TheAnteenada Wareegsan ee Loox(LPA) waxaa la soo jeediyay 1957 waana nooc kale oo anteeno aan soo noqnoqonayn oo doorsooma.
Waxay ku salaysan tahay fikraddan la midka ah ee soo socota: marka anteenada la beddelo iyadoo loo eegayo qodob saamiyeed gaar ah τ oo weli la mid ah qaab-dhismeedkeedii asalka ahaa, anteenadu waxay leedahay waxqabad isku mid ah marka factor-ku yahay f iyo τf. Waxaa jira noocyo badan oo anteenooyin xilliyeed ah oo loox ah, kuwaas oo ay ka mid yihiin Antenna Log Dipole (LDPA) oo la soo jeediyay 1960-kii waxay leedahay astaamo aad u ballaaran oo ballaaran iyo qaab-dhismeed fudud, sidaa darteed si weyn ayaa loogu isticmaalay xargaha mowjadaha gaaban, mowjadaha aadka u gaaban iyo kuwa microwave-ka.
Anteenada joogtada ah ee looxa ayaa si fudud u soo celisa qaabka shucaaca iyo astaamaha iska caabinta marmar. Si kastaba ha ahaatee, anteenada leh qaab-dhismeed noocaas ah, haddii τ uusan aad uga yarayn 1, isbeddelka astaamaheeda hal wareeg gudahiisa aad ayuu u yar yahay, sidaas darteed asal ahaan waa ka madax bannaan tahay soo noqnoqoshada.
Waxaa jira noocyo badan oo anteenooyin wareeg ah oo log periodic ah, oo ay ku jiraan anteenooyinka dipole periodic ah iyo anteenooyinka monopole, anteenooyinka qaabaysan ee log periodic resonant V-shaped, anteenooyinka wareega ee log periodic ah, iwm., kuwaas oo ay ugu badan tahay anteenada dipole periodic ah ee log.
Maadaama anteeno aad u ballaaran tahay, daboolka ballaca waa mid aad u ballaaran, ilaa 10:1, waxaana badanaa loo isticmaalaa xoojinta calaamadaha, qaybinta gudaha iyo daboolida calaamadaha wiishka. Intaa waxaa dheer, anteenada logarithmic periodic waxaa sidoo kale loo isticmaali karaa ilo quudin ah anteenooyinka mikrowave-ka. Maadaama aagga wax ku oolka ah uu la socdo soo noqnoqoshada hawlgalka, kala leexashada aagga wax ku oolka ah iyo diiradda saarista dhammaan xadka soo noqnoqoshada hawlgalka waa inay ku jirtaa xadka dulqaadka la oggol yahay inta lagu jiro rakibidda.
