3D-Printed Smooth-Walled Conical Horn Antennas: Manufacturing and Quasioptical Analysis

Wireless power transfer systems may include focusing components to reduce spillover losses. In that case, the implementation of the theory of quasioptics assists in their optimization. This paper presents two 3D printed smooth-walled conical horn antennas used in one such system, at 5.8 GHz. This method results in a high performance, low-cost and lightweight antenna. This discussion includes the design, simulation, manufacturing and experimentation of the horns. Besides testing in an anechoic chamber for analysis of traditional antenna theory quantities, the electric field obtained through electromagnetic simulations is used to study the gaussian beam generated by the horns.
