摘要

摘要: 展寬現(xiàn)有衛(wèi)星通信頻段的帶寬是增大通信容量的有效途徑之一。為將C波段通信接收頻段帶寬展寬為3.625~4.800 GHz，發(fā)射頻段展寬為5.850~7.025 GHz，該文設(shè)計了一種寬頻帶、結(jié)構(gòu)緊湊、雙線極化四端口饋源網(wǎng)絡(luò)系統(tǒng)，通過采用寬帶正交模耦合器與E面?zhèn)缺隈詈蟃-接頭寬帶頻率雙工器，拓寬了饋源網(wǎng)絡(luò)的工作帶寬，由于該工作頻帶超過了標準波導的工作帶寬，網(wǎng)絡(luò)各部件的設(shè)計采取了非標波導，該文設(shè)計了八邊形過渡波導解決了系統(tǒng)各部件在整個頻帶內(nèi)的匹配問題。研發(fā)和測試了該饋源網(wǎng)絡(luò)系統(tǒng)，測試與仿真結(jié)果吻合良好。實測結(jié)果表明，所有端口電壓駐波比小于1.35，插入損耗小于0.5 dB，收發(fā)隔離度大于95 dB。

Abstract: With the development of satellite communication technology, the demand for communication capacity is increasing. Broadening existing communication bandwidth is a key technology of satellite communication antenna. In order to extend the C band satellite communication, covering the receiving band 3.625~4.800 GHz and the transmitting band 5.850~7.025 GHz, a compact broadband four-port dual linear polarization feed network is designed. The broadband characteristics are achieved by employing a broadband orthomode transducer and two identical E-plane side coupling T-junction duplexers. The extended C band exceeds the bandwidth of a standard rectangular waveguide, so an octave bandwidth concept for compact waveguide transitions based on the use of octagonal-shaped sections is presented. A prototype of the feed network is developed. Simulated and measured results show good agreements. Measurements show that, this compact 4-port network provides Voltage Standing Wave Ratio (VSWR) better than 1.35 in all ports, insertion losses less than 0.5 dB, isolation Tx/Rx greater than 95 dB.
