Antenna arrays play a very important role into the space industry, in order to achieve directive patterns while guaranteeing the capability to steer the pattern or even to reconfigure it.
Anteral’s X-band DRA is a Directive Radiating Array of seven feed chains. Each single radiating element is composed by a spline horn antenna, a very compact circular waveguide filter that exhibits low losses and a septum polarizer.
Lightness is one of the most highlighted features of this system, which has been especially optimized to be as compact as possible, due to the importance of size and mass for space applications.
The next table shows the specifications for each radiating element:
