Radientum Oy is an antenna, RF & EMC design, testing, and consulting company. We have the engineers and the tools to bring superior wireless connectivity to your products. We help your product development to be cost-effective and speed up time-to-market, which results in a higher Return-On-Investment (ROI). 
We have served more than 200 customers with experience from over 400 wireless projects. Our engineers can design any compactly integrated antennas from the very first concept innovation through Over-The-Air verification to ready-made prototypes, simulate your signal integrity and fix noise sources in your product.
Our expertise covers a wide range of wireless technologies including WIFI, RFID, NFC, GNSS, Cellular LTE & 5G, Bluetooth, NB-IoT, UWB, LoRa/Sigfox, and many others, from 13MHz to 122GHz. Our laboratories in Finland allow fast, high-quality, and cost-effective testing before certifications. We don’t only deliver results, we provide solutions. 
We believe in delivering high-quality designs and insights using our extensive experience in antenna design as well as modern simulation tools that allow an excellent match between simulations and measurements. This allows our customers to reduce the number of prototyping rounds as antennas no longer need tuning before other tests. Our offering covers everything from first concept studies to production-ready prototypes which means faster development time that leads to reduced costs.
Our specialization is small custom-designed, highly integrated antennas. However, if you don’t have space constraints for your antennas, we can help you select the best “off-the-shelf” solution and integrate it into your device.
