Applications of wide scan phased array antenna？&a

Hi, friends:

I want to get some information on the applicaitons of wide scan phased array antennas, but it seems that the information I can get is quite limited.
What I can find is that the EO-1 satellite had adopted a wide scan phased array antenna. Do you know any other satellites or spacecrafts or planes or programs that deal with it? Please share them with me.
Thank you!
