研究目的
To develop a conformal leaky-wave antenna based on a curved rectangular waveguide by tailoring the phase velocity through dielectric filling and adjusting slot parameters.
研究成果
The proposed method successfully forms highly directed radiation from conformal antennas based on slotted waveguides curved in E-plane, using partial dielectric filling for phase shift adjustment. Further optimization is needed for sidelobe levels and beamwidth.
研究不足
The antenna requires significant length for acceptable efficiency, limiting its application for narrow-beam radiation in H-plane. Sidelobe levels are higher than expected, indicating need for further optimization.
