Abstract
A near isotropic 3D printed antenna on a cubic structure is presented in this work for the first time. The fully inkjet printed antenna has been realized by a unique combination of 3D inkjet printing of dielectric and 2D inkjet printing of metal. The antenna comprises a 1.5λ0dipole that is wrapped around the cube to achieve a near isotropic radiation pattern. The cube measures 2 cm × 2 cm × 2 cm, where each side of the cube corresponds to only 0.16 λ0(at 2.4 GHz). The cube geometry of the antenna is attractive for wireless sensing applications where it can also act as a functional package for the electronics of the sensor node.
