Single-Band Chip Antenna LPWA λ/4 Board-Mount

Standard

STAF’s SMT chip antenna measures just 9.1 (L) × 4 (W) × 1.2 (H) mm and supports a wide frequency range from 315 MHz to 2.4 GHz—making it one of the most compact antenna solutions available for LPWA-based IoT/M2M devices.

Its ultra-small footprint enables antenna integration in space-constrained designs such as handheld terminals, card-type devices, and other form factors where conventional embedded antennas were previously impractical.

The minimal PCB clearance area required by this chip antenna makes it ideal for compact device architectures. Its small form factor allows engineers to maximize usable board space while maintaining reliable wireless connectivity.

Supplied in tape-and-reel packaging compatible with standard pick-and-place equipment, this antenna supports efficient, high-volume automated assembly—reducing manufacturing cost and accelerating production timelines.

STAF provides dedicated Antenna Optimization Service to support your integration process, including PCB layout review, antenna placement guidance, and impedance matching tuning tailored to your specific device requirements.
