Diidoole 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 anteeno dipole laalaaban oo nus hirar ah.
Kala duwanaanshaha soo noqnoqda
Anteenada badh-hirka ah ee isku laaban ee labanlaaban waxay ku shaqeysaa inta jeer ee u dhaxaysa 3 kHz ilaa 300 GHz, waxaana inta badan loo isticmaalaa qaataha telefishanka.
Qaab-dhismeedka iyo Mabda'a Hawlgalka ee Kala-soocidda Half-Mowjadda Laalaaban
Noocan anteenada waxaa badanaa loo isticmaalaa iyadoo lala kaashanayo anteenooyinka safka si loo kordhiyo iska caabinta gelinta ee barta quudinta. Codsiga ugu caadiga ah waa anteenada Yagi. Jaantuska hoose wuxuu muujinayaa anteeno isku laaban oo nus-hir ah.
Marka la barbardhigo anteenada dipole-ka caadiga ah, anteenada dipole-ka ee la laabay waxay soo bandhigaysaa kontaroole barbar socda oo dheeraad ah (tusaale ahaan, silig ama ul kale). Iyadoo la dhigayo dhowr kontaroole oo barbar socda oo leh dahaadh dhexdooda ah, anteeno nooca safka ah ayaa la samayn karaa.
Jaantuska hoose wuxuu muujinayaa mabda'a hawlgalka ee anteenada dipole-ka ee nus-hir laalaaban marka la kacsan yahay.
Haddii dhexroorka gudbiyaha ugu weyn uu la mid yahay kan gudbiyaha barbar socda ee ku jira dipole-ka la laabay, iska caabbinta barta quudinta ee anteenada waxay ku kordheysaa afar (laba jibbaaran). Kordhintan iska caabbinta quudinta ayaa ah sababta ugu weyn ee anteenada dipole-ka la laabay si weyn loogu isticmaalo. Sababtoo ah dhismaheeda laba-lead, iska caabbinta caadiga ah waa qiyaastii 300 Ω.
Habka shucaaca
Qaabka shucaaca ee dipole-ka laalaaban ee nus-hir-hir-laalaaban wuxuu la mid yahay kan anteenada dipole-ka nus-hir-hir-laalaaban. Jaantuska hoose wuxuu muujinayaa qaabka shucaaca jihada oo dhan ee anteenada dipole-ka nus-hir-laalaaban.
Anteenada dipole-ka ee nus-hir-laaban ayaa loo isticmaalaa codsiyada halkaas oo loo baahan yahay wareejinta awoodda ugu badan iyo halka loo baahan yahay iska caabin sare.
Kala-soociddan laalaaban waa curiyaha ugu weyn ee shucaaca ku jira anteenada Yagi. Jaantuska hoose wuxuu muujinayaa anteeno Yagi ah (oo si faahfaahsan looga hadli doono hadhow). Anteenadan, barta quudinta waxaa lagu xirayaa dipole-ka laalaaban oo ah qaybta ugu muhiimsan. Tobankii sano ee la soo dhaafay, noocan anteenada ah waxaa si weyn loogu isticmaalay soo dhaweynta telefishanka.
Kuwa soo socda waa faa'iidooyinka anteenada dipole-ka ee badh-hirka ah ee laalaaban.
1. Waxay heshaa calaamado dheellitiran.
2. Waxay qabataa calaamadaha la rabo ee ka imanaya xarig gaar ah oo soo noqnoqonaya iyada oo aan lumin tayada.
3. Diidoorka laalaaban wuxuu kordhiyaa xoogga calaamadda.
