Antenna design for wearables
Turn wearable concepts into certified products.
Wireless produce development requires experienced engineers to avoid costly iterations during your development project, especially for wearable products. By using Radientum services for antenna/RF design, testing and EMI/EMC debugging, you are set for success.
Time-to-Market
Find and fix RF/EMI issues early with simulation‑driven design and rapid lab iteration
Cost Optimization
Reduce BOM by utilising exising mechanics or cost efficient manufacturing technologies like PCB trace antennas.
Experience
Proven, Independent Expertise for Wearables
With hundreds of completed projects we know the special challenges of developing wearables like smart watches, earbuds, animal trackers or smart jewelry. We do not lock you into specific manufacturer but instead allow you to optimize the outcome for your business needs.
Space Constraint
Wearable devices are compact and lightweight, requiring every millimeter of internal space to be carefully allocated. Antennas must coexist with batteries, sensors, and processors, leading to potential issues with Electromagnetic Compatibility (EMC) and Radio Frequency (RF) interference (EMI).
Body Interference
The human body, due to its conductive nature, can disrupt antenna signals, causing signal degradation. This “body effect” requires innovative antenna designs to mitigate signal loss and ensure stable connectivity.
Frequency Band Requirements
Wearable devices operate across various frequency bands, including Bluetooth, Wi-Fi, NFC, LTE/5G cellular networks, and GPS, to support multiple functions. These antennas often interfere with each other due to their proximity and the limited space available.
“Project with Radientum gave great results. Communication and collaboration during project was very good. Radientum adapted to all schedule changes which occured at our end.”
“Radientum was able to work with us and our electronics design subcontractor on appropriate level for our knowledge and capabilities (which were not that great in the beginning).”
“Antenna design is the most crucial part of a wireless product and it must be designed by professionals like Radientum who have the right skills, equipment, and technique to analyze faster and provide a solution.”
“Radientum has always done exceptional work on our antenna projects. Their expertise is unmatched. They are very focused and result oriented, and persistent in pursuing the best possible performance.”
"Petri has been incredibly reliable. He's delivered on time and has helped us work through numerous issues during the development phase."
"Quick and prompt action during the project."
We're really happy of the work, deliverables and also that Radientum respect deadlines. It is a long time collaboration. Radientum always took time to answer our questions, even when we asked outside an in-progress activity.
"Defined field of expertise. Clear communication - to the point. Delivered what agreed."
When to engage
ANTENNAS FOR YOUR WEARABLE
Antenna should be considered when device size, materials and use case itself is being developed. When you develop a wearable, delaying a chat with antenna specialist is expensive.
Animal trackers
Regardless of the technology you have chosen, you need the antenna to perform at its best so your connection is reliable and your battery lasts as long as possible. It doesn’t matter if you are tracking a pet running in the woods or a cow far away in the pasture.
Human worn devices (Smartwatches and jewelry)
Whether you are designing a smartwatch, health band, or smart jewelry, you want a strong industrial design without sacrificing quality or cost. You also need to carefully consider specific absorption rate (SAR).
Adaption of new technology
Have you developed BLE devices, but you are now considering Lora? Or maybe you are transitioning to LTE/5G? While each technology has its own benefits, they also have their challenges which are increased with the small formfactors of wearables.
OMNICORA technology demonstrator
Radientum introduces OMNICORA, the smallest LTE-M technology demonstrator powered by Nordic Semiconductor’s nRF9151 SiP. It’s antenna solution, tailored for wearable use cases, is able to meet AT&T operator requirements at the size of only 44 x 26 x 17mm.
Reference project
Extronics – Long distance Communication in process industry
When Extronics, a leader in hazardous area industrial wireless solutions and IoT devices, faced the challenge of developing a wearable LoRaWAN connected worker safety tag for large industrial sites, they knew they needed a reliable partner.
