摘要
设计了一种适用于机载垂尾顶部安装的超短波一体化天线,实现了天线与天线罩结构和性能上一体化。对一体化和分离式两种形式的超短波天线进行了研究,采用曲流和匹配加载技术实现了天线的宽频带工作特性,在工作频带内实测驻波比≤2.5,相较于分离式天线,一体化天线解决了天线与天线罩之间的加载耦合效应而导致天线增益下降的问题,在全频带增益提高了约2 dB,重量降低了1.9 kg,天线性能得到全面提升。
In this paper,a V/UHF integrated antenna suitable for installation on the top of aircraft vertical tail is designed,which realizes the integration of antenna and radome in structure and performance.The integrated and separated V/UHF antennas are studied.The wide-band operating characteristics of the antenna are realized by using the meandering and matching technology.The measured standing wave ratio in the operating frequency band is less than or equal to 2.5.Compared with the separated antenna,the integrated antenna solves the problem of antenna gain reduction caused by the coupling effect between the antenna and the radome.By using the integrated antenna,the gain is increased by about 2 dB in the full band,the weight is reduced by 1.9 kg,and the antenna performance is comprehensively improved.
