研究目的
To design a compact and low profile Ka band antenna system for an InSAR demonstrator, focusing on high performance, integration, and scalability.
研究成果
The designed Ka band antenna system is compact, has good radiation efficiency, and can be expanded for larger systems. It is suitable for airborne and spaceborne SAR applications requiring high-performance antennas.
研究不足
The paper does not explicitly mention limitations, but potential areas for optimization could include further miniaturization, bandwidth enhancement, or real-world testing constraints.
1：Experimental Design and Method Selection:
The design is based on waveguide slot antennas to achieve low loss and high gain. Simulations are performed using HFSS software to optimize parameters such as slot incline angle and number of elements in sub-arrays.
2：Sample Selection and Data Sources:
The antenna arrays are designed with specific dimensions (e.g., cross-track: 454×
3：8mm2, along-track:
4：4×4mm2) and configurations. List of Experimental Equipment and Materials:
2 Waveguide slot antennas, feed networks, LNAs (receiver components), calibration networks, and metal frame structures are used.
5：Experimental Procedures and Operational Workflow:
The system is modular, with antennas and feed networks integrated via waveguide connections. Simulations in HFSS validate VSWR, gain, and radiation patterns.
6：Data Analysis Methods:
Performance metrics such as VSWR, gain, and aperture efficiency are analyzed from simulation results.
