Abstract:
In this paper, we present a lightweight 3D printed gradient refractive index (GRIN) lens that enhances a dual-ridge horn antenna gain in the 1 to 7 GHz frequency spectrum. The lens design process utilized optical path length transformation techniques and optimization of ideal focal length and thickness. The GRIN lens was fabricated using variable infill fused de-position modeling. The measured result shows an average gain enhancement of 2.82 dBi across the entire frequency spectrum. Overall, the measured and simulated data demonstrated good agreement. The developed prototype is an example of low-cost, ultrawideband, and directive gain enhancement for amateur radio purposes (emergency communications), directed energy, and high-power microwave systems.
