Abstract
We present a design for an active antenna array employing triangular Josephson junction (JJ) sub-arrays as rf oscillator sources. The sub-arrays are kept in sync by coupling to a closed serpentine discrete JJ ladder. Phase shifts are introduced by adding external magnetic flux into the JJ ladders between sub-arrays. Phase shifting distortions are minimized by allowing only two contiguous sub-arrays on any row segment
