Wireless power transmission using dipole rectennas made on flexible cellulose membrane

This study reports a wireless power transmission technology using dipole rectenna arrays made on a flexible cellulose membrane. Three flexible dipole rectenna arrays are designed, fabricated and characterised. A rectenna array with nine rectenna elements generates a maximum power of 75 mW with a conversion efficiency of 56%. Detailed fabrication and characterisation of the flexible dipole rectenna arrays are described. This flexible dipole rectenna can be used for biomedical applications.
