GNSS antennas connect IoT devices to the Global Navigation Satellite System. GNSS antennas enable accurate location tracking, reliable navigation, and precise timing across a wide range of connected devices. They are therefore becoming increasingly important in the IoT ecosystem, as in areas where cellular coverage is unavailable or unreliable, GNSS is often the only option for location data.

This means that in challenging environments such as remote locations, lack of cellular coverage can be overcome with GNSS antennas. This is especially true when GNSS is supported by RTK positioning and dead reckoning, which help to mitigate GNSS’ own limitations in scenarios where satellite signals are blocked, such as urban canyons. As a result, many IoT applications – such as micromobility, precision agriculture, and mining – now rely on high-precision GNSS solutions.

Careful selection of GNSS antennas is essential to balance low signal loss, high gain, and optimal sensitivity while remaining cost-effective. Performance in harsh environments, such as dense urban areas, or places with electromagnetic interference, is also a key consideration. Antennas designed for robust signal robust help ensure reliable connectivity and positioning, even under demanding conditions.

Each combo antenna supports different technologies and frequency bands, enabling IoT devices to maintain multiple forms of connectivity. In some applications, this ensures always-on connectivity, while in others, the priority may be minimizing cost or maximizing bandwidth.

Combination antennas now offer extensive design possibilities. Designs are only limited by the space available, and we can swap and change internal antenna elements to support any frequency band required to meet bespoke specifications. Although relatively complex to develop, installation is also straightforward because designers only require one mounting point for the entire assembly. And, while cost and complexity have previously limited the potential of this market, this is now rapidly changing.

In recent years, the cost and complexity of producing combo antennas have dropped significantly and they are now accessible to a broader range of users. Manufacturers like Quectel can then reduce development and production expenses by reusing proven form factors at scale. We also lower costs by integrating antenna technologies originally developed for other IoT devices into our combo designs and pass these savings on to customers.
