Abstract: 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.
Key words : wide-band,;V/UHF,;integrated,;airborne antenna;radome

隨著現(xiàn)代信息化作戰(zhàn)體系的逐步建立,,對機(jī)載電子設(shè)備的要求也逐步提高,,超短波電臺是航空電子通信系統(tǒng)中的重要設(shè)備之一,,主要用于飛機(jī)與控制塔臺的空地通信以及飛機(jī)與飛機(jī)空中編隊間的飛行聯(lián)絡(luò)[1]。在教練機(jī)或戰(zhàn)斗機(jī)等機(jī)載平臺,,超短波天線通常安裝于垂尾頂端,,天線輻射特性的好壞將直接影響到整個機(jī)載通信系統(tǒng)的工作性能,設(shè)計出能夠滿足要求的天線是目前工程研究中的重要方向[2],。
目前國內(nèi)外設(shè)計的超短波天線主要采用馬刀天線,,內(nèi)埋于垂尾頂罩內(nèi),天線與天線罩分離設(shè)計并分離測試驗(yàn)證,天線的設(shè)計階段就未考慮垂尾頂部天線罩的復(fù)雜結(jié)構(gòu)對天線輻射性能的影響,,往往單獨(dú)天線在暗室內(nèi)測試性能可以滿足要求,但裝機(jī)后,,由于天線罩的傳輸損耗和罩體與天線之間的耦合造成天線裝機(jī)后的增益下降[3],外場使用過程中經(jīng)常出現(xiàn)通信距離不夠,、通信中斷的現(xiàn)象,。因此,,對天線與天線罩一體化的研究具有重要意義,。
