Manufacturer of inductive components, PREMO, has announced the KGEA-AF-Series of long-range and ultra-long-range flexible antennas, providing up to five times more H-field than standard antennas up to 2.5 times the mid-range one. Most of the LF antennas in the market has a length 70 to 80mm for standard range, 150 to 170mm for mid-range, 250 to 350mm for long-range and 500 to 700mm for Ultra-Long-Range (Alma core).

A research team led by expert in Magnetism PhDr Manuel Vazquez Head of the Group on ‘Nano-Magnetism and Magnetisation Processes’ in Madrid (CSIC: Superior Council of Scientific Investigations), join with UC3M (Carlos III Madrid University) and Málaga PREMO Innovation Center, have developed a Technology intended for LF emitter antennas in the range of 20 to 134KHz that overcome the limits of conventional ferrite cores that are fragile and brittle and cannot be manufactured reliably in long forms.

After three years of work and more than 1M€ in private and public funding, CDTI: Center for Industrial Technological Development) the team is announcing the first industrial solutions of the new tech.

Premo Nanotech Magnetic Materials allow Long Flexible Emitter Antennae for Automotive Electronics.

The Alma Core Technology for Car Keyless Entry Systems saves installation, cables, electronic drivers and reduce component count with savings per vehicle over 100 USD. The product is designed to be flexible and unbreakable thanks to a combination of Solid Echelons, Polymer Bonded magnetics and High Magnetic Permeability nanowires. 

These flexible core antennas typically meet the AEC-Q200 (specific automotive quality standard) and waterproof specs from IP54 to IP69K.
