Rugged SMD isotropic antenna targets keyless entry systems

August 31, 2012 // By Julien Happich
Premo has developed a new electromagnetic 3D-coil antenna initially designed for keyless entry applications.

The series 3DC09AOI features three orthogonal coils, side metallization for automatic optical inspection during the soldering process. The pads have a gold finishing for excellent connectivity. The device measures 10.5x9.5x3mm and is highly stable with its windings fully protected by a polymer matrix. It supports a double lead free reflow (270 °C at peak) and operates in the -40°C to 85°C temperature range. The antenna offered in a standard value of L = 14mH with sensitivity greater than 9mVpp / App/m at 20kHz and a Q factor of 6. The antenna is AEC-Q-200 qualified.
