ENGINEERING ANSWER
RFID spans different bands and architectures. An RF reader board, antenna feed and tag substrate have different cost, size and electrical requirements, so they should not receive the same material recommendation.
What to decide before release
Identify the actual operating band and matching constraints. For readers, evaluate power paths and receiver isolation. For antennas, include nearby objects and the mechanical mounting environment in the tuning process.
Checks to put in your design brief
- State the RFID band
- Distinguish reader and tag requirements
- Test in the intended environment
Important distinction
A more expensive laminate is not automatically the best choice for a cost-sensitive tag.
