FlexNotch is the only adhesive-backed, flexible notch antenna that can be easily custom-trimmed for maximum range within your specific enclosure. Paired with the antenna design expertise offered by Laird Connectivity, FlexNotch provides a simple, repeatable process for optimizing antenna tuning to deliver maximum range for your application.

  • With FlexNotch, tuning for your specific application is as easy as 1, 2, 3:
    • Request a Design Review and provide Laird Connectivity with an enclosure sample
    • Laird Connectivity’s Antenna Design experts use 3D modeling and lab testing to determine optimal antenna length for maximum range
    • Built-in cut lines simplify the production process to consistently adapt antennas for best gain & range OR Order pre-trimmed from Laird Connectivity (MOQ requirements apply)
  • Ability to be flexed in either concave or convex directions without sacrificing antenna performance
  • Small size and adhesive-backing give further mounting flexibility within your product design
  • Perfect for WiFi and Bluetooth solutions

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.

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)

What is Laird Connectivity's product lifecycle EOL and PCN policy?

Laird Connectivity is committed to the long-term supply of all its standard embedded wireless modules and packaged products. Laird Connectivity’s products are specifically designed to meet the needs of the industrial and medical markets, which typically require 7 – 10 years product lifecycle. Although Laird Connectivity can’t guarantee that a component used in our products will not be obsoleted and cannot be reasonably substituted, Laird Connectivity can assure customers we will continue to sell our product when we have customer demand and can obtain the necessary components to build our products.
