|
Abstract:
文章设计了一款工作于K/Ka频段的帽形馈源及宽带馈电网络，并将其作为照射器应用于0.8米标准环焦反射面。测试结果显示，该天线在17.7~21.2 GHz、27.5~31 GHz电压驻波比均小于1.4:1，天线效率大于65%，第一副瓣电平优于？14.9 dB。
This paper designs a hat-shaped feed operating in the K/Ka frequency bands along with broadband feeding networks, which are used as illuminators for a 0.8-meter standard ring-focus reflector. The test results show that the antenna achieves a voltage standing wave ratio of less than 1.4:1 in both the 17.7~21.2 GHz and 27.5~31 GHz frequency ranges, with an antenna efficiency greater than 65% and a first sidelobe level better than ？14.9 dB.
