3-D Printed Monolithic GRIN Dielectric-Loaded Double-Ridged Horn Antennas
Hoel, Karina Vieira; Ignatenko, Maxim; Kristoffersen, Stein; Lier, Erik; Filipovic, Dejan (2019-09-06)Monolithic integration of 3-D printed gradient index (GRIN) dielectric loading with a double-ridged rectangular horn standard gain horn (SGH) and its impact on antenna performance are demonstrated. Results show that the ... -

Characterization of Variable Density 3D Printed Materials for Broadband GRIN Lenses
Hoel, Karina Vieira; Kristoffersen, Stein (2017)In this work we design, simulate, manufacture and measure blocks made of variable density plastic. The density is controlled through varying the size of small cubes at the intersections of a fine grid. This structure is ...
