3D printing of a patch antenna for 5G network and radio monitoring of UWB signals

The article deals with the fabrication of a patch antenna using 3D printing. PLA material and conductive (copper) spray for coating the conductive parts were used to produce the antenna. The produced antenna has the same parameters as the antenna made from RF/duroid 5880 substrate. The experiment showed that the antenna produced by 3D printing is functional and has good radiation characteristics. In the presented paper, the design, simulation and fabrication of the speckle antenna using two materials (RF/ duroid 5880 and PLA material and surface sprayed with copper spray) are described. The fabricated patch antennas are experimentally tested and their properties are compared.
