A spiral Radial Line Slot Array (RLSA) Qualification Model (QM) High Gain Antenna (HGA) was designed, fabricated and tested for the DART spacecraft. The antenna operated at the X-band Deep Space Network (DSN) frequencies of 7.2 and 8.4 GHz. The fabricated antenna exceeds the given requirements, agrees well simulations, and has been tested through environments resulting in a TRL-6 design.
