摘要

本文描述了定向轴对称紧致形喇叭天线的合成。所提出的CAD工具是基于在圆柱坐标下的时域有限差分求解器和遗传算法的结合。采用金属化泡沫三维技术的低成本制造技术在ka波段进行了实验验证。实测结果与数值预测结果非常吻合。在29.5 GHz时，辐射效率高达89%。

Compact shaped horn antennas in metallized foam technology

We describe in this paper the synthesis of directive axis-symmetrical compact shaped horn antennas. The proposed CAD tool is based on the combination between a FDTD solver in cylindrical coordinates and a genetic algorithm. A low-cost fabrication technique using a metallized foam 3-D technology is employed for experimental validations in Ka-band. The measurement results are in excellent agreement with the numerical predictions. Radiation efficiencies up to 89% have been obtained at 29.5 GHz.
