- Yintoni inzuzo ye-eriyali?
I-antennainzuzo ibhekiselele kumlinganiselo woxinaniso lwamandla ophawu oluveliswe yi-eriyali yokwenyani kunye neyunithi efanelekileyo yokusasazeka kwindawo enye esithubeni phantsi kwemeko yamandla egalelo alinganayo. Ichaza ngokobungakanani iqondo apho i-eriyali ikhupha amandla egalelo ngendlela egxininisiweyo. Inzuzo ngokucacileyo inxulumene ngokusondeleyo nepateni ye-eriyali. Incinci i-lobe ephambili yepateni kwaye incinci i-lobe yecala, iphezulu inzuzo. Inzuzo ye-eriyali isetyenziselwa ukulinganisa ukukwazi kwe-eriyali ukuthumela nokufumana iimpawu kwicala elithile. Yenye yeeparamitha ezibaluleke kakhulu zokukhetha i-eriyali yesikhululo esisisiseko.
Ngokubanzi, ukuphuculwa kwenzuzo ikakhulu kuxhomekeke ekunciphiseni ububanzi bemitha yemitha ethe nkqo ngelixa kugcinwa ukusebenza kwemitha ye-omnidirectional kwinqwelomoya ethe tye. Ukuzuza kwe-antenna kubaluleke kakhulu kumgangatho wokusebenza weenkqubo zonxibelelwano oluphathwayo kuba lumisela inqanaba lomqondiso kumda weseli. Ukwandisa inzuzo kunokunyusa ukugubungela uthungelwano kwicala elithile, okanye ukunyusa umlinganiselo wokufumana phakathi koluhlu oluthile. Nayiphi na inkqubo yeselula yinkqubo yeendlela ezimbini. Ukwandisa inzuzo ye-antenna kunokunciphisa ngaxeshanye umda wokufumana ibhajethi yenkqubo yeendlela ezimbini. Ukongeza, iiparamitha ezimele inzuzo ye-antenna yi-dBd kunye ne-dBi. I-dBi yinzuzo xa kuthelekiswa nendawo yomthombo we-eriyali, kunye nemitha yemitha kuzo zonke iinkalo iyafana; I-dBd inxulumene nenzuzo ye-eriyali elinganayo dBi=dBd+2.15. Phantsi kweemeko ezifanayo, okukhona ingeniso iphezulu, kokukhona umgama onokuthi amaza kanomathotholo asasazeke.
I-antenna ifumana umzobo
Xa ukhetha inzuzo ye-eriyali, kufuneka imiselwe ngokusekelwe kwiimfuno zesicelo esithile.
- Unxibelelwano lomgama omfutshane: Ukuba umgama wonxibelelwano mfutshane kwaye akukho miqobo mininzi, inzuzo ephezulu ye-eriyali inokungafuneki. Kule meko, inzuzo ephantsi (efana ne0-10dB) inokukhethwa.
RM-BDHA0308-8(0.3-0.8GHz,8 Typ.dBi)
Unxibelelwano lomgama ophakathi: Kunxibelelwano lomgama ophakathi, inzuzo ye-eriyali ephakathi ingafuneka ukuhlawulela i-signal attenuation Q ebangelwa ngumgama wothumelo, ngelixa kuthathelwa ingqalelo imiqobo kwindalo. Kule meko, inzuzo ye-eriyali inokumiselwa phakathiI-10 kunye ne-20 dB.
RM-SGHA28-15(26.5-40 GHz ,15 Isimbo. dBi )
Unxibelelwano lomgama omde: Kwiimeko zonxibelelwano ezifuna ukugubungela imigama emide okanye imiqobo engaphezulu, inzuzo ephezulu ye-eriyali inokufuneka ukubonelela ngamandla omqondiso owaneleyo ukoyisa imingeni yomgama wothumelo kunye nemiqobo. Kule meko, inzuzo ye-eriyali inokumiselwa phakathi 20 kunye ne-30 dB.
RM-SGHA2.2-25(325-500GHz,25 iTyp. dBi）
Ubume bengxolo ephezulu: Ukuba kukho uphazamiseko oluninzi kunye nengxolo kwindawo yonxibelelwano, ii-eriyali zenzuzo ephezulu zinokunceda ukuphucula umlinganiselo wesignali ukuya kwingxolo kwaye ngaloo ndlela uphucule umgangatho wonxibelelwano.
Kufuneka kuqatshelwe ukuba ukunyuka kwe-eriyali inzuzo kunokukhatshwa yimibingelelo kwezinye iinkalo, ezifana nokuqondisa kwe-eriyali, ukugubungela, indleko, njl. imeko. Olona qheliselo lulungileyo kukuqhuba iimvavanyo zentsimi okanye ukusebenzisa isoftware yokulinganisa ukuvavanya ukusebenza phantsi kwamaxabiso ahlukeneyo okufumana eyona nto ifanelekileyo yokuseta inzuzo yendalo.
