868/915 MHz i‑FlexPIFA™ Antennas

Under Development

Overview

Our flexible PIFA (patented) antenna design 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. 

Our 868/915 MHz i-FlexPIFA series is for sub-GHz applications like LoRaWAN and 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, expanding the FlexPIFA family offerings. The 868/915 MHz i-FlexPIFA outperforms competitors’ solutions in these orientations.

PIFA antenna technology provides consistent performance across the 868 and 915 MHz ISM bands, always ensuring a solid and reliable connection. 

  • Coverage – 863-870MHz or 902-928MHz Operation 
  • Performance – Exceptional performance across operating frequency 
  • Versatile – Flexible, peel-and-stick adhesive backed antenna for a variety of 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 antennas inside their design.
