The OTS antenna measurements activities
Abstract
The Orbital Test Satellite (OTS) uses antennas with two channels for frequency reuse by means of polarization discrimination in the 11 GHz for transmitting and 14 GHz for receiving. The antennas will be both in dual linear and in dual circular polarization. Main requirements for the antennas are efficiency and polarization purity. Furthermore, the pointing of the antenna boresight has to be known with great accuracy. The test range set up for the OTS antennas is discussed and the results obtained are presented. The measurement activities are described for co/cross pattern, gain, and pointing, together with the achieved accuracy. Future improvements of test range and test methods are suggested.
