FlexPIFA / mFlexPIFA - mFlexPIFA & FlexPIFA antennas for Wi-Fi and Bluetooth applications

FlexPIFA™ (Flexible Planar Inverted-F Antenna) and mFlexPIFA antennas for 2.4GHz and 2.4/5GHz applications

FlexPIFA Antennas

The FlexPIFA™ (patented) is an industry-first flexible Planar Inverted-F Antenna (PIFA). The 2.4 GHz FlexPIFA™ is ideally suited for use with 2.4 GHz applications such as, Wi-Fi® 802.11 b/g/n and Bluetooth. The dual-band FlexPIFA™ is ideal for Wi-Fi applications across both bands, such as 802.11 'a'.

Both the 2.4 GHz and dual-band 2.4/5.5 GHz FlexPIFA™ deliver strong performance in challenging environments, providing you unmatched flexibility to solve your real-world antenna design challenges. The PIFA design provides consistent performance across a broad array of environments & enclosures - plastic, metal, or even body-worn applications.

With the ability to be flexed in either concave or convex directions, without sacrificing antenna performance, the small size and adhesive backing give further mounting flexibility within your product design.

mFlexPIFA Antennas

The mFlexPIFA™ is the industry-first flexible PIFA (patented) antenna specifically designed for installation on metal surfaces. The 2.4 GHz and dual-band 2.4/5.5 GHz mFlexPIFA antennas can be placed directly on curved or straight metal surfaces and provides the best possible antenna gain and performance. Its small size and adhesive-backing give further mounting flexibility within your product design.
