研究目的
Designing a nose-cone conformal substrate-integrated waveguide (SIW) slot array antenna for modern radar applications, focusing on achieving constant wave propagation along the length of conformal SIW and low sidelobe levels (SLLs) with high gain.
研究成果
The proposed nose-cone conformal SIW slot array antenna offers high gain with low SLLs, validated through fabrication and measurement. It demonstrates potential for use in modern radars and on the conical surface of aircrafts and missiles.
研究不足
The study faces challenges in maintaining uniform wave propagation along the length of conformal SIW and achieving desired SLLs. The fabrication tolerances and mounting of RWG on conical platform may cause discrepancies between simulated and measured results.
1：Experimental Design and Method Selection:
The study investigates wave propagation characteristics in doubly curved SIW and reformulates the conventional SIW design for nose-cone conformal SIW. It employs RWG to SIW feeding structure to avoid spurious radiations.
2：Sample Selection and Data Sources:
The design uses a 1 × 6 element-based nose-cone conformal slotted array, comparing it with planar and cylindrical conformal arrays.
3：List of Experimental Equipment and Materials:
The substrate chosen is Rogers RT/Duroid 5880 with specific parameters. The array is projected on a conical surface with defined lower and upper radii.
4：Experimental Procedures and Operational Workflow:
The design involves etching slot elements, drilling, metallization of via holes, and wrapping SIW slot array on the conical surface.
5：Data Analysis Methods:
The study compares simulated and measured return losses and radiation patterns to validate the design.
