【摘要】：針對(duì)目前多波束切換天線研究中存在的帶寬窄、性能低等問(wèn)題,通過(guò)基于Butler矩陣的饋電網(wǎng)絡(luò)整體結(jié)構(gòu)設(shè)計(jì)和差分移相器快速設(shè)計(jì)方法研究,實(shí)現(xiàn)了具有23%帶寬的寬帶多波束合成網(wǎng)絡(luò);通過(guò)V形縫隙矩形貼片和變形雙π枝節(jié)耦合饋電設(shè)計(jì),展寬了微帶陣列單元天線帶寬;設(shè)計(jì)實(shí)現(xiàn)了4×2個(gè)陣元的寬帶、高增益、多波束移動(dòng)通信天線系統(tǒng),測(cè)試結(jié)果表明:在整個(gè)工作頻段內(nèi)該天線系統(tǒng)四個(gè)波束能夠無(wú)縫覆蓋90°工作扇區(qū),駐波比小于1.5,波束增益達(dá)到16dBi。
[Abstract]:Aiming at the problems of narrow bandwidth and low performance in the research of multi-beam switching antenna, the paper studies the whole structure design of feed network based on Butler matrix and the fast design method of differential phase shifter. A broadband multi-beam synthesis network with 23% bandwidth is implemented. Through the coupling feed design of V-shaped slot rectangular patch and deformed double 蟺 segments, the bandwidth of microstrip array unit antenna is broadened. A 4 脳 2 array element wideband, high gain, multi-beam mobile communication antenna system is designed and implemented. The test results show that the four beams of the antenna system can cover 90 擄working sector seamlessly in the whole operating frequency band. The standing wave ratio is less than 1.5 and the beam gain is 16 d Bi.
