When is a PCB antenna the right choice for Bluetooth?

On paper: no BOM cost, no connectors, no extra parts.
In reality: performance depends on integration, not the antenna shape.

Good fit when:
🔹Mechanics are stable
🔹Range requirements are clear
🔹You control PCB layout
🔹Reliability matters long-term

Risky when:
🔹Device is compact or metal-heavy
🔹Mechanics change late
🔹You need accurate ranging (e.g. Channel Sounding)

In the latest blog we break down when PCB antennas make sense and what to evaluate early.

Wireless society runs on antennas you’ll never see – and that’s exactly where Radientum comes in. 📡

This article highlights how our antenna, RF, EMC, and wireless design expertise ends up in all kinds of devices – from smartwatches and wearables to industrial sensors, automotive solutions, positioning systems, and even satellites. As devices get smaller and pack in multiple radios, making everything work together becomes more complex – and that’s the challenge we solve every day.

We don’t guess – we simulate, design, and validate with measurements.
When the antenna works, our customers’ business works.

2025 was about people 🩵

The everyday moments, the events, and the milestones, including Matti’s 5 year mark and the start of our Radientum 10 celebrations.

Thank you to our customers, partners, and community for being part of the journey. We truly appreciate the trust and collaboration, and it was great to meet many of you at Embedded World and other happenings throughout the year.

We have new things brewing for next year, and we are definitely not done celebrating 10 yet 👀

✨ Happy Holidays from the Radientum team ✨

As the year winds down, some of our team will be taking time to relax and recharge over the holidays – because great work must have balance.

We’ll be slowing the pace during the holiday season and returning fully re-energized and all hands on deck in the new year.

Wishing you a peaceful holiday season and a great start to the year ahead.

Bluetooth 6.0 can reach centimeter-level ranging — but only if your antenna design supports it.

Real devices behave very differently from bare PCBs, and factors like group delay variation, device mechanics, and calibration determine how accurate your ranging really is.

Our new Radientum × Metirionic whitepaper breaks down the engineering behind it and shows real measurement examples from integrated devices.

Last Friday was no ordinary day at Radientum—it was Bring Your Kid to Work Day! Our offices in Tampere and Espoo were buzzing with creativity, laughter, and a festive spirit. 🤩

In Tampere, our little helper got us into the holiday mood by decorating the office Christmas tree. The result? A tree that perfectly captures the joy and imagination of the season! 🌟

Meanwhile, in Espoo, future antenna engineers took center stage. Anton designed his very own antenna and even got to see a simulation of his work in action. Talk about inspiring the next generation! 🚀

At Radientum, we know that work and personal life go hand in hand. Days like this remind us of the importance of family, fun, and flexibility. They bring something different to our routines and create memories that last far beyond the workday.

To all the kids who joined us: thank you for making our day so much brighter! We’re already looking forward to the next one. 💙
