How to choose the right antenna for your wireless module 

Choosing the right antenna for a wireless module is among the most critical stages of IoT device design. It's also frequently misunderstood, or treated as an afterthought - which can seriously hinder the success of any device. Even with a well-chosen module, poor antenna pairing can lead to reduced range, unstable connectivity, failed certification, and costly redesigns. Even the best-performing module will fail to meet expectations when paired with an unsuitable antenna or integrated incorrectly. Engineers should therefore consider antenna design constraints as early as possible to achieve optimal performance. In this Masterclass, we offer a practical guide to selecting the right antenna for your module.  

Optimal module and antenna pairing based on application, form factor, interface and certification

Our focus will be on application requirements, form factor constraints, and regulatory considerations in pairing antennas with modules. We'll compare common RF interface options - including integrated antennas, micro-coax connectors, and RF pins - and explain what each means for real-world performance and manufacture. You’ll learn about practical integration topics such as ground plane requirements, enclosure effects, placement and tuning. We'll also cover the impact of enclosure materials, ground planes, cable routing, and antenna placement on overall RF performance. Certifications are another critical factor. Antenna choice can directly affect whether a module’s existing certifications remain valid, or if additional testing is required. Output power, antenna gain, cable losses, and antenna placement can all influence compliance outcomes, making early antenna decisions essential. 

This session is for engineers designing connected products who want to make informed decisions early in the process. Choosing the right antenna means understanding interface trade-offs, navigating form factor constraints, avoiding layout mistakes, and balancing wireless performance with mechanical and regulatory requirements. Reduced risk, improved RF performance, and shorter time-to-market are the rewards. Join us to make the most informed decisions possible when pairing antennas with modules in your next IoT project.
