1. Introduction
The patent pending MFX3 ultra-wideband flexible antenna has been designed for NB-
IoT / CAT M1 applications to provide highest efficiency and covers all working
frequencies in the 698-3000MHz spectrum, covering all Cellular, 2.4GHz Wi-Fi, ISM and
AGPS. The antenna is omni-directional, delivered with a flexible body with excellent
efficiencies on all bands, ground independent, with cable and connector for easy
installation.
NB-IoT / CAT M1is a low power wide area (LPWA) technology specifically designed for
IoT and M2M. NB-IoT / CAT M1 technology offers lower maintenance cost, with greater
efficiency and reliability by reducing power consumption and providing deeper
penetration compared to standard cellular technologies. It operates on secure mobile
networks making it suited to automotive, smart meter, medical and smart city
applications.
The MFX3 flexible polymer antenna, at 96*21*0.2mm, is extremely thin, and truly
ultra-wideband, with high efficiencies across the bands. It is assembled by a simple
“peel and stick” process, attaching securely to non-metal surfaces via 3M adhesive. It
enables designers to use only one antenna that covers NB-IoT, CAT M1 and all common
LTE frequencies.
The MFX3 is made of durable flexible polymer and is designed to be mounted directly
onto a plastic or glass cover. It offers a peak gain of 5dBi, an efficiency of more than
45% across the bands and is an ideal choice for any device maker that needs to keep
manufacturing costs down over the lifetime of a product. It is ground plane
independent and delivered with a cable and connector for easy connecting to the
wireless module or customer PCB.
Cables and connectors are customizable. Like all similar antennas, care should be
taken to mount the antenna at least 10mm from metal components or surfaces, and
ideally 20mm for best radiation efficiency.
