摘要

本文提出了一种工作在E波段和X波段的新型双频喇叭天线。辐射部分是一个喇叭天线阵列,由一个新近提出的基于带隙波导的h面EBG喇叭天线和两个金字塔喇叭天线组成。高频段通过中h面EBG喇叭天线辐射,低频段通过整个阵列辐射。仿真结果表明,在目标工作频率范围内,反射系数小于−10 dB,增益大于16dBi。双频喇叭具有良好的波束宽度均衡性能,在E波段和X波段误差均在$\pm 10^{\circ}$以内。

A Novel Design of Dual-Band Horn Antenna with Large Frequency Ratio
In this paper, a novel dual-band horn antenna operating at E band and X band is proposed. The radiation section is a horn antenna array consists of an H-plane EBG horn antenna based on band gap waveguide proposed recently and two pyramid horn antennas. The high band is radiated through the middle H-plane EBG horn antenna while the low band is radiated through the whole array. The simulation results show that within the operating frequency of interest, reflection coefficients are less than −10 dB and the gains are higher than 16dBi. The dual-band horn exhibits good beam-width equalization performance with an error within $\pm 10^{\circ}$ in both E band and X band.
