3D printed double-ridged horn antenna with dielectric lens for free-space material characterization method

Abstract

This article deals with the design of a 3D printed wideband horn antenna with a dielectric lens for a material characterization workplace exploiting the free-space measurement method. In this work, various ridge profiles placed in the horn antenna are studied for the optimization of the impedance matching in a wide frequency range of 2¬–18 GHz. The workplace consists of two horn antennas with dielectric lenses and a material sample to be characterized.
