摘要:
针对现代战场面对小雷达反射面积的目标,无线电引信探测天线需具有高增益、高探测分辨力和测角精度的特点,提出了无线电引信角锥喇叭天线辐射性能改善方法。该方法利用三维电磁仿真软件HFSS15.0建模了一种工作在256 GHz的角锥喇叭天线,并分别基于角锥喇叭天线E面、H面、最大距离差面加载介质透镜以改善天线辐射性能。仿真结果表明,基于H面添加介质透镜后,天线增益提升量最高达1.93 dB,驻波比上升最小为0.211 8,E面旁瓣电平降低了2.59 dB,3 dB宽度减小2.41°,H面旁瓣电平减小了6.34 dB,3 dB宽度减小了1.14°,说明基于H面添加介质透镜的角锥喇叭天线辐射性能更好、透镜尺寸更小、重量更轻,较好地满足了无线电引信对天线的要求。
Abstract:
Aiming at the target with small radar reflection area in modern battlefield, the antenna of radio fuze detection needs high gain, high detection resolution and angle measurement accuracy. A method to improve the radiation performance of the pyramid horn antenna of radio fuze was proposed in this paper. In this method, a corner horn antenna working at 256 GHz was modeled by three-dimensional electromagnetic simulation software HFSS15.0. Dielectric lenses were loaded on the E-plane, H-plane and maximum distance difference plane of the antenna to improve the radiation performance. The simulation results showed that the gain of the antenna is up to 1.93 dB, the standing wave ratio was up to 0.2118, the side lobe level of E plane was down by 2.59 dB, the width of 3 dB was down by 2.41 degrees, the side lobe level of H plane was down by 6.34 dB, and the width of 3 dB was down by 1.14 degrees. Therefore, the horn antenna with dielectric lens loaded on the H-plane had better radiation performance, smaller lens size and lighter weight, which satisfied the requirements of radio fuze antenna.
