Embedded Antennas – Enabling Efficient and Flexible IoT Solutions

Embedded Antennas – Enabling Efficient and Flexible IoT Solutions

As digital transformation and the Internet of Things (IoT) continue to accelerate, the demand for compact, high-performing wireless solutions is surging. Round Solutions specializes in addressing this need by providing innovative embedded antennas tailored precisely to each device and application.

Embedded antennas integrate directly into devices, delivering robust wireless connectivity without relying on external components. This makes them a key enabler for modern IoT applications across industries.

In this whitepaper, we’ll explain how embedded antennas work, the advantages they offer, and how Round Solutions supports customers in bringing high-performance embedded antennas to life.

2. What Are Embedded Antennas?

Embedded antennas are integral parts of a device’s structure—rather than separate, protruding components. They are typically implemented as:

  • Printed traces on the device’s PCB
  • Flexible antenna modules integrated within the device
  • Antennas directly embedded into plastic housings (e.g., using Laser Direct Structuring – LDS technology)
At Round Solutions, we leverage our in-depth expertise to design and integrate these antennas seamlessly into your product, ensuring optimal performance and reliable connectivity.

3. Key Benefits of Embedded Antennas
