I've seen the same antenna called a "Directional Discontinuity Ring
Radiator" (a rose by any other name). Lots of Google hits for that phrase.

Hi I remember about 30 years ago I needed a directional 2 metre antenna
in a hurry.
Came up with a good old Kiwi #8 fencing wire solution. using an old
ceramic "choc block" connector for the feed I madea 2 element cubical
quad on a bit of 2x1 timber. (Usual formulae out of the ARRL and RSGB
books). Despite being made out of galvanised Iron wire it showed a 7 dB
gain over a dipole at the same height on the local 2M beacon!
