i-FlexPIFA™ Series Inverted Flexible PIFA Antennas

Recommended for New Design (RND)

Overview

This industry-first inverted FlexPIFA™ (i-FlexPIFA™) antenna design (patented) delivers strong performance in challenging environments, providing you unmatched flexibility to solve your real-world antenna design challenges. Designed for rapid integration into space-constrained devices and housings, the flexible, adhesive backed antennas are available with MHF1 and MHF4L connector options. 

The i-FlexPIFA series is designed with the radiating element facing outward when adhered to a plastic enclosure interior. This orientation gives more flexibility by granting different mounting options, like the underside of an enclosure. The i-FlexPIFA outperforms competitors’ solutions in these orientations, expanding the FlexPIFA family offerings.

We offer a range of i-FlexPIFA antennas including our latest, the i-FlexPIFA Mini. It brings our innovative inverted PIFA technology to even more space-constrained enclosures, offering outward-radiating 2 dBi performance at a tiny 35.9 x 11 mm footprint. 

i-FlexPIFA antenna technology provides consistent performance across the 2.4GHz ISM band, always ensuring a solid and reliable connection. 

  • Coverage – 2.4GHz-2.48GHz Operation.
  • Performance – Exceptional performance with 3.1 dBi gain and 2.5:1 VSWR, outperforming competitors’ solutions. 
  • Versatile – Flexible, peel-and-stick adhesive backed antenna for a variety of space-constrained IoT devices. 
  • Reliable – PIFA technology is easy to integrate into IoT devices and less likely to detune in proximity of metal or a human body.
  • Quality – Designed and built to exacting specifications.

New Mounting Options

The i-FlexPIFA introduces new mounting options to our popular line of FlexPIFA internal antennas. The i-FlexPIFA is designed to radiate on the adhesive side, meaning OEMs can easily mount directly to the inside of the forward or top-facing part of their enclosure. The i-FlexPIFA is designed to give superior performance and reliability in this orientation and give OEMs another option for mounting wireless 2.4 GHz antennas inside their design.
