Application Scenario
125kHz LF Antennas in Smart Lock / Access Control
Smart locks and access control readers are extremely space-constrained and metal-rich around the antenna.
Balancing space, metal influence, power consumption and cost is the core of antenna selection here.
What you need to consider
- Prefer compact single-axis antennas with simple matching to the MCU
- For metal doors, validate range and field paths through or around metal
- Design concepts from PREMO KGEA body antennas can inspire door layouts
