研究目的
To present a wideband endfire antenna co-designed with broadband low-scattering characteristics, utilizing a combination of a metamaterial absorber (MA) absorption and an incident penetration of a frequency selective surface (FSS).
研究成果
The paper successfully presents a wideband low-scattering endfire antenna by combining MA absorption and FSS incident penetration. The design achieves broadband low back RCS from 0.5 to 12.5 GHz and validates the performance through simulation and experimental verification.
研究不足
The RCS-reduction bandwidth and the reflection bandwidth are areas that could be further optimized. Additionally, the impact on radiation performance, such as a slight decrease in realized gain, is noted.
1：Experimental Design and Method Selection:
The design is based on a transmission line model, utilizing a surface waveguide (SWG) to support dual-resonance surface waves for wideband reflection response and endfire radiation.
2：Sample Selection and Data Sources:
A prototype is fabricated and measured to validate the reflection, radiation, and scattering performance.
3：List of Experimental Equipment and Materials:
Includes an AV3618 Vector Network Analyzer for reflection feature measurement and an anechoic chamber for radiation and scattering performance measurement.
4：Experimental Procedures and Operational Workflow:
The SWG is analyzed for its dual-resonance surface waves support, and the MA is integrated with the SWG for low back RCS.
5：Data Analysis Methods:
Full-wave simulation and experimental verification are used to validate the performance.
