Heh. Well, it *has* documentation, at least ;)

This is for http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=260384961321&ssPageName=ADME:X:RTQ:US:1123
which is a microwave doppler radar module selling for $5 (+ $13
shipping, as is the way of these things). I find the circuit diagrams
slightly confusing on first inspection, and in particular I still have
no idea whether the module has a built-in antenna or not, but I
present it for your edification (or amusement) anyway.
