研究目的
To enhance the gain of Microstrip Antenna Array using the substrate integrated waveguide (SIW) in (Ku/K) band applications.
研究成果
The integration of SIW in microstrip antenna arrays significantly enhances gain and bandwidth for Ku/K band applications. The 1x2 SIW sawtooth antenna array with inset feed-line achieves a maximum bandwidth of 410 MHz and a gain of 9.27dBi. The simulation results from HFSS and CST show good agreement, validating the design approach.
研究不足
The study is limited to simulation-based validation without physical prototype testing. The performance is evaluated within the Ku/K band applications, and the results may vary in other frequency ranges.
1：Experimental Design and Method Selection:
The study involves designing and simulating a single microstrip antenna and a 1x2 antenna array with SIW integration using ANSYS HFSS. Two designs are considered: one with a microstrip feed-line with SIW and the other with an inset feed-line with SIW.
2：Sample Selection and Data Sources:
The designs are based on Rogers Duro?d TM5880 substrate with specific properties (εr= 2.2 and h = 0.5mm).
3：2 and h = 5mm).
List of Experimental Equipment and Materials:
3. List of Experimental Equipment and Materials: High Frequency Structure Simulator (HFSS) and CST Microwave Studio for simulation, Rogers Duro?d TM5880 substrate.
4：Experimental Procedures and Operational Workflow:
The process includes designing the antenna structures, simulating their performance using HFSS, and validating the results with CST.
5：Data Analysis Methods:
Analysis of reflection coefficient (S11), gain, bandwidth, and radiation patterns to evaluate the antenna performance.
