In its most basic form the Turnstile antenna is two half-wave dipole antennas that are perpendicular and driven 90 degrees out of phase. For a recent review see Crossed Dipole Antennas: A review (also available here).
Usually when used on Earth's surface the "X" is in the horizontal plane and the radiation linearly polarized, but out-of-plane (up and down) they also radiate, but with circular polarization.
I see reference to the inventor's publication as
- G. Brown, “The turnstile,” Electron., pp. 14–17, Apr. 1936.
- Brown, George (April 1936). "The Turnstile Antenna". Electronics.
and the 1935 patent is US2086976, but when I type those into a search engine I can not find the original paper, presumably in a journal or magazine titled simply "Electronics" in 1936.
I don't even know how to reference the journal, because "electronics journal" returns quite a lot of results.
Question: How can I find the full, complete, and unambiguous citation for the journal paper that I believe Brown published in 1936 that explains the Turnstile antenna?
Through the university's library system I may be able to read the article online once I can zero in on the specific journal, and perhaps with the help of a librarian, but there weren't too many engineering schools here in 1936 so I may not be able to get a hold of a bound copy.
