Computational Investigation of the DTU-ESA 12 GHz VAST12 Validation Standard Antenna to Identify Features Contributing to the Radiated Field

In this paper, we present a computational model of the DTU-ESA Standard Validation antenna VAST12, and investigate the impact of how different features on the antenna impact the radiation pattern. It is shown that the termination of the central tube, used to mount the antenna, has a significant impa...

Summary:In this paper, we present a computational model of the DTU-ESA Standard Validation antenna VAST12, and investigate the impact of how different features on the antenna impact the radiation pattern. It is shown that the termination of the central tube, used to mount the antenna, has a significant impact on the sidelobe level of the antenna.
