Well, there is the Moxon Rectangle, Discone, Sloper, Delta Loop, Big
Wheel, Circular Loop, Orthogonal loops with periodic feed, Vee,
Rhombic, Helix, Parabolic Dish, Cone with spiral lip, G String, Surface
fed half sphere, BirdCage, Lazy Vee, Moon Bounce, and a bunch of others
that escape me at the moment...

It would seem that many antenna designers, some of whom would not
recognize a real time vector if it poked them in the eye and then
scrawled a table of Naperian Logarithms on the wall paper, have already
gone ahead without waiting on directions from open minds...
