为了在较宽的频率范围内实现旋转对称的光束、低交叉极化分量和紧凑的尺寸，本文提出了一种新型双频喇叭，该喇叭由锥形部分、同轴凹槽部分和安装在两个部分之间的环形投影组成。介绍了该天线的有效设计过程，分别对两个部分进行了优化。作为设计实例，我们设计了一种紧凑的喇叭天线，在指定的两个频段的7.8 GHz和26 GHz中心频率下，其低交叉极电平均小于- 30 dB。
This paper proposes a new dual-band horn consisting of a tapered section, coaxial grooves section, and a ring projection installed between both sections in order to achieve rotationally symmetric beam, low cross-polarization components, and compact size over a wide frequency range. The effective design procedure for this antenna that optimizes two sections individually is described. As a design example, we present a compact horn antenna with low cross-polar level less than −30 dB at both center frequencies 7.8 GHz and 26 GHz of specified two bands.
