Hello everyone, I am newbie at RFID sector. As a part of my project work, I wanted to design a RFID tag in CST. I tried
Anybody has any video or written instruction about uhf RFID tag design and port allocation process for CST simulation software? if you have then please send me the link or doc to this e-mail address: removed or share here. Thanks in advance.
how to design differential probe for tag antenna impedance measurement at uhf frequency(915MHz)
Hello everyoneWould you please tell me what should be the port impedance for simulation of RFID tag uhf passife antenna how to calculate
I want to read data from RFID tag. I use VS2010 C++ and Qt librabry to design a GUI. I can read data from passive tag but when I supply battery to this tag I cannot read any data. The RFID tag sensor I use is SL900A. In the SL900A datasheet, it has 2 logging forms and has different memory banks. I am a newbie so let me know (...)
Disclaimer - I am very very new to Electronics (literally a week), but am doing a lot of reading to try and catch up with the knowledge I need for my eventual project. Background: I run a lot of endurance running races and almost all of the races use uhf RFID passive chip timing systems where the runners wear a uhf passive RFID tag (...)
Hello, i want to design a uhf RFID tag antenna, before i arrive to this step, I wanted to replicate the simulation presented in the attached paper, i used the same parameters as mentionned in the paper, but i didn't get the same results, i'm getting a low adaptation level and a resonant in a different frequency, i can't identify where is the pro
Hi, I am trying to use CC1101 IC to read uhf RFID tags at ~868MHz. I have only seen EPC gen 2 Class 1 rfid tags for that range. Can I use CC1101 transceiver to read those tags? If not can I read any sort of RFID tags using this chip? Looking forward to your replies. Thanks a lot in advance.
Hi! I am going to develop RFID system which can read tag and update data to server. I am looking for reader which can read passive tag even if it is in pocket/bag or in box. What parameter/factor i have to see to find such type of antenna of uhf reader? I have read about linear and circular polarized antenna,but something i am (...)
I am working on uhf band of 866-868 MHz and will utilize CNT's as material for windshield RFID tag designation. Kindly help !!
Hi everyone, I am new to the field of uhf Passive RFID tag antanna's. I am using ADS tool to reproduce the tag antenna of a research paper. I have made the structure and set all the parameters like substrate material, conductor thickness, radiation box, solution frequency 866 MHz and the chip impedance 9.8-j73. I am getting very bad (...)
hi all, i really need help in finding chip for my antenna tag. i want to built an rfid at 8-12G but hardly to find chip that can matching with the freq. most chip areat uhf freq. do anyone can help on this?
At uhf you could use directional antennas. Also reader and tag antennas with linear polarisation and using the polarisation for the identification.
hi guys, i have used HFSS for a long time,and i also designed and fabricated two or three RFID tag antenna for various applications.but now,i confuse about some setup about simulation,beacause i had seen many different viewpoint to this,but i believe some of them must be wrong or fallacious,i hope u can help me and make clear why. my questons a
i am making my FYP "design and analysis of Low profile uhf RFID tag antenna for liquid bottles"on HFSS and i need to learn basic terms and system concepts involved in RFID, can anyone guide me which steps/note key concepts i have to follow during literature review?????
The RFID used for Road toll collection is usually a uhf chip operating on around 980 Mhz and will be a passive tag but capable of read and write at very high speeds even more than 100Kmph speed of the vehicle.
Hi, RFID passive tag is tuned to work at 865MHz (uhf band). What should be the frequency of oscillations for the clock generator used inside the tag?
I have done some research on this subject. but the thing is that, there are only a few iCs avialable for this reading kind of operations. I tried digi key, element -14, farnel, and everyone is saying no to me. My question is. >>Is there any dedicated IC for reading from a 865-867 MHz Passive tag?
i am new comer in uhf rfid. i am working development and doing a new project in uhf RFID. i want my passive uhf rfid tag can be read in some gallon of full water. example: there are nine gallons with tags. ninegallons are put such as square. how manner rfid tag which is located in center can (...)
First of all, we want to excuse us for my bad English.. I want to make project on "prevention anti collision system using RFID ". I'm facing many problem in select RF reader and tag . because ,I think according for this project required uhf generator ,tags ,reader all things are expansive. If any idea about "distance measure in RTL(real (...)
