论文摘要
带有改良地面平面的紧凑型准叶天线设计用于片上的整壁雷达（TWR）。拟议的天线中基于插槽的接地平面修饰导致显着的微型化，阻抗带宽增加了44.62％。天线的高定向性为9.02 dBi，前后外侧比率为25.76 dB，为2.4 GHz。基于在现实世界部署方案中的实验，发现所提出的Quasi-Yagi天线的性能与Vivaldi天线和商业式架子（COTS）喇叭天线的性能相当。使用设计的天线成功获得了木制隔板和40厘米厚的砌体壁后面的移动人物的基于光谱图的签名，这证明了准叶族天线对于使用雷达片的便携式应用的适用性。
A compact quasi-Yagi antenna with a modified ground plane is designed for a through-wall radar (TWR) on-chip. A slot-based ground plane modification in the proposed antenna results in significant miniaturization with an increase in the impedance bandwidth by 44.62%. The antenna has a high directivity of 9.02 dBi and a front-to-back ratio of 25.76 dB at 2.4 GHz. Based on experiments in real-world deployment scenarios, the performance of the proposed quasi-Yagi antenna is found to be comparable to that of a Vivaldi antenna and a commercial-off-the-shelf (COTS) horn antenna. Spectrogram-based signatures of a moving person behind a wooden partition and a 40 cm thick masonry wall are successfully obtained using the designed antenna, demonstrating the suitability of the quasi-Yagi antenna for portable applications using a radar-on-chip.
