I-eriyali ye-log-spiral yi-eriyali ye-angular yakudala enemida yeengalo zesinyithi ichazwa ngamagophe e-logarithmic spiral. Ngelixa ibukeka ifana ne-Archimedean spiral, ubume bayo obukhethekileyo bemathematika buyenza ibe yinyani "i-eriyali ezimeleyo".

Ukusebenza kwayo kuxhomekeke kulwakhiwo lwayo oluzixhasayo (intsimbi kunye nezithuba zomoya ziyafana ngokumila) kunye nobume bayo obuyi-angular. Indawo esebenzayo ye-eriyali kumaza omoya athile yizowuni emile okwesangqa enesangqa esimalunga nobude obunye. Njengoko i-frequency yokusebenza itshintsha, lo mmandla usebenzayo uhamba ngokutyibilikayo ecaleni kweengalo ezijikelezayo, kodwa imilo yayo kunye neempawu zombane zihlala zingaguquguquki, zivumela umda obanzi kakhulu.

Iinzuzo eziphambili zale antenna yintsebenzo yayo ye-ultra-wideband (i-bandwidths ye-10: 1 okanye ngaphezulu ziqhelekileyo) kunye nokukwazi kwayo ukukhupha amaza e-polarized circularly. Imiqobo yayo ephambili yinzuzo ephantsi ngokwentelekiso kunye nemfuno yothungelwano lwesondlo oluntsonkothileyo. Isetyenziswa ngokubanzi kwizicelo ezifuna ukusebenza kwe-wideband, njenge-Electronic Countermeasures (ECM), unxibelelwano lwebroadband, kunye neenkqubo zokubeka iliso kwi-spectrum.
