TheGal anteenada xilliyeedka(LPA) waxaa la soo jeediyay 1957 waana nooc kale oo anteeno aan soo noqnoqon lahayn.
Waxay ku salaysan tahay fikradda la midka ah ee soo socota: marka anteenada loo beddelo iyada oo loo eegayo qodob saami qaybsi gaar ah oo τ ah oo weli la siman qaab dhismeedka asalka ah, anteenadu waxay leedahay waxqabad la mid ah marka qodobka f iyo τf. Waxaa jira noocyo badan oo anteenooyin xilliyeed ah, oo ay ka mid yihiin Log Dipole Antenna (LDPA) ee la soo jeediyay 1960-kii waxay leedahay sifooyin baaxad leh oo aad u ballaaran iyo qaab-dhismeed aad u fudud, sidaa darteed waxaa si ballaaran loogu adeegsaday mowjadaha gaaban, mowjadaha ultra-gaaban iyo mikrowave.
Anteenada xilliyeedka loggu waxay si fudud u soo celisaa qaabka shucaaca iyo astaamaha xannibaadda xilliyada qaarkood. Si kastaba ha ahaatee, anteeno leh qaab-dhismeedkan oo kale, haddii τ aan ka yarayn 1, isbeddelka sifooyinkeeda gudaha hal wareeg waa mid aad u yar, sidaas darteed asal ahaan way ka madaxbannaan tahay inta jeer.
Waxaa jira noocyo badan oo anteenooyinkooda xilliyeedka ah, oo ay ku jiraan anteenooyinka log periodic dipole iyo anteenooyinka monopole, anteenooyinka V-qaabeeya resonant log periodic, anteenooyinka xilliyeedka log, iwm, kuwaas oo ay ka mid yihiin anteenooyinka xilliyeedka dipole-ka.
Sida anteeno ultra-ballaaran, daboolka xajmigu waa mid aad u ballaaran, ilaa 10: 1, waxaana badanaa loo isticmaalaa xoojinta calaamadaha, qaybinta gudaha iyo daboolida calaamadaha wiishka. Intaa waxaa dheer, anteenada xilliyeedka logarithmic sidoo kale waxaa loo isticmaali karaa ilo quudin anteenooyinka milicsiga microwave-ka. Maaddaama aagga waxtarka leh uu la wareego inta jeer ee hawlgalka, leexashada u dhaxaysa aagga waxtarka leh iyo diiradda dhammaan guutooyinka inta jeer ee hawlgalka waa in ay ahaato mid ku dhex jirta xadka dulqaadka la oggol yahay inta lagu jiro rakibidda.
RF MISOQaabka RM-DLPA022-7 waa anteeno xilliyeed laba-Polarized ah oo ka shaqeysa0.2 ilaa 2 GHz, Anteenadu waxay bixisaa7dBifaa'iidada caadiga ah. Anteenada VSWR waa 2Nooca. Dekadaha RF anteenadu waa isku xidhaha N-Dumarka. Anteenada waxaa si weyn loogu isticmaali karaa ogaanshaha EMI, hanuuninta, sahanka, faa'iidada anteenada iyo cabbirka qaabka iyo goobaha kale ee codsiga.
