摘要
设计了一种用于弹体前端的毫米波微带准行波引信天线,此线阵利用微带线自身的损耗特性消除反射波从而省去了匹配负载。仿真结果表明:工作在35 GHz的引信天线可以获得12%的相对带宽,主瓣宽度为190,同时通过调整线阵单元之间间距可以获得弹体子午面任意倾角的方向图,四个这样的线阵天线就可以实现弹体赤道面方向图全向覆盖。
A microsrip quasi-traveling wave fuze antenna is designed, working in millimeter-wave used for missile body fore-end which utilizing the loss characteristic of microstrip line, eliminates the reflected wave without the matched load in the design. The result of simulation indicates, this fuze antenna worked in 35 GHz can obtain 12% of relative bandwidth and main lobe beamwidth of 190. By adjusting the distance between linear array cells, can obtain the directional pattern of random dip angle of meridian plane of missile body. Making use of these four linear array antennas, the covering of directional pattern, of the equatorial plane of the missile body can be realized in all directions.
