I-Antenna iwuhlobo lwemishini evamile, esetshenziswa kakhulu emsakazweni, kumabonakude, ekuxhumaneni nomsakazo, i-radar, ukuzulazula, izindlela eziphikisana ne-elekthronikhi, izinzwa ezikude, isayensi yezinkanyezi yomsakazo neminye imikhakha.I-antenna iyithuluzi elingasakaza ngempumelelo amaza kagesi liye endaweni ethile emkhathini noma lithole amaza kagesi lisuka endaweni ethile.Noma iyiphi idivayisi edlulisa amasignali ngamagagasi kagesi kufanele iphathe uthi.
Sithola ezimpilweni zethu zansuku zonke ukuthi ukuguqula noma ukwelula i-antenna yomsakazo noma yethelevishini, ngenhloso noma ngokungenhloso, kungathinta ikhwalithi yesiginali.Eqinisweni, ishintsha amapharamitha we-antenna futhi ithinte ukwamukelwa kwamagagasi kagesi.Umthelela wokudlulisa nokwamukela we-antenna uhlobene eduze nemingcele ye-antenna.Lapha sethula amapharamitha ayisisekelo we-antenna.
1. Ibhendi yefrikhwensi yokusebenza
I-antenna ihlala isebenza phakathi kwebanga elithile lefrikhwensi (ububanzi bebhendi), okuncike ezidingweni zenkomba.Ibanga lefrikhwensi elihlangabezana nezidingo zenkomba yimvamisa yokusebenza kothi.Amabhendi efrikhwensi asetshenziswa o-opharetha ayahluka ngamasistimu ahlukene angenawaya.Ngakho-ke, kufanele kukhethwe izimpondo ezinamabhendi afanele.
2. Zuza
Ukuzuza kwe-antenna kubhekisela esilinganisweni sokuminyana kwamandla esiginali ekhiqizwe uthi lwangempela kanye neyunithi yemisebe efanelekile endaweni efanayo esikhaleni ngaphansi kwesimo samandla okufaka alinganayo.Inzuzo ihlobene eduze nephethini ye-antenna.Uma i-lobe eyinhloko iba mncane kanye ne-sidelobe encane, inzuzo iyanda.Ukuzuza kwe-antenna isilinganiso sekhono le-antenna lokukhipha amaza kagesi ngendlela ethile.Kufanele kuqashelwe ukuthi i-antenna ngokwayo ayiwandisi amandla esignali ekhazimulayo, kodwa igxilisa kuphela amandla ohlangothini oluthile ngokuhlanganiswa kwezidlidlizi ze-antenna kanye nokushintsha imodi yokudla.
3. Umkhawulokudonsa
Umkhawulokudonsa ungenye ipharamitha ye-antenna eyisisekelo.I-Bandwidth ichaza ububanzi befrikhwensi lapho uthi olungakhipha ukukhanya noma lwamukele amandla ngendlela efanele.Ama-antenna anomkhawulokudonsa omncane kakhulu awakwazi ukusetshenziselwa izinhlelo zokusebenza ze-broadband.
Empilweni yangempela, ukuze kuhlangatshezwane nezidingo ezingokoqobo ezihlukahlukene, onjiniyela baye basungula izinhlobonhlobo zezimpondo.Okuvame kakhulu yile Antenna ende, ebizwa ngokuthi i-Vertical monopole antenna, noma i-GP antenna, etholakala kumadivayisi aphathwayo.
Lena i-antenna ye-Yagi edumile, eyakhiwe amayunithi amaningi, futhi inokuqondisa okuqinile, imihlahlandlela eminingi, isiqondiso esiningi, inzuzo ephezulu.
Sivame ukubona lolu hlobo lwe-antenna ophahleni lwendlu.Iwuthi oluqondisa kakhulu olusetshenziswa ngokukhethekile ukuxhumana okude.Inobubanzi be-beam obuncane kakhulu kanye nenani lokuzuza eliphakeme kakhulu, elingabizwa nangokuthi i-antenna yokuzuza okuphezulu.
Umumo wezimpondo ziyamangalisa,
Nguwe kuphela ongacabanga,
Awukwazi ukukwenza ngaphandle kwe-MHZ-TD
