In this paper, the conceptions of miniaturization of a 3D cubic antenna are presented and discussed. The miniature 3D cubic antenna is designed to operate in the UHF band (902-928MHz) (centered at 915MHz), produce a quasi-isotropic radiation pattern and have a miniaturized size which gives the authors a low cost, light weight and a compact size device for RFID, WSN and RSN applications. The size of this antenna was reduced from 30x30x30mm3 to 13.48x13.48x13.48mm3 that implies a reduction in volume of 90.9279% and a reduction in electrical size of 54.35%.
