FlexPIFA / FlexPIFA 6E Flexible Adhesive-Backed PIFA Internal Antennas

Overview

Ezurio's (formerly Laird Connectivity) FlexPIFA™ antennas (patented) are the industry's first flexible Planar Inverted-F Antennas (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 2.4/5 GHz dual-band FlexPIFA™ is ideal for Wi-Fi applications across both traditional 2.4/5 GHz bands, such as 802.11 'a'. The new 2.4/5/6 GHz tri-band FlexPIFA™ 6E is a true Wi-Fi 6E antenna developed to cover all three Wi-Fi bands 2.4/5/6 GHz (802.11ax standard) in a single, compact format.

All products in the FlexPIFA™ family of antennas 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, 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.

FAQ

Can Ezurio's Flex PIFA be mounted on a metal surface?

No.  That said, by placing a 1.5 mm thick piece of polycarbonate between the metal surface and the antenna, the FlexPIFA can be used.
Detailed placement and recommendations can be found in the Datasheet:
2.4GHz FlexPIFA
Dual-Band FlexPIFA
FlexPIFA 6E

Are Ezurio's antennas UL certified?

Ezurio, generally speaking, does not submit antennas for burn testing so as to be UL certified.  That said, we do use UL-94/V0 compliant materials for specific parts such as a radome.  These parts are identified on the antenna's datasheet.

When do you want to use a FlexPIFA over Flex PCB antenna?

In a cluttered propagating environment, such as a medical suite, office, etc. where there are many metal obstructions.
As a propagating signal encounters an obstruction, the antenna's polarization sense changes and will continue to change as each obstruction is encountered.
The FlexPIFA antenna mitigates this polarization sense issue by providing energy in both vertical and horizontal polarization; thereby, increasing the probability of picking up a useable signal.

What is dBd and dBi and how do you convert from dBd to dBi?

    
dBd is a unit of measure for gain using a dipole as a reference; whereas, dBi uses an isotropic radiator.  To convert from dBd to dBi simply add 2.15 to the dBd value to get the dBi value (e.g. 0 dBd= 2.15 dBi)
