如何使用CR95HF参数计算电路部件？

，
 ，
非常感谢你的回复Pierre-Yves，
 我们是酒吧和餐厅的啤酒，苏打水和酒的控制系统制造商。我们有一个使用RFID技术的酒控项目。每瓶酒都会有RFID标签（在喷口内），我们将不得不用读卡器阅读。除了天线之外，整个阅读器将位于控制单元中，天线将是激活器（包括螺线管）的一部分，该激活器将连接到螺旋电缆。
 我们希望使用与应用笔记♯AN3394相同的电路。为了满足我们的测试需求，我们制作了一个阻抗为0.70μh的圆形天线，我们将其直接连接到读卡器电路。一切都很顺利。我们正处于使用激活剂进行测试的阶段。单独测量时，我们的天线的值介于3.83μh和4.01μh之间。当我们将它连接到螺旋电缆时，电线末端的测量值为6.31μh（天线为3.83μf）。
 螺旋电缆长6英寸，长60英寸。
 如果您需要更多信息，请告诉我们，
 非常感谢您的帮助。
 干杯。

Thank you very much for your reply Pierre-Yves,
We are manufacturer of control systems for beer, soda and liquor for bar and restaurant. We have a project for a liquor control that will use RFID technology. Each bottle of alcohol will have its RFID tag (inside a spout) that we will have to read with a reader. The entire reader will be in the control unit except the antenna which will be part of an activator (including a solenoid) which will be connected to a spiral cable.
We want to use the same circuit that is part of your application note ♯ AN3394. For the needs of our test, we made a circular antenna with an impedance of 0.70 µh that we connected directly to the reader circuit. Everything worked very well. We are at the stage of doing the tests with the activator. Our antenna will have a value between 3.83 µh and 4.01 µh when measured alone. When we connect it to the spiral cable the measured value at the end of the wire is 6.31µh (with an antenna of 3.83 µf).
The spiral cable will be a 6 conductors, 60 '' long when extended.
Let me know if you need more information’s,
Thank you very much for your help.
Cheers.

嗨罗杰，
谢谢你的澄清。
 
我的建议是，如果系统：天线+电缆+天线匹配高于4uH，天线匹配计算将不起作用。
因此，优选的是至少降低总阻抗，从而将天线单独的阻抗降低到1和2uH之间。
根据上面提供的参数，您应该具有与3/4 uH预期值匹配的总阻抗。
最后注意你的螺旋电缆，如果这根电缆短路或完全伸展，行为可能会有所不同。你是否已经进行了实验？
您忠诚的
PYB

Hi Roger,
Thank for the clarification.

What I can tell with your proposal is that the antenna matching calculation will not work if the system: antenna + cable +  antenna matching is higher than 4uH.
So it will be preferable to reduce at least the total impedance and thus reduce the antenna alone impedance between 1 and 2uH.
Based on the parameters provided above you should have a total impedance matching the 3/4 uH expected value.
Last take care about your spiral cable the behaviour can vary in case this cable is short or fully extended.Do you have already experiment it?
Sincerely yours
PYB

嗨Pierre-Yves，
 非常感谢你的回答。
 是的，我们已经尝试使用0.80μh的天线，总共3.33μh的电缆，它不起作用。你有什么我们可以尝试的吗？
 非常感谢您的帮助。
 干杯。

Hi Pierre-Yves,
Thank you very much for you answer.
Yes, we have tried an antenna of 0.80µh for a total of 3.33µh with the cable and it does not work. Do you have anything else we could try?
Thank you very much for your help.
Cheers.

罗杰你好，
 
如果您重新计算天线匹配电路，请告诉我，因为通过修改天线特性，您将不得不调整调谐电路。
这可以使用CR95HF EMI FILTER CALCULATION.xlsm电子表格完成。
告诉我它是否符合您的需求
 
感谢致敬

Hello Roger,

Can you please tell me if you have recompute the antenna matching circuitry because by modifiying the antenna characteristics you will have to adjust the tuning circuitry.
This can be done using the CR95HF EMI FILTER CALCULATION.xlsm spreadsheet.
Tell me if it is fitting your needs  

Thanks and regards
