由于微带天线低剖面的结构特点,它非常适合用作共形天线。因此共形微带天线理论与技术在近十几年来得到了很快的发展。本文采用国际上近几年来流行的多端口网络模型理论,设计了一种与圆柱体共形的九单元微带串馈线阵,并得到了与理论分析吻合的测试结果。该天线的特点是尺寸小,频带宽,波速窄,主波速有20°扫描角,圆周方向的波速宽度为110°,可作为导弹定向引信系统的探测天线。
Due to the structural features of the low profile microstrip antenna, it is well suited as a conformal antenna. Therefore, the theory and technology of conformal microstrip antennas have been rapidly developed in recent ten years. In this paper, we adopt a multi-port network model theory which is popular in the world in recent years. We design a nine-unit microstrip serial-line array that is conformal to the cylinder. The test results are in good agreement with the theoretical analysis. The antenna is characterized by small size, wide frequency range, narrow wave speed, 20 ° scan angle of the main wave velocity and 110 ° wave width in the circumferential direction, which can be used as the detection antenna of the guided missile directional fuze system.
