@misc{10481/108491, year = {2025}, month = {11}, url = {https://hdl.handle.net/10481/108491}, abstract = {Global data consumption is experiencing exponential growth, driving the demand for wireless links with higher transmission speeds, lower latency, and support for emerging applications such as 6G. A promising approach to address these requirements is the use of higher-frequency bands, which in turn necessitates the development of advanced antenna systems. This work presents the design and experimental validation of a reconfigurable, low-cost leaky-wave antenna capable of controlling the propagation direction of single-, dual-, and triple-beam configurations in the FR3 frequency band. The antenna employs slotted periodic patterns to enable directional electromagnetic field leakage, and it is based on a cost-effective and simple 3D-printing fabrication process. Laboratory testing confirms the theoretical and simulated predictions, demonstrating the feasibility of the proposed antenna solution.}, organization = {MI-CIU / AEI / 10.13039/501100011033 / FEDER, UE (Proyecto PID2024-155167OA-I00)}, organization = {MCIN / AEI / 10.13039/501100011033 – European Union NextGenerationEU/PRTR (Proyecto PID2020-112545RB-C45; Proyecto TED2021-131699B-I00; Proyecto PDC2023-145862-I00)}, organization = {Consejería de Universidad, Investigación e Innovación – Junta de Andalucía (EMERGIA 23-00235)}, publisher = {MDPI}, keywords = {leaky wave}, keywords = {Antenna}, keywords = {periodic structures}, title = {Low-Cost and Fully Metallic Interchangeable Leaky-Wave Antenna Based on 3D-Printing Technology for Multi-Beam Operation}, doi = {10.3390/electronics14234723}, author = {Díaz-Martín, Miguel and Molero Jiménez, Carlos and Martínez-García, Ginés and Baena Molina, Marcos}, }
