摘要: 针对小弹径空空导弹引信收发天线高隔离度的要求,设计基于波导缝隙阵列的前向馈电天线和后向馈电天线,采用弹轴方向收发天线错位布局的结构形式。方向图和隔离度测试结果表明,前向馈电天线和后向馈电天线均实现了空心漏斗形状的方向图,且在1 GHz工作带宽内,收发天线隔离度优于-80 dB, 较常规的天线布局,至少提高了11 dB. 该天线设计和布局实现了引信的高隔离度。

Abstract: In order to solve the high isolation of fuze transmitting/receiving (T/R) antennas for a small calibre air- to-air missile, the feedforward and feedback antennas based on slotted waveguide array are presented, and the dislocation layout of transmitting/receiving antenna is used. The test results show that the feedforward and feedback antennas achieve a funneled radiation pattern, and the isolation of transmitting/receiving antennas throughout 1 GHz bandwidth is less than -80 dB which is improved by about 11 dB compared with the regular antenna layout. The design and layout of antennas meet the requirements of high isolation and compact configuration.

Key words: ordnance science and technology, feedforward antenna, feedback antenna, high isolation, dislocation layout
