Supplier's Category: All Wireless & RF Engineering: Antenna design and wireless protocol integration
Wireless and RF engineering covers antenna design and wireless protocol integration — Bluetooth, Wi-Fi, LoRa, cellular — including the physical layout choices that determine whether a radio actually performs once it’s inside an enclosure. It’s a specialized subset of electronics design most products only need occasionally.
RF performance is notoriously sensitive to layout and enclosure details that look fine on paper but kill range in practice, so prior hands-on RF work matters more than general electronics experience.
- Ask for measured range/throughput data from a past project, not just simulated antenna patterns
- Confirm access to an anechoic chamber or equivalent for real antenna characterization
- Check experience getting a design through radio certification (FCC, CE RED, etc.), since RF and regulatory compliance are tightly linked

When to bring in RF expertise
RF issues found after enclosure tooling exists are expensive to fix — antenna placement and ground plane design need to be locked well before mechanical design freezes.
Typical sequence
- Antenna and RF layout decided alongside early PCB and enclosure design, not after
- Prototype range and throughput testing before mechanical tooling is committed
- Formal radio certification testing once the design is frozen
