摘要
研究了一种短波段新型小尺寸折叠伞锥天线的空间辐射特性 ,讨论了E面方向图空间俯仰角域的辐射抑制特性 ,给出了空间辐射场的计算结果。结果表明 :所提出的新型天线结构 ,尺寸小 ,在宽频带范围内能有效抑制天线的天波辐射。
The radiation pattern of a new umbrella monopole antenna was simulated numerically, and the radiating or receiving zero field in some spatial range of E plane pattern of the antenna was discussed. It can be concluded from the numerical results that the proposed umbrella monopole antenna is a small size short wave antenna, and has some characteristics to suppresses the sky radiant wave in wide brand frequency.
