I-antenna ye-log-spiral iyi-antenna ye-angular yakudala enemingcele yengalo yensimbi echazwa ngama-logarithmic spiral curves. Nakuba ifana ngokubonakalayo ne-Archimedean spiral, isakhiwo sayo esiyingqayizivele sezibalo senza kube "yi-antenna engaxhomekile kumaza."

Ukusebenza kwayo kuncike esakhiweni sayo esihambisanayo (izikhala zensimbi nomoya ziyafana ngesimo) kanye nohlobo lwayo oluyi-angular kuphela. Indawo esebenzayo ye-antenna ku-frequency ethile iyindawo emise okwendandatho enomjikelezo ongaba yi-wavelength eyodwa. Njengoba i-frequency yokusebenza ishintsha, le ndawo esebenzayo ihamba kahle ezingalweni ezijikelezayo, kodwa isimo sayo kanye nezici zikagesi zihlala zinjalo, okuvumela i-bandwidth ebanzi kakhulu.

Izinzuzo ezibalulekile zale antenna ukusebenza kwayo kwe-ultra-wideband (ama-bandwidth angu-10:1 noma ngaphezulu avamile) kanye nekhono layo elingokwemvelo lokukhipha amagagasi ahlukaniswe ngendilinga. Izithiyo zayo eziyinhloko ukutholakala okuphansi kanye nesidingo senethiwekhi yokuphakelayo elinganiselayo eyinkimbinkimbi. Isetshenziswa kabanzi ezinhlelweni zokusebenza ezidinga ukusebenza kwe-wideband, njenge-Electronic Countermeasures (ECM), ukuxhumana kwe-broadband, kanye nezinhlelo zokuqapha i-spectrum.
