Simulation-Based Performance Evaluation of Wire-Grid approach for 3D Printed Antennas: Comparative Analysis and Experimental Validation

The advancements in 3D printing technology have revolutionized the design and fabrication of complex antennas, enabling the development of smaller and lighter designs. However, these changes in physical dimensions necessitate a thorough investigation of the antenna characteristics before large-scale production. Simulation plays a crucial role in the evaluating these characteristics. This research paper focuses on verifying the wire-grid approach for modeling perforated antennas. A perforated horn antenna was modeled using two different wire-grid structures, and the results were compared with those obtained using another software. Additionally, the simulation results were compared with measurements taken from various types of 3D printed antennas. The comparative analysis demonstrates a high level of consistency and highlights the effectiveness of the wire-grid approach in simulating antenna behavior. These findings emphasize the possibility of using wire-grid approach together with the 3D printing technology to evaluate and optimize complex antenna structures. By harnessing the potential of 3D printing technology and simulation tools, researchers and engineers can continue to push the boundaries of antenna design and fabrication, leading to the development of smaller, lighter, and more efficient antennas for a wide range of applications.
