O le ogalaau-spiral antenna o se antenna angular masani ona tuaoi lima u'amea o loʻo faʻamatalaina e ala ile logarithmic spiral curves. E foliga foliga tutusa ma le Archimedean spiral, ae o lona tulaga tulaga ese o le matematika ua avea ai ma "antenna tutoatasi" moni.

O lona fa'agaioiga e fa'alagolago i lona fa'apipi'i fa'atasi (o u'amea ma va o le ea e tutusa foliga) ma lona natura mama. Ole vaega malosi ole antenna ile taimi fa'apitoa ole sone fa'amama mama e tusa ma le tasi le umi ole galu. A'o suia le fa'agaoioiga fa'agaoioiga, e sologa lelei le gaioi o lenei vaega fa'agaoioi i luga o lima li'o, ae o lona foliga ma uiga eletise e tumau pea, e mafai ai ona lautele le bandwidth.

O mea taua o lenei antenna o lona ultra-wideband performance (bandwidths o le 10:1 poʻo le sili atu e masani ai) ma lona gafatia faʻapitoa e faʻaalia ai galu polarized. O ona drawbacks autu e fai si maualalo tupe maua ma le manaomia mo se fesoʻotaʻiga fafaga paleni lavelave. O lo'o fa'aaogaina lautele i talosaga e mana'omia ai le fa'aogaina o feso'ota'iga lautele, e pei ole Electronic Countermeasures (ECM), feso'ota'iga feso'ota'iga lautele, ma faiga e mata'ituina ai alaleo.
