Background
Description
Results and DiscussionRFID uses electromagnetic fields to automatically identify and track tags attached to objects. mm-wave RFID labels take this technology further to show the ability of on-body sensing with higher data being recieved.
This type of technology is useful for specific and / or critical environments.Applications such as body sensing for runners, various sports, identity and key information for workers and medical use.
Objectives:
- Create 2 antennas, one being
868MHz and the other 24GHz.
- 868MHz antenna would be used for
reception and power.
- 24GHz antenna for sensing data.
- Antenna sizes to be correct sizes in
contrast with each other.
The design ideas and modeling was inspired by research papers and my supervisor. The main process of the project was to design these 2 antennas on the program CST. Designing, modeling, simulating and testing the antennas on a substrate reprented as a skin model (skin phantom).
Calculations needed for the 868MHz antenna.An R6 monzo data sheet:
Q = wRCRs = 1 / (1 + Q2) * RpCs = (1 + 1 / Q2) * Cp
Calculations needed for 24GHz antenna:Linecalc on a program called ADS for feed width.
Achieved 2 antennas with a good match on a skin model. The antennas had to be tested seperatly due to a splt frequency ship not yet existing for these 2 frequencies. Proving that it could be possible for this technology to exsit and be used for various applications
Results for the 868MHz antenna above and results for the 24GHz antenna below. Showing both antennas working efficiently on a skin model.
