Low Profile GRIN Lenses With Integrated Matching Using 3-D Printed Ceramic
IEEE OPEN JOURNAL OF ANTENNAS AND PROPAGATION, 4, 12–22.
author keywords: Lenses; Permittivity; Apertures; Horn antennas; Ceramics; Three-dimensional displays; Reflection; Horn; GRIN lens; high permittivity ceramic; quarter wavelength matching; tapered matching; unit cells; 3D print
TL;DR:
This paper investigates a shortened horn antenna with high gain that is enabled by a 3D-printed gradient index (GRIN) lens composed of high permittivity zirconia and results show good agreement with simulations, including gain performance equivalent to a horn of 2.4x longer length.
