Anteenada log-spiral waa anteeno xagal qadiimi ah oo xuduudaheeda cududda birta ay ku qeexan yihiin qaloocyada wareegyada logarithmic. Iyadoo muuqaal ahaan la mid ah wareegga Archimedean, qaab dhismeedkeeda xisaabeed ee gaarka ah ayaa ka dhigaya anteeno madax-bannaan oo run ah.

Hawlgalkeedu wuxuu ku tiirsan yahay qaab-dhismeedkiisa is-kaabaya (birta iyo galoofyada hawadu waa isku mid qaab ahaan) iyo dabeecadeeda xaglaha ah. Gobolka firfircoon ee anteenada ee soo noqnoqoshada gaarka ah waa aag giraan u qaabaysan oo wareeg ah ku dhawaad hal hirar. Sida inta jeer ee hawlgalka is beddelo, gobolkan firfircoon wuxuu si habsami leh ugu socdaa gacmaha wareegyada, laakiin qaabkiisa iyo sifooyinkiisa korantada ayaa ah mid joogto ah, taasoo awood u siinaysa xajmiyeed aad u ballaaran.

Faa'iidooyinka muhiimka ah ee anteenadani waa wax qabadkeeda aadka u ballaadhan (bandwidths ee 10:1 ama ka badan waa wax caadi ah) iyo awooddeeda asalka ah si ay u iftiimiso hirarka wareegta ah. Dib-u-dhaceeda ugu weyni waa faa'iido yar iyo baahida loo qabo shabakad quudin dheellitiran. Waxaa si weyn loogu isticmaalaa codsiyada u baahan hawlgal ballaaran, sida ka-hortagga elektarooniga ah (ECM), isgaarsiinta ballaaran, iyo nidaamyada kormeerka spectrum.
