| 摘 要： | 设计了一种由L 波段和C 波段两个反射面天线组成的星载薄膜双频平板抛物面天线及两个天线共面。天线阵面由两层膜面组成，阵列单元直接印制在膜面上。底层膜上全部印刷金属膜，上层膜上印刷L 波段单元。在上层膜面上粘贴软泡沫衬垫，在软泡沫衬垫上印刷C 波段单元，L 波段单元同时用作C 波段单元的反射面。由于平板抛物面天线具有重量轻、成本低等优点，因此无论在军事还是民用都将具有广泛的应用前景。

| Abstract: | The double frequency flat parabolic surface antenna for spaceborne radar was designed, which comprised of twocoplanar L waveband reflecting surface antenna and C waveband reflecting surface antenna. The bottom layer film printed copperfilm, which is the metal ground plane of L waveband flat parabolic surface antenna. The middle layer film printed L waveband flatparabolic surface antenna element, which is also the metal ground plane of C waveband flat parabolic surface antenna. The top layerprinted C waveband flat parabolic surface antenna element. As flat parabolic surface antenna has little weight and prices, it will bewidely applied in military and civil application field. |
