Description

This 868MHz LoRa antenna is a fundamental RF component designed to enhance the wireless link budget of IoT transceivers. Its ¼-wave monopole design and 50-ohm impedance are engineered to match the output stage of common LoRa modules, ensuring efficient radiated power and improved receiver sensitivity.

With a peak gain of 0.6dBi and a low VSWR profile, it offers a reliable balance between omnidirectional coverage and signal strength, making it a practical choice for deploying sensor networks, asset trackers, and smart agriculture systems across the 868MHz band. The RP-SMA male connector provides a secure, screw-on interface for stable long-term connections.

Key Features

  • Precisely tuned for the 868MHz LoRa and ISM frequency band.
  • Features a low typical Voltage Standing Wave Ratio (VSWR) of ≤1.9 for optimal impedance matching.
  • Compact and lightweight ¼-wave monopole antenna design.
  • Standard 50-ohm impedance ensures compatibility with most RF transceiver outputs.
  • RP-SMA male connector provides a reliable, threaded connection.
  • Robust construction supports an operating temperature range of -20°C to +85°C.

Applications

Frequently Asked Questions

Is this antenna compatible with my LoRa module that has an SMA female port?

No, this antenna has an RP-SMA male connector. It is designed to mate with an RP-SMA female port, commonly found on many consumer routers and some modules. For a standard SMA female port, you would need an antenna with an SMA male connector. Always verify your device's connector type (SMA or RP-SMA) and gender before purchase to ensure a proper physical and electrical connection.

What is the effective range I can expect with this 0.6dBi antenna on a LoRa node?

The effective range depends heavily on transmitter power, receiver sensitivity, environment, and antenna height. With a typical LoRa module (e.g., SX1276 at 14dBm) and this 0.6dBi antenna, you can expect several kilometers in clear line-of-sight conditions. In urban or dense environments with obstructions, the range will be significantly reduced, often to a few hundred meters. For maximum range, ensure the antenna is mounted vertically and has a clear Fresnel zone.

Can I use this 868MHz antenna for 915MHz LoRa operations in the US?

Using an antenna tuned for 868MHz on a 915MHz system is not recommended and will degrade performance. The antenna's VSWR and radiation efficiency will be suboptimal at 915MHz, leading to increased signal reflection, reduced radiated power, and shorter effective range. For operations in the 902-928MHz US ISM band, you should select an antenna specifically tuned and rated for that frequency range to ensure regulatory compliance and optimal link reliability.
