Through-Hole Mount Stamped Metal Antenna

By utilizing an optimized ground plane length, this antenna achieves superior RF performance compared to PCB trace-based designs—delivering wider bandwidth and higher efficiency. With a ground plane length of 110 mm, the antenna achieves approximately –1 dB radiation efficiency in the 920 MHz band, ensuring reliable wireless connectivity for LPWA and IoT applications.

The standard antenna element covers a base frequency range of 814 MHz to 2170 MHz, supporting LTE, LPWA (LoRa, Sigfox—902–928 MHz ISM band), and other sub-GHz IoT/M2M protocols. Pre-certified with widely adopted wireless modules, it enables rapid prototyping and faster time-to-market for your connected device.

What sets STAF apart is our Antenna Optimization Service, where our experienced RF antenna engineers optimize the antenna for each individual device. By fine-tuning the PCB trace pattern, adjusting antenna placement within the enclosure, and calibrating the impedance matching network, we tailor the operating frequency, bandwidth, and radiation efficiency to match your exact application requirements. This hands-on, device-specific optimization—backed by decades of embedded antenna design expertise from mobile handset development—ensures that every device achieves peak wireless performance, from prototype through volume production.

Constructed entirely from stamped metal with no PCB substrate or ceramic elements, this antenna delivers an ideal balance of high radiation efficiency and low per-unit cost. The vertically oriented radiating element—elevated above the PCB ground plane—maximizes radiation efficiency across the wide LTE frequency band, outperforming planar PCB trace designs in both bandwidth and efficiency. This proven combination of performance and cost-effectiveness has made it a trusted choice for smart meters, asset trackers, and a wide range of IoT/M2M deployments.

Designed for through-hole PCB mounting, this antenna provides robust solder joint reliability and strong mechanical retention—ensuring consistent performance even in high-vibration or thermally demanding environments. Widely adopted across a broad range of IoT/M2M devices, it delivers proven long-term reliability in the field.
