研究目的
Investigating the design and performance of a compact high gain leaky-wave antenna based on eighth-mode substrate integrated waveguide (EMSIW) resonator in planar environment.
研究成果
The proposed compact leaky-wave antenna based on EMSIW resonator achieves a frequency scanning range of 51° within 8-10 GHz and a peak gain varying from 8 to 11.84 dBi. It offers advantages of compact size, light weight, high gain, and simpler feeding mechanism, making it suitable for various microwave applications at X-band.
研究不足
The antenna's performance degrades at higher frequencies due to the transition into the slow wave region and the emergence of backward spatial harmonics, leading to undesired higher side-lobe levels.
1：Experimental Design and Method Selection:
The design utilizes an eighth-mode substrate integrated waveguide (EMSIW) resonator for compactness and high gain. The antenna is excited by a 50 Ω microstrip line to resonate at the dominant TE110 mode in X-band.
2：Sample Selection and Data Sources:
The antenna is fabricated on Rogers RT/duroid 5880 substrate.
3：List of Experimental Equipment and Materials:
Ansoft HFSS for simulation, Rogers RT/duroid 5880 substrate with specific dielectric constant and loss tangent.
4：Experimental Procedures and Operational Workflow:
The antenna's performance is optimized using HFSS and validated through experiments. The dispersion properties are studied to control the antenna leakage rate and its effect on radiation.
5：Data Analysis Methods:
The performance is analyzed based on reflection coefficient, radiation patterns, gain, and scanning range.
