I-antenna ye-log-spiral yi-antenna ye-angular yakudala enemida yeengalo zesinyithi echazwa zii-logarithmic spiral curves. Nangona ifana ngokubonakalayo ne-Archimedean spiral, isakhiwo sayo sezibalo esikhethekileyo siyenza ibe "yi-antenna ezimeleyo kwi-frequency."

Ukusebenza kwayo kuxhomekeke kwisakhiwo sayo esizixhasayo (izithuba zesinyithi nomoya ziyafana ngemilo) kunye nohlobo lwayo oluyi-angular kuphela. Ummandla osebenzayo we-antenna kwi-frequency ethile yindawo emile okwesangqa enomjikelezo omalunga nobude be-wavelength enye. Njengoko i-frequency yokusebenza itshintsha, le ndawo isebenzayo ihamba kakuhle kwiingalo ezijikelezayo, kodwa imo yayo kunye neempawu zombane zihlala zingaguquki, nto leyo evumela i-bandwidth ebanzi kakhulu.

Iingenelo eziphambili zale antenna kukusebenza kwayo kwe-ultra-wideband (ii-bandwidth ze-10:1 nangaphezulu ziqhelekile) kunye nokukwazi kwayo ukukhupha amaza ajikelezileyo ane-polarized. Iingxaki zayo eziphambili kukufumana inzuzo ephantsi kunye nesidingo senethiwekhi yokutya elungeleleneyo. Isetyenziswa kakhulu kwizicelo ezifuna ukusebenza kwe-wideband, njenge-Electronic Countermeasures (ECM), unxibelelwano lwe-broadband, kunye neenkqubo zokubeka iliso kwi-spectrum.
