Cutubka hore, waxaan ka wada hadalnay qaababka shucaaca. Si si fiican loogu falanqeeyo shucaaca anteenada, waxaa loo baahan yahay dhibic tixraac ah. Shucaaca anteenada isotropic wuxuu buuxiyaa doorkan.
Qeexitaan
Shucaaca isotropic waxaa loola jeedaa shucaaca ka yimaada ilo dhibic ah oo si siman ugu faafa dhammaan jihooyinka, iyadoo leh xoog isku mid ah iyadoon loo eegin jihada cabbirka. Horumarinta qaabka shucaaca anteenada waxaa had iyo jeer lagu qiimeeyaa iyadoo la adeegsanayo shucaaca isotropic tixraac ahaan. Haddii shucaacu u siman yahay dhammaan jihooyinka, waxaa loo yaqaan shucaaca isotropic.
• Ilo dhibic ah waa tusaale ka mid ah hiitarka isotropic. Si kastaba ha ahaatee, shucaaca isotropic-ga noocaas ah waa wax aan macquul ahayn in la gaaro, sababtoo ah anteeno kasta waxay ku faaftaa tamarteeda iyadoo adeegsanaysa xoogaa toos ah.
• Shucaaca isotropic wuxuu asal ahaan la mid yahay shucaaca jihada oo dhan.
•Marka lagu eego 3D, waxay leedahay qaab u eg donut; marka lagu eego 2D, waxay leedahay qaab-sawir-siddeed.
Jaantuska kore wuxuu muujinayaa qaabka shucaaca ee hiitarka isotropic (ama omnidirectional). Jaantuska 1 wuxuu soo bandhigayaa qaabka loo yaqaan donut-ka ee 3D, halka Jaantuska 2 uu muujinayo qaabka loo yaqaan shaxanka sideedaad ee 2D.
Faa'iido
Hiitarka isotropic wuxuu leeyahay faa'iido midnimo, taasoo la micno ah in faa'iidada faa'iidada ay tahay 1 jiho kasta. Marka lagu muujiyo decibels (dB), tan waxaa loo yaqaan faa'iidada 0 dB (eber khasaare).
Awoodda Shucaaca Isotropic-ga ah ee u dhiganta (EIRP)
Sida ku cad qeexitaanka caadiga ah, xaddiga awoodda ay ku faafto anteenada isotropic si loo soo saaro cufnaanta awoodda ugu sarreysa ee lagu arkay jihada faa'iidada anteenada ugu badan waxaa loo yaqaan Awoodda Iftiinka Isku-dhafka ah ee Isku-dhafka ah.
Marka tamarta shucaaca ee anteenada ay ku ururto dhinac ama jiho gaar ah, shucaaca jihadaasna uu la mid yahay awoodda shucaaca isotropic ee anteenada, shucaacan waxaa loogu yeeraa EIRP.
Faa'iido
In kasta oo shucaaca isotropic uu yahay kaliya hal-abuur, haddana wuxuu matalaa shucaaca ugu fiican ee suurtogalka ah ee anteenadu gaari karto. Anteenada noocaas ah waxay leedahay faa'iido ah 3 dBi, halkaas oo 3 dB ay u dhiganto qodob 2 ah, "i"-na ay tilmaamayso tirada badan ee la xiriirta xaaladda isotropic-ga.
Haddii shucaacu uu diiradda saaro xagal gaar ah, EIRP wuu kordhaa marka anteenadu korodho. Faa'iidada anteenadu waxaa ugu fiican in lagu gaaro iyadoo shucaaceeda hal jiho loo saaro.
Awood Shucaac Wax Ku Ool ah (ERP)
Haddii awoodda shucaaca lagu xisaabiyo iyadoo la tixraacayo anteenada dipole-ka nus-hir halkii laga xisaabin lahaa anteeno isotropic ah, waxaa loo yaqaan Awood Radiated Effective (ERP).
ERP(dBW)=EIRP(dBW)−2.15 dBi
Haddii EIRP la yaqaan, ERP waxaa lagu xisaabin karaa iyadoo la isticmaalayo qaacidada kor ku xusan.
