Aragtida Anteenada - Kala-goysyada Half-Mowjadda Laalaaban
Debelka laalaaban waa anteeno ka kooban laba gudbiye oo is barbar socda oo ku xiran labada daraf, iyagoo sameeya qaab-dhismeed qaab wareeg ah oo xiran, oo barta quudinta ay ku taal bartamaha. Dhererka guud ee anteenadu waa nus hirar, waana sababta loogu yeero nus hirar laalaaban ...Akhriso wax dheeraad ah -
Aragtida Anteenada - Kala-goynta Half-Mowjadda
Anteeno dipole ah ayaa la gooyaa oo la qaloociyaa si loo helo shucaac hufan. Dhererka guud ee fiilada loo isticmaalo dipole-ka wuxuu la mid yahay nus mowjad (tusaale ahaan, l=λ/2). Noocan anteeno waxaa loo yaqaan anteeno dipole-ka nus-mowjad ah. Faa'iidooyinkeeda awgeed, waa anteenada ugu isticmaalka badan...Akhriso wax dheeraad ah -
Aragtida Anteenada - Fiilooyin
Anteenooyinka siligga ah waa mid ka mid ah noocyada aasaasiga ah ee anteenooyinka. Waa kuwo si fiican loo yaqaan oo si weyn loo isticmaalo. Si aan si fiican u fahamno anteenooyinka siligga ah, aan marka hore eegno khadka gudbinta. Khadka Gudbinta Xariiqda gudbinta, ama siligga, waxay sidataa tamar koronto f...Akhriso wax dheeraad ah -
Aragtida Anteenada - Poynting Vector
Anteenooyinka waxay gudbiyaan ama helaan macluumaadka iyagoo ku faanaya tamarta elektromagnetic-ka. Sidaa darteed, tamarta iyo awooddu waa halbeegyo muhiim ah oo la xiriira hirarkan elektromagnetic-ka ah, waana lama huraan in laga wada hadlo. Mowjadda elektromagnetic-ka waxay ka kooban tahay labadaba garoon koronto iyo...Akhriso wax dheeraad ah -

Qaabka shucaaca ee anteenada, qaybta ugu weyn waxay matashaa iftiinka ugu weyn ee anteenada, kaas oo lagu iftiimiyo tamarta ugu badan uguna xoogga badan. Ballaca waa ballaca xagasha ee daloolka kaas oo inta badan awoodda lagu iftiimiyo. Labada ugu muhiimsan ...Akhriso wax dheeraad ah -
Aragtida Anteenada - Alwaaxyada iyo Kala-fogaanshaha
Cutubkani wuxuu ka hadlayaa xuduudaha fallaadhaha shucaaca anteenada, kuwaas oo naga caawiya inaan fahanno qeexitaannada fallaadhaha. Aagga Fallaadhaha Sida ku cad qeexitaanka caadiga ah: "Haddii xoogga shucaaca P(θ,ϕ) uu ku sii jiro qiimaha ugu sarreeya...Akhriso wax dheeraad ah -
Aragtida Anteenada - Shucaaca Isotropic
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. Qeexitaanka Shucaaca isotropic waxaa loola jeedaa shucaaca ka imanaya isha dhibic...Akhriso wax dheeraad ah -
Aragtida Anteenada - Qaababka Shucaaca
Shucaac waa erey qeexaya xoogga hirarka elektromagnetic-ka ee ay gudbiso ama hesho anteenada. Sawir kasta oo anteeno ah, jaantuska muujinaya astaamaha shucaaca anteenada waxaa loo yaqaan qaabkeeda shucaaca. Iyadoo la eegayo shucaaca p...Akhriso wax dheeraad ah -
Aragtida Anteenada - Meel u dhow Goobta iyo Goobta Fog
Ka dib markii laga dooday xuduudaha anteenada aasaasiga ah cutubkii hore, mowduuc kale oo muhiim ah oo la tixgelinayo waa meelaha u dhow iyo kuwa fog ee anteenada. Xoogga shucaaca ee lagu cabbiray meel u dhow anteenada wuu ka duwan yahay kan lagu cabbiray masaafada. ...Akhriso wax dheeraad ah -
Aragtida Anteenada - Xawaaraha Aasaasiga ah
Cutubkani wuxuu soo bandhigayaa xuduudaha aasaasiga ah ee isgaarsiinta wireless-ka, iyadoo ujeedadu tahay in si fiican loo fahmo doorka anteenooyinka ee nidaamyada isgaarsiinta. Isgaarsiinta wireless-ka waxaa lagu sameeyaa qaab hirarka electromagnetic-ka, taasoo ka dhigaysa mid lagama maarmaan ah in la...Akhriso wax dheeraad ah -
Hagaha Ugu Dambeeya ee Anteenooyinka: Sida Anteenooyinka u Shaqeeyaan
Anteenooyinku waa aalad isgaarsiineed oo aad ugu badan nolosheenna. Si kastaba ha ahaatee, dadka badankiisu si dhab ah uma fahmaan, laga yaabee inay og yihiin oo keliya in loo isticmaalo gudbinta iyo helitaanka calaamadaha.
