What most airplanes have is a "phased array" antenna.  There are several 
different ways to do this but its not just a flat plate.

Airplane radars went to it for several reasons not the least of which is 
smaller sidelobes which are a problems sort of in weather (commercial) and 
bad guy (military) detection.

Its amazing how far aviation radar has come.  WE (my wife and I) have an old 
Cessna called A Bambo Bomber.  It was the first airplane Sky King flew...but 
our particular one served on active duty in WWII as a USN radar trainer for 
the TigerCat.  Inside (when we got it) it had the original intercept radar 
system set up in the back so the back seat radar operators of that era could 
train.

It has taken my wife and I forever to get the plane redone and that includes 
the radar...and authorization to use it for "special purposes".

Its fun to compare it with the one in the F-14 my wife and I fly (seperate 
ones)...which is the TigerCats Grandson.
