I-antenna
Inzuzo ephezulu ye-L-Band ye-Antenna ye-Spiral / i-Antenna ye-Helical
iinkcukacha zemveliso
I-eriyali eyi-helical/i-eriyali eSpiral luhlobo olukhethekileyo lwe-eriyali enokusasaza kwaye ifumane imiqondiso ye-electromagnetic ejikelezayo ejikeleza esithubeni. Olu hlobo lwe-eriyali ludla ngokusetyenziswa kwizikhululo ezisemhlabeni kunxibelelwano lwesathelayithi kwaye lwenziwe ngeentsimbi ezijikelezayo ezineempawu ezintle zokuqhuba. Idla ngokutyiswa ngentambo ye-coaxial, apho ucingo olungundoqo lwentambo ye-coaxial ludityaniswe kwelinye icala locingo olujikelezayo kwaye umqhubi wangaphandle uqhagamshelwe kumnatha wentsimbi osekelwe phantsi okanye ipleyiti. Iimpawu zemitha ye-eriyali ejikelezayo inxulumene ngokusondeleyo kwisangqa se-spiral yayo: xa i-circumference incinci kakhulu kunobude be-wavelength, ulwalathiso oluphambili lwemitha luyi-perpendicular axis spiral; xa i-circumference isondele kwi-wavelength, i-radiation enamandla kakhulu ibonakala kwicala le-spiral axis.
Ii-eriyali ze-Helical/Ii-eriyali eziSpiral zinezi mpawu zilandelayo:
- Imitha igxininiswe kakhulu kwicala le-antenna.
- Iyakwazi ukuvelisa amaza e-circularly polarized, ukumelana ngokufanelekileyo nemiphumo ye-multipath kunye nokuphazamiseka komqondiso.
- Ukusasazwa kwangoku kwi-antenna kubonisa ukuma kwamaza okuhamba, okunceda ukufezekisa umphumo ofanayo we-radiation.
- I-impedance yegalelo isondele ekuchaseni okucocekileyo, okwenza kube lula ukuyila kwenethiwekhi ehambelanayo kunye nokuphucula ukusebenza kakuhle.
- Ineempawu zebroadband kwaye inokugcina ukusebenza okusebenzayo kwemitha ngaphakathi koluhlu olubanzi lwamaza.
Ngenxa yokuphazamiseka kweempawu zabo ezisicaba, ukusebenza kwesetyhula okugqwesileyo, kunye nokuphela komlilo kunye namandla omlilo osecaleni, ii-eriyali ze-helical zisetyenziswe ngokubanzi kwiinkalo ezininzi ezinje nge-aerospace, i-meteorology, indawo, kunye nonxibelelwano lonxibelelwano. Ngophuhliso oluqhubekayo lwetekhnoloji yonxibelelwano olungenazingcingo, ukusebenza kombane okuphezulu kwee-antenna ze-helical kulindeleke ukuba kubanike usetyenziso olubanzi kunye nendawo yophuhliso kwixesha elizayo.
