I-antenna ye-log-spiral iyi-antenna ye-angular yakudala imingcele yayo yengalo yensimbi ichazwa ngamajika e-logarithmic spiral. Yize ibukeka ifana ne-Archimedean spiral, ukwakheka kwayo okuhlukile kwezibalo kuyenza ibe “uthi oluzimele” lwangempela.

Ukusebenza kwayo kuncike ekwakhekeni kwayo okuzilekelelayo (izikhala zensimbi nomoya ziyafana ngokuma) kanye nemvelo yayo eyi-angular. Indawo esebenzayo ye-antenna kumafrikhwensi athile iyindawo emise okwendandatho enomjikelezo ocishe ube ubude begagasi obubodwa. Njengoba imvamisa yokusebenza ishintsha, le ndawo esebenzayo ihamba ngokushelela ezingalweni ezizungezayo, kodwa ukwakheka kwayo nezici zikagesi zihlala zingashintshi, okwenza umkhawulokudonsa obanzi kakhulu.

Izinzuzo ezibalulekile zale antenna ukusebenza kwayo kwe-ultra-wideband (ama-bandwidths angu-10:1 noma ngaphezulu avamile) kanye nekhono layo elingokwemvelo lokukhipha amaza ajikelezayo ayindilinga. Izithiyo zayo eziyinhloko inzuzo ephansi uma kuqhathaniswa kanye nesidingo senethiwekhi eyinkimbinkimbi yokuphakelayo. Isetshenziswa kakhulu ezinhlelweni ezidinga ukusebenza kwe-wideband, njenge-Electronic Countermeasures (ECM), ukuxhumana kwe-broadband, nezinhlelo zokuqapha i-spectrum.
