Process and realization of a three dimensional gold electroplated antenna on a flexible epoxy film for wireless micromotion system

Résumé

The process and realization of a light and low resistive antenna for wireless communications by inductive coupling at 13.56 MHz is presented. The antenna is realized on an insulated substrate made of SU-8 resist in order to prevent the losses due to eddy currents from occurring and to strongly decrease its weight. The conductor is obtained by electroplating 24 μm of gold in a mold of AZ-4562 resist. A Q factor of 29 has been obtained with a maximum of 37 at 19 MHz, for antenna dimensions of 1.5×1.5 cm2. This antenna is the key component for a wireless power supplied microrobot.
