Re: antenna measurement
HI GV....
i have the same problem about the antena measurement.
HOW to get accurate results and how to connect rfid antennas to VNA?
i have read about some paper on the rfid antenna measurement...
unfortunately,there is not any paper give some specific way to measure...
hi..
Is this chip antenna's impedance 50 ohm?
or is the antenna already embeded with rfid chip?...
I am not familiar with this kind of antennas..
could you give more commands about chip antenna?
regards..
ZY.
hi zirtapoz
as what you said,in real it is impossible to measure the antenna one by one..
but now my problem is a lab work.
I need a way to prove my simulation is right or not... i mean.. i dont know if the simulation is accurate without the comparation between measured result and simulated...
rfid micro measurement
hi zirtapoz
.i cant open the site.. my net is restricted i guess ....
would you pleased post it as postscript here.
however,i am still comfused about the RFID antenna impedance measurement.
as: 1.how to get VSWR?in UHF band,the common probe isnot accurate anymore...
cst backscattering
i have done read the CST rfid example.
in the material, it is said that Simulation of the planar structure with a standard 50 Ωport and then add matching network.
and in the practical application,the IC impedance is R+jx..so,the matching network is not fit here.
Now,my...
que es el back scaterring en rfid
As i said before try to download ansaoft designer(SW, free) and draw your antenna, put excitaion. and simulate. its easy.
but is it just simulation?
i want to measure the antenna after fabrication.. how to do this?.
Added after 7 minutes:
thanks GV.
.. i...
rfid reading distance measurement
hi all
I have the same problem in my study..
i donot know how to measurement the tag antenna's impedance (without the chip)
cause i want to know if my simulation is right.
is anyone know about this or have similar situation?
thanks,
ZY.
