项目摘要
Different shapes and types of radio antennas are useful in different circumstances. Horn-shaped antennas are particularly good for when a very accurate calibration of some radio instrumentation (e.g. a radio telescope) is needed, for example. This makes horn antennas very popular for many different applications at microwave frequencies, where they only need to be a few centimetres (or tens of centimetres) across. At low frequencies, a horn antenna would have to be gigantic to work in the same way however. This large size limits their usefulness, particularly for space-based applications where there are restrictive requirements on size and weight of the payloads. We will develop a type of folding antenna that can be packaged up into a relatively small and lightweight form suitable for attaching to a spacecraft, but which folds out into a large horn antenna shape when deployed, suitable for low-frequency applications. This will make it practical to do very high precision radio measurements at low frequencies from space.
不同形状和类型的无线电天线适用于不同的情况。例如,当需要对某些无线电仪器(例如射电望远镜)进行非常精确的校准时,喇叭形天线特别有用。这使得喇叭天线在微波频率的许多不同应用中非常受欢迎,它们的宽度只需几厘米(或几十厘米)。然而,在低频下,喇叭天线必须很大才能以同样的方式工作。这种大尺寸限制了它们的实用性,特别是对于有效载荷的尺寸和重量有限制性要求的太空应用。我们将开发一种折叠天线,它可以封装成相对较小且重量轻的形式,适合连接到航天器上,但在部署时折叠成大喇叭天线形状,适合低频应用。这将使在太空低频下进行高精度无线电测量成为现实。
