doi:10.3969/j.issn.1000-1093.2016.11.025

Abstract

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
