Paul Shuch was working on a phased-array panel antenna for
 SETI work.  I don't know how many elements, but it was
 steered using varactors.  For some environments, this would
 be really nice--no need to build mechanicals to swing a dish
 around.

On the down side, a phased-array patch antenna is potentially a lossy
 thing, so useless for weak-signal work like EME and radio astronomy.
 Unless you have an LNA at every element in the array.  Which maps into
 $$$.
