摘　　要：该文提出了一种带有梯形槽的双脊喇叭天线,天线在口径面和外侧壁引入梯形槽结构,抑制了喇叭外壁上的电流,从而达到降低喇叭天线旁瓣的目的。天线采用3D打印技术,有效地解决了传统方式加工难及一致性差的问题。仿真和实测表明,该天线设计可有效提高天线增益,在工作频带5~10 GHz内天线增益大于10.32 dBi,回波损耗小于-10 dB;在9.6 GHz时峰值增益可达14.61 dBi。将天线喇叭壁设计成空心结构,天线质量减小了74%。测试结果与仿真结果基本一致。A double ridged horn antenna with trapezoidal grooves is proposed in this paper.The trapezoidal groove structure is introduced into the aperture plane and the outer side wall,which can effectively suppress the current on the outer wall of the horn,so as to reduce the sidelobe of the horn antenna.The horn wall of antenna is designed as hollow structure,which reduces the weight of antenna.The antenna adopts the 3D printing technology,which effectively solves the problems of difficult processing and poor consistency in traditional methods.The simulated and measured results show that the proposed antenna design can effectively improve the antenna gain.The antenna gain is higher than 10.32 dBi and the return loss is lower than-10 dB at the operating frequency band of 5~10 GHz and the peak gain reaches 14.61 dBi at 9.6 GHz.Adopting the hollow structure design of the antenna wall can reduce the antenna mass by 74%.The test results are basically consistent with the simulation ones.
