Scott asked about sources for antennas for "3-12 GHz and between 12-21
GHz" which is why I recommended Kent Britain's products. He makes
cheap but effective Vivaldi antennas for those frequency ranges for
about five bucks(!)

They're not printed on Teflon, but for five bucks they're good in a
pinch and probably the best value in microwave antennas around. And
if you need something custom, Kent is extremely reasonable. He must
do it for love, because he can't be making much money on these
innovative designs:

Here's a short theory writeup on Vivaldi antennas:
