何调整传输线的宽度? 是否有可能将天线和接地平面放在一层PCB上的同一层上(这对原型来说更容易)? 以上来自于百度翻译 以下为原文 My application requires to use a flexible thin pcb. I would like to use the antenna design form the cypress antenna reference guide (http://www.cypress.com/documenta ... f-layout-guidelines ), but in this document they only refers to pcb boards with thickness of 0,508mm (20mils). The flex pcb is only 0.1mm (4mils) thick. How I have to adjust the width of with of the transmission line? And is it possible to have the antenna and ground plane at the same layer on a one layer pcb (would be a lot easer for prototyping)? |

我不知道你需要调整天线的宽度来补偿深度的减少,但是你也可以做一些无线传输天线的计算来确定,或者一些尝试和错误?
你可以将接地平面放在与天线相同的层上,但是接地平面的目的是提供单极天线的后壁。将接地层移动到同一层,防止将其放置为单极排列,并防止天线后接地平面壁的降噪效益。然而,它确实允许一个更全方位的天线。 最后,我认为你需要测试你的布局来找到最佳的选择,或者在更高的数学层次上进行一些无线设计分析,以确定情感的结果。 以上来自于百度翻译 以下为原文 I don't know how much you need to adjust the antenna width to compensate for the decrease in depth, but you can either do some wireless transmissions antenna calculations to determine that, or some trial and error? You could have the ground plane on the same layer as the antenna, but the purpose of the ground plane is to provide the back wall of a monopole antenna. Moving the ground layer to the same layer prevents you placing it for a monopole arrangement, and prevents the noise reduction benefits of the ground plane wall behind the antenna. It does allow for a more omnidirectional antenna however. Ultimately, I think you would need to test the layout you go with to find the best option, or to do some wireless design analysis at a more mathematical level to determine the affective results. |
