Evaluation of a Metal 3D- Printed Corrugated Conical Horn Antenna for the E-band

This document proposes the development, manufacturing, and measurement results of a metal 3D printed corrugated conical horn antenna for the E-band (60 to 90 GHz). After a short introduction to the printing technology, the design process of the antenna is presented. The corrugated design is adapted to be compatible to the additive manufacturing (AM) process. After the printing process, the antenna is investigated in terms of dimensional tolerance and surface roughness. The comparison between simulation and measurement yields good results.
