I-Antenna yePolarized Feed ejikelezayo kabini eyi-8 dBi Type. Gain, 26.5-40GHz Frequency Range RM-DCPFA2640-8

Inkcazo emfutshane:

Imodeli ye-RF MISO i-RM-DCPFA2640-8 yi-antenna ye-polarized feed ejikelezayo kabini esebenza ukusuka kwi-26.5 ukuya kwi-40 GHz, i-antenna inika i-8 dBi typical gain. I-antenna i-VSWR <2.2. Ngokudityaniswa kwe-dual coaxial, i-OMT, i-waveguide, i-feed esebenzayo yokudlulisela ngokuzimeleyo kunye nokwamkela i-dual circular polarization iyafezekiswa. Ifanelekile kakhulu kwiiyunithi ze-array ezingabizi kakhulu kunye neenkqubo ezifakiweyo.

I-antenna yokuphakelwa, edla ngokubizwa ngokuba "yi-feed," yinxalenye ephambili kwinkqubo ye-antenna yokuphakelwa ekhupha amandla e-electromagnetic ukuya kwi-reflector ephambili okanye iqokelela amandla kuyo. Yona ngokwayo yi-antenna epheleleyo (umz., i-antenna ye-horn), kodwa ukusebenza kwayo kumisela ngokuthe ngqo ukusebenza kakuhle kwenkqubo ye-antenna iyonke.

Umsebenzi wayo oyintloko kukukhanyisa ngempumelelo i-reflector ephambili. Eyona nto ifanelekileyo kukuba, ipateni yemitha ye-feed kufuneka igubungele ngokuchanekileyo wonke umphezulu we-reflector ngaphandle kokuchitheka ukuze kufumaneke inzuzo ephezulu kunye ne-side lobes ephantsi. Iziko le-phase ye-feed kufuneka libekwe ngokuchanekileyo kwindawo ephambili ye-reflector.

Inzuzo ephambili yale nxalenye yindima yayo njenge "sango" lokutshintshiselana kwamandla; uyilo lwayo luchaphazela ngokuthe ngqo ukusebenza kakuhle kokukhanya kwenkqubo, amanqanaba e-cross-polarization, kunye nokuhambelana kwe-impedance. Ingxaki yayo ephambili kuyilo lwayo oluntsonkothileyo, olufuna ukufana ngokuchanekileyo ne-reflector. Isetyenziswa kakhulu kwiinkqubo ze-antenna ze-reflector ezifana nonxibelelwano lwesathelayithi, iiteleskopu zerediyo, i-radar, kunye neekhonkco ze-microwave relay.
