Spiral Slot Antenna KD8SRQ on 31/12/20
Good day. There is an ad in the October 2019 "Scientific American" that talks about a SPIRAL SLOT ANTENNA. I did some research (not alot) on this type of antenna and the research mentions effective for 1 thru 30Ghz.

Two Questions: 1) has anyone else heard about this type of antenna? 2) has anyone tried to build one (plans look easy but for HF, the whole article of research was unclear)?

Thank you so much for looking at this.
