摘要
常用短波天线的尺寸一般较大,不适用在舰艇、船只和山顶等特殊环境中使用。因此,在不降低性能指标的条件下,需要尽量减小短波天线的尺寸。为此,设计了小型短波宽带有源鞭状天线。结果表明,小型短波宽带有源鞭状天线的性能指标不小于常用的笼形天线,且具有体积小、重量轻、抗毁性强、使用电压低等特点。
Generally, the dimension of antenna at HF band is large that can be not applicable to the removable plantform. In order to reduce dimension of the antenna, a miniature broad band active fragellar antenna is designed in this paper. A prototype of the antenna is produced and its performance is tested. The result show that the anteann designed is of small dimension, light weigth and low voltage, and its performance is better than or equivalent to the cage receiving antenna used in common.
