RF Circuit Technology - RF PCB application field

RF PCB (Radio Frequency PCB) is widely used in many fields such as television, radio, mobile phone, radar, automatic identification system, etc. The term RFID (Radio Frequency Identification) refers to the use of radio frequency identification signals to identify targets.

RF circuit board

RFID applications include:

ETC (Electronic Toll Collection)

Identification and tracking of railway locomotives and vehicles

Container identification

Identification, authentication, and tracking of valuable items

Target management for commercial retail, healthcare, logistics services, etc

Access Control Management

Animal identification and tracking

Vehicle automatic locking (anti-theft)
