Abstract
Modern geospatial techniques enable the provision of up-to-date imagery to the public through the media and internet. Improvements to earth monitoring satellites, such as SAR, and the very high resolution data received from these satellites, result in very large data files or a wide band pipe required for the transmission to the receiving earth stations. These large bandwidths cannot be provided by the regular allocated slot in XBand. The only way to increase the bandwidth of the downlink is the exploitation of K-Band (25.5–27 GHz). Vertex Antennentechnik (VA) has developed a triband full motion Antenna System with 11.5 meter diameter which incorporates S-, X- and K-Band. In conventional multiband Antennas, it is difficult to optimize Antenna parameters such as aperture efficiency and sidelobe performance in all three bands simultaneously. This paper discusses some advantages and design considerations and highlights the overall performance of a novel triband Antenna system for Remote Sensing (RS) applications which has been commissioned in 2016.
