Basic Knowledge for Matching Antennas to Different IoT Application Needs
Most IoT hardware such as smart sensors and industrial monitoring modules features small volume and multi-frequency access requirements, pushing FPC and chip-type miniature antennas to become mainstream choices. Common working bands include sub-GHz and 2.4GHz WiFi, which puts forward high requirements for miniaturization and radiation efficiency of antenna structures.Metal enclosure and thick non-conductive housing will significantly attenuate antenna outgoing signals. Matching antenna specifications based on the actual internal installation environment is necessary to guarantee normal wireless data transmission of IoT products.
