Pros and cons of using arrays of small antennas versus large single dish antennas for Deep Space Network

This paper briefly describes pros and cons of using arrays of small antennas instead of large single dish antennas for spacecraft telemetry, command, and tracking (TT&C) - communications and navigation (C&N) - and science support that the deep space network (DSN) normally provides. It considers functionality and performance aspects, mainly for TT&C, though it also considers science. It only briefly comments on the cost aspects that seem to favor arrays of small antennas over large single antennas, at least for receiving (downlinks).
