Isotropic antenna for NFC

11 July 2012 Telecoms, Datacoms, Wireless, IoT

Premo has launched a new 3D-coil isotropic magnetic antenna for NFC (near-field communications) applications (13,56 MHz). The antenna has a high surface resistance NiZn ferrite core material (>10 MΩ/mm) and low initial permeability to work at high frequency. This provides very stable performance in a wide range of temperature (-40°C to +85°C).

The 3DC15-HF is offered with 3, 6, 9, 18 and 60 μH inductance values. Users can use these inductance values independently or combine them to produce the standard inductance values of 1, 2, 3, 6 and 20 μH by connecting the three axes in parallel. The antenna’s SMD configuration allows easy integration in an automatic printed circuit board assembly process (lead-free reflow), avoiding handling of the piece that could damage the winding wire.

The 3DC15 series meets the AEC-Q-200 standard for automotive applications, and is suitable for applications in both domestic and industrial environments. The inductance and Q factor have been measured at 13,56 MHz and are suitable for RFID applications with ISO15693 (vicinity: I-CODE) and ISO 14443 (proximity: MIFARE) interface.
