Laird: PIFA antenna specifically designed for metal surfaces
Laird is introducing an adhesive-backed flexible antenna designed to be used directly on metal surfaces, enabling the Internet of Things to continue its explosive growth to about 50 billion connected “things” worldwide by 2020. The new, patented antenna, Laird’s mFlexPIFA, is about the size and thickness of a quarter, and is ideal for wirelessly connecting everything from household appliances and automated equipment to medical devices and millions of other items. It is based on a Planer Inverted-F Antenna (PIFA) structure comprised of a mylar antenna element with a foam core, resulting in a low profile, flexible antenna.
The mFlexPIFA antenna can be mounted in a wide range of embedded and external applications with metal surfaces and enclosures. It is available in a 2.4 GHz version for Wi-Fi, Bluetooth, Zigbee, Thread, and general ISM applications. It is also certified for use in selected Laird Bluetooth and Wi-Fi modules.
Importantly, the mFlexPIFA enables the antenna to be placed directly onto metal surfaces without detuning the antenna, which until now has been a major challenge faced by product designers and original equipment manufacturers. It also can be used on curved (concave or convex) metal surfaces to provide greater flexibility in design and superior antenna gain and performance.
