Developing an effective antenna for IoT applications
Access to the internet is no longer restricted to devices intended for people; things that we may never interact with directly now account for billions of connections and that number is only going up. As vehicles become more connected, we will see increased demand for V2X, the rollout of 5G services will allow even more connectivity, while location-based services are increasing demand for GPS and GNSS functionality. All of these applications rely on wireless communications and, in many cases, they will be hidden from sight, located deep within large machines, vehicles or even structures like bridges.

Antenna design expertise

Molex has been designing, manufacturing and supplying standard and custom integrated antennas for two decades, for mobile and IoT applications in various volumes and for leading device manufacturers around the world.

The Molex antenna product portfolio covers all the major protocols used today, as well as proprietary solutions, with a focus on embedded (PCB mounted) and internal cabled antennas, when performance requirements may dictate their use.

Embedded antennas can be extremely small and manufactured from ceramic and plastic, as well as stamped metal, weighing just a few grams (Figure 4). Cabled antennas can be made using PCBs, both rigid (FR4) and flexible, as well as stamped metal. These capabilities make it simple to find the most appropriate antenna design, whatever the application. Even though they can be made very small and compact, embedded antennas still come with design requirements that, if followed, will help ensure that the antenna performs as the specification demands. Many factors, such as the size of the PCB, its shape and where the antenna is mounted on the PCB can all impact how the antenna performs.
