Large reflector antennas require struts to mechanically support feeds or sub-reflectors. In many cases, these affect the antenna performance. This paper proposes a comparison between the European Space Agency Deep Space Antennas (DSAs) 3 and 4, in terms of impact of struts on antenna efficiency and sidelobes. The numerical simulations, carried out on the entire antenna model using Physical Optics, indicates that the struts of the new DSA4 can provide a reduced impact due to the different design.

Abstract
Large reflector antennas require struts to mechanically support feeds or sub-reflectors. In many cases, these affect the antenna performance. This paper proposes a comparison between the European Space Agency Deep Space Antennas (DSAs) 3 and 4, in terms of impact of struts on antenna efficiency and sidelobes. The numerical simulations, carried out on the entire antenna model using Physical Optics, indicates that the struts of the new DSA4 can provide a reduced impact due to the different design.File in questo prodotto:
