mFlexPIFA Flexible Adhesive-Backed PIFA Internal Antenna

Overview

New: Dual-Band mFlexPIFA (part # 001-0034)

Laird's mFlexPIFA™ antennas (patented) are the industry's first flexible Planar Inverted-F Antennas (PIFA). Both the 2.4 GHz and dual-band 2.4 GHz/5 GHz mFlexPIFA™ antennas are specifically designed for installation on curved or straight metal surfaces. They deliver strong performance in challenging environments, providing you unmatched flexibility to solve your real-world antenna design challenges.

  • Metal-mount design resists detuning for better performance
  • Small size and adhesive backing provide further mounting flexibility
  • Flexible in concave or convex directions
  • Suitable for plastic, metal, and even body-worn applications

Now available: mFlexPIFA dual-band antenna

FAQ

Are Laird Connectivity's antennas UL certified?

Laird, 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)

Does Laird Connectivity have an embedded antenna that can be mounted on a metal surface?

Yes, the mFlexPIFA can be mounted directly to a metal surface.
