Abstract

Electrodynamic simulation based on the finite-element method is used to study characteristics of a plane 2D-periodic antenna array consisting of 32 TEM horns with a feeder. For each of two power dividers in the feeder of the array, the reflection coefficient is less than –25 dB in a frequency interval of 0.3–7 GHz. The antenna array is matched with the feeder system at a level of –10 dB in the in-phase mode for scanning in a sector of 90° in the H-plane (E-plane) with a bandwidth of 19 : 1 (15 : 1).

带馈线的TEM喇叭的2D周期超频范围天线阵列

摘要

基于有限元方法的电动力学仿真用于研究由32个TEM喇叭和馈线组成的二维二维周期天线阵列的特性。对于阵列馈线中的两个功率分配器中的每个，在0.3–7 GHz的频率间隔内，反射系数小于–25 dB。在同相模式下，天线阵列与馈线系统的匹配度为–10 dB，可在H平面（E平面）的90°扇区中以19：1（15:15的带宽）进行扫描。1）。
