Hello!

I do not have much experience with MV AWR office if someone could help, I'll be grateful,
Coupling between coils in the near field UHF range,
I will post a photo below what I have done already in MWO EM Structure
I'll be grateful for all help I can get to simulate this.
How can I draw the loop in AWR mw Office as easy as possible or someone could send me an example of such a antenna.
How to draw the coil with AWR MW office, and simulated ?

I'm in the range of 800MHz to 1GHz


many thanks;)

Hello miky,

You can easily construct RFID Coils in AWR MWO using Microstrip component Spiral models usch as
Rectangular Microstrip Inductor without Bridge (EM Quasi-Static): MRINDNBR....

See the attached document for more details on how the coil is generated & can be simulated...
You can extract this to EM structure for accurate modelling....

Hello

somehow this does not work I have tried it is always some error ..

Hello miky,

Your EM extraction setup is wrong, first of all set up the dimension units to um instead of mm & try to use the MRINDNBR model and also make sure your schematic has MSUB, EXTRACT, STACKUP, blocks placed as shown in the attached picture & then do EM extraction & simulate for antenna analysis....

thank you many times

I hope that I am now wide

---------- Post added at 16:20 ---------- Previous post was at 15:24 ----------

The question now,,if I now Here are some of reel change, then stops working,I need something bigger coil working as antenna coil.
the chip supplied with energy.

so etwas will ich nach simulieren

hello manju

how can I coupling coils with Mw Office constitute,,I have so tries but it does not work the,,how do you do that I hope you have some time to help me

Hello Miky,

You can create two coils in one schematic & add the MGAP element with the coils spcing i.e. distance between the coils & properly arrange the layout & then finally extract as EM structure....

I have created two schematics one a single coil antenna for EM extraction & the other two coils for coupling analysis with 5mm spacing as an example...
see the attached modified MWO project & screen shots ...
