I'm seeking an experienced RFID tags design engineer to develop UHF and HF designs using ANSYS HFSS software.
Once the demo tag are approved, we will provide , big conract to desgin the antenna
Key Requirements:
- Initial demo file needed for approval
- Contract for extensive antenna design work available upon successful demo
- Chips: NXP UCODE 8, 9; Impinj G2IL, G2IM, M730, M830

Antenna Constraints:
- Inlay thickness: 10um (Aluminum)
- Substrate thickness: 50um (PET)
- Read range: 6m to 13m
- Frequency target: UHF EU Band, optimized read performance

Ideal skills:
- Proficiency in ANSYS
- Experience with RFID antenna design
- Knowledge of UHF frequency requirements and logistics environments

Please provide minimum 2 to 3 demo files for approval. Or else no bid, because last time, some people bid, and didn't get good results, they masked out the results, while send to us, and cheated us .
