Antenna/Radio Matching Technique for Certified Multi-module IoT Devices

To save production costs, simplify software development, accelerate certification cycles, and achieve faster time-to-market, many internet of things (IoT) devices resort to using a module-based design. However, a device involving multiple wireless modules may suffer from antenna/radio frequency issues that can result in failing to obtain standard system certification. This paper demonstrates an antenna matching technique applied to a real-world IoT device where no post-production antenna/matching was permitted to the integrated wireless modules.
