Use of 3D printing technology for planar antenna constructions

Abstract

The applicability of 3D print technologies for manufacturing of planar antenna substrates having tailored permittivity was considered in the work. The permittivity is known as a parameter that has strong influence on the planar antennae key parameters. The application of 3D print gives the possibility of changing this parameter in the range between its value for air up to the value for homogeneous solid material. The change can be achieved through the change of the filament material and the way of 3D print pattern. The preliminary results of simulations and measurements show that the idea of printing of planar antennae substrate may be interesting alternative from a design engineering point of view.
