研究目的
Investigating the performance of 3D printed horn antennas metallized with a new direct chemical plating method for silver (JET METAL process) compared to standard Cu horn antennas and 3D printed electroplated horn antennas at mm-wave frequencies.
研究成果
The study concludes that 3D printed antennas metallized with the JET METAL technology show comparable performance to conventional technologies in terms of S11 values and gain at 77 GHz. The JET METAL technology offers advantages from an industrial manufacturing point of view.
研究不足
The study is limited to the comparison of three specific types of horn antennas at mm-wave frequencies. The surface roughness of the 3D-printed parts before metallizing and the mechanical mismatch between antenna and waveguide taper could affect the results.
1：Experimental Design and Method Selection:
The study compares three types of WR12 pyramidal horn antennas: a standard Cu electroformed Gain Horn, a 3D printed antenna metallized via electroplating with Cu and an Au finishing layer, and a 3D printed antenna metallized via the JET METAL technology.
2：Sample Selection and Data Sources:
The antennas were designed with specific dimensions and metallization processes.
3：List of Experimental Equipment and Materials:
Vector Network Analyzer (Rohde & Schwarz ZVT 20), Millimeter-wave converter (Rohde & Schwarz ZVA-Z110), and 3D printed antennas.
4：Experimental Procedures and Operational Workflow:
The antennas' performance was evaluated based on S11 parameters and gain measurements.
5：Data Analysis Methods:
The S11 parameters and gain were measured and compared to simulations.
