Why Radientum Says the Antenna Isn’t a Component—It’s the System

Antenna Design Is Broken—and Radientum Is Fixing It

Radientum is making a case that should resonate with every engineer building a connected product: if your antenna doesn’t work, you can’t fix it in software.

Radientum doesn’t just treat antennas as components. Instead, they take a system-level approach, treating the entire device—PCB, battery, wires, layout—as the antenna itself. It’s a radical shift in mindset that yields better range, better reception, and far fewer field failures.

Off-the-Shelf Antennas Aren’t the Whole Story

With thousands of off-the-shelf antennas available, it’s tempting to grab one, follow the integration guide, and move on. But as Radientum’s Jukka explains, that “minor” change to placement, ground path, or PCB layout often kills wireless performance.

In Radientum’s model, antenna design doesn’t start after the device is built—it starts with the industrial design sketch. They simulate the entire system before final components are even locked in, adjusting not the antenna itself, but the feeding and grounding architecture to optimize radiating efficiency.

The Antenna Is the Whole System

Radientum’s approach includes:

• Full 3D simulation of PCB and enclosure
• Ground return path optimization
• EMI and noise mitigation
• Matching circuit tuning after prototyping
• Design for global band support (e.g. LTE Cat-M, NB-IoT, GPS)

They also develop reference modules like Omnicora—a proof-of-concept tracker that dynamically tunes its antenna depending on regional frequency bands. It’s a great showcase of Radientum’s smart tuning capabilities for global IoT devices.

Certification-Ready, Satellite-Ready, Future-Ready

Radientum’s approach is now paving the way for devices that can tune themselves to LTE, GPS, and even satellite-based NTN (Non-Terrestrial Networks)—all without changing the radiator.

This allows customers to:

• Launch smaller, smarter global devices
• Add NTN or 5G NR capability via firmware
• Eliminate antenna design failures during certification
• Reduce reliance on RF expertise in-house
