1. Hordhac anteenooyinka
Anteenadu waa qaab-dhismeedka kala-guurka ee u dhexeeya booska xorta ah iyo khadka gudbinta, sida ku cad sawirka 1. Xariiqda gudbintu waxay noqon kartaa qaab xariiqda coaxial ama tube godan (waveguide), kaas oo loo isticmaalo gudbinta tamarta korantada ee isha. anteenada, ama anteenada ilaa aqbalaha.Midda hore waa anteeno gudbisa, tan dambena waa helidanteeno.
Jaantuska 1 Jidka gudbinta tamarta Electromagnetic
Gudbinta nidaamka anteenada ee habka gudbinta ee Jaantuska 1 waxaa u dhiganta Thevenin u dhiganta sida ku cad Jaantuska 2, halkaas oo isha ay ka dhigan tahay koronto-dhaliye ku habboon, xariiqda gudbinta waxaa lagu muujiyaa xariiq leh cillad sifo Zc ah, iyo anteenada waxaa u taagan culeys ZA [ZA = (RL + Rr) + jXA].Iska caabinta xamuulka RL waxay ka dhigan tahay dhaqdhaqaaqa iyo khasaaraha dielectric ee la xidhiidha qaab dhismeedka anteenada, halka Rr ay ka dhigan tahay iska caabbinta shucaaca anteenada, iyo falcelinta XA waxaa loo isticmaalaa in lagu matalo qaybta khayaaliga ah ee xannibaadda la xidhiidha shucaaca anteenada.Marka la eego xaaladaha ku habboon, dhammaan tamarta ay dhaliso isha calaamaduhu waa in lagu wareejiyaa iska caabbinta shucaaca Rr, taas oo loo isticmaalo in lagu matalo awoodda shucaaca anteenada.Si kastaba ha ahaatee, codsiyada la taaban karo, waxaa jira khasaare kaari-dielectric ay sabab u tahay sifooyinka khadka gudbinta iyo anteenada, iyo sidoo kale khasaaraha ay keento milicsiga (is-maandhaaf) u dhexeeya khadka gudbinta iyo anteenada.Iyadoo la tixgalinayo ciribtirka gudaha ee isha iyo iska indha-tirka khadka gudbinta iyo luminta milicsiga (isku-dheellitir la'aanta), awoodda ugu badan ayaa la siiyaa anteenada hoos timaada isku-darka isku-dhafka ah.
Jaantuska 2
Sababtoo ah ismaandhaafka u dhexeeya khadka gudbinta iyo anteenada, mowjadda ka soo ifbaxa is-dhexgalka ayaa kor u qaadaya hirarka dhacdada ee ka imanaya isha ilaa anteenada si ay u sameeyaan hirar taagan, taas oo ka dhigan xoojinta tamarta iyo kaydinta waana qalab caadi ah.Qaabka hirka taagan ee caadiga ah waxa lagu muujiyay xariiqda dhibco leh ee Jaantuska 2. Haddi habka anteenada aan loo qaabayn si sax ah, xariiqda gudbintu waxa ay inta badan u shaqayn kartaa sidii walxaha kaydinta tamarta halkii ay ka ahaan lahayd waveguide iyo qalabka gudbinta tamarta.
Khasaaraha ka dhashay khadka gudbinta, anteenada iyo hirarka taagan ayaa ah mid aan loo baahnayn.Khasaaraha khadka waxaa lagu yarayn karaa iyadoo la dooranayo khadadka gudbinta khasaaraha yar, halka khasaaraha anteenada la dhimi karo iyadoo la yareynayo caabbinta khasaaraha ee ay matalaan RL ee Jaantuska 2. Mowjadaha taagan waa la dhimi karaa, kaydinta tamarta ee khadkana waa la yareeyn karaa iyadoo la is waafajiyo xannibaadda anteenada (load) oo leh cilladda sifo ee khadka.
Nidaamyada wireless-ka, marka lagu daro helitaanka ama gudbinta tamarta, anteenooyinka ayaa inta badan looga baahan yahay inay xoojiyaan tamarta shucaaca ee jihooyinka qaarkood oo ay ku xakameeyaan tamarta shucaaca ee jihooyinka kale.Sidaa darteed, marka lagu daro aaladaha ogaanshaha, anteenooyinka waa in sidoo kale loo adeegsadaa aaladaha jihaynta.Anteenadu waxay noqon kartaa qaabab kala duwan si ay u daboolaan baahiyo gaar ah.Waxay noqon kartaa silig, dalool, balastar, ururin curiye (array), milicsi, muraayad, iwm.
Nidaamyada isgaarsiinta wireless-ka, anteenooyinku waa mid ka mid ah qaybaha ugu muhiimsan.Naqshadaynta anteenada wanaagsan waxay yarayn kartaa shuruudaha nidaamka waxayna hagaajin kartaa waxqabadka nidaamka guud.Tusaalaha caadiga ah waa telefishanka, halkaas oo soo dhawaynta baahinta lagu wanaajin karo iyadoo la isticmaalayo anteenooyin waxqabad sare leh.Anteenadu waa nidaamyada isgaarsiinta waxa indhuhu u yihiin aadanaha.
2. Kala soocidda anteenada
Anteenada geesku waa anteenada qorshaysan, anteenada microwave-ka oo leh qayb wareeg ah ama leydi ah oo si tartiib tartiib ah u fureysa dhamaadka waveguide.Waa anteenada microwave-ka ee ugu isticmaalka badan.Goobta shucaaca waxaa lagu go'aamiyaa xajmiga geesaha daloolka iyo nooca faafinta.Waxaa ka mid ah, saameynta derbiga geesku ku leeyahay shucaaca waxaa lagu xisaabin karaa iyadoo la adeegsanayo mabda'a kala-soocidda joomatari.Haddii dhererka geesku aanu isbeddelin, cabbirka daloolka iyo faraqa wajiga quadratic-ga ayaa kordhin doona korodhka xagasha furitaanka geeska, laakiin faa'iidada ma beddeli doonto cabbirka daloolka.Haddii band soo noqnoqda ee geesku u baahan yahay in la ballaariyo, waxaa lagama maarmaan ah in la yareeyo milicsiga qoorta iyo daloolka geeska;milicsiga ayaa yaraan doona marka xajmiga daloolka uu kordho.Qaab dhismeedka anteenada geesku waa mid sahlan, qaabka shucaaca sidoo kale waa mid fudud oo sahlan in la xakameeyo.Waxaa guud ahaan loo isticmaalaa anteeno jiho dhexdhexaad ah.Anteenooyinkooda gees-ka-soo-baxa leh ee baaxadda ballaaran, lugaha dhinac hoose iyo waxtarka sare ayaa inta badan loo adeegsadaa isgaarsiinta is-dhaafsiga microwave-ka.
