IEEE International Symposium on Antennas and Propagation and ITNC-USNC-URSI Radio Science Meeting - AP-S/URSI 2024, Florence (Italy). 14-19 July 2024
Summary:
This paper introduces a novel top-metalized Dielectric Resonator Antenna (DRA). The inclusion of top metallization induces a modification in the boundary conditions, resulting in a frequency reduction in the fundamental mode of the DRA. A prototype is designed for the 2.45-GHz WiFi band with a –10-dB bandwidth from 2.40 to 2.51 GHz. The radiation maxima occur in the top and bottom directions, with a gain of 1.81
dBi at 2.45 GHz. The proposed DRA is specifically designed for manufacturing using commercially available materials and additive manufacturing techniques.
Spanish layman's summary:
En este trabajo se presenta una novedosa antenna de resonador dieléctrico (DRA en inglés) con metalizaciones en la parte inferior y superior de la misma. Esto permite disminuir la frecuencia de operación de la antena. Se ha diseñado un prototipo para la banda de WiFi a 2.45 GHz. Además, el diseño está realizado para poder ser fabricado mediante técnicas de fabricación aditiva (impresión 3D) con filamentos comerciales.
