I-antenna yephondokwayei-antenna ephindwe kabini epholisiweyoziintlobo ezimbini zee-antenna ezisetyenziswa kwiindawo ezahlukeneyo ngenxa yeempawu zazo ezizodwa kunye nemisebenzi yazo. Kweli nqaku, siza kuphonononga iimpawu zee-antenna ze-horn kunye nee-antenna ezi-dual-polarized size sihlolisise usetyenziso olwahlukeneyo apho ezi antenna zisetyenziswa khona rhoqo.
I-antenna yeHorn yi-antenna ebhekisa kwicala elisetyenziswa kakhulu kwiinkqubo zonxibelelwano lwe-microwave kunye nerediyo. Zibonakaliswa ngesimo se-conical okanye se-pyramidal, esivumela ukuba zikhuphe kwaye zifumane amaza e-electromagnetic ngokufanelekileyo. Ii-antenna zeHorn zenzelwe ukuba zibe ne-bandwidth ebanzi kunye ne-high gain, nto leyo eyenza ukuba zilungele unxibelelwano olude kunye neenkqubo ze-radar.
Kwelinye icala, i-antenna ene-dual-polarized yi-antenna enokuhambisa kwaye ifumane amaza erediyo kwii-orthogonal polarizations ezimbini ngaxeshanye. Oku kuthetha ukuba zinokusingatha zombini i-polarization ethe tye nethe nkqo, ngaloo ndlela zonyusa umthamo wedatha kunye nomgangatho wesignali kwiinkqubo zonxibelelwano.
Enye yezona ndawo ziphambili ezisetyenziswayo kwii-antenna ze-horn ziinkqubo ze-radar. Ngenxa yeempawu zazo eziphezulu zokufumana kunye nokuqondisa, ii-antenna ze-horn zihlala zisetyenziswa kwi-radar zokulawula i-air traffic, ukujonga imozulu, kunye nokujonga umkhosi. Ukukwazi kwazo ukuhambisa ngokuchanekileyo kunye nokufumana amaza e-electromagnetic kumgama omde kuzenza zibe yinxalenye ebalulekileyo yetekhnoloji ye-radar.
Ukongeza kwiinkqubo zeradar, ii-antenna ze-horn zikwasetyenziswa kunxibelelwano lwesathelayithi. I-bandwidth ebanzi kunye nokwanda okukhulu kwee-antenna ze-horn kuzenza zilungele ukudlulisa nokufumana imiqondiso evela kwi-satellites esibhakabhakeni. Nokuba kukusasazwa kumabonwakude, uqhagamshelo lwe-intanethi okanye iinkqubo zokubeka indawo kwihlabathi liphela, ii-antenna ze-horn zidlala indima ebalulekileyo ekusekeni amakhonkco onxibelelwano anokuthenjwa neesathelayithi.
Ngaphezu koko, ii-antenna ze-horn zisetyenziswa kakhulu kwiinkqubo zonxibelelwano ezingenazingcingo ezifana nee-microwave links ezikwi-point-to-point kunye nee-wireless local area networks (WLANs). Ulawulo lwazo kunye nokuzuza kwazo okuphezulu kuzenza zilungele ukuseka uqhagamshelo olungenazingcingo olukude, ingakumbi kwiindawo zasezidolophini nezasemaphandleni apho unxibelelwano oluhambelana nomgca lubaluleke kakhulu.
I-RFMISOIingcebiso zothotho lweemveliso ze-antenna zephondo:
RM-SGHA430-15（1.70-2.60GHz）
I-RM-BDHA618-10 (6-18GHz)
RM-CDPHA3337-20 (33-37GHz)
Ngokoii-antenna ezi-double-polarized, zihlala zisetyenziswa kwiinkqubo zonxibelelwano ezingenazingcingo ezifuna i-data throughput ephezulu kunye nokuthembeka kwesignali. Umzekelo, kwiinethiwekhi zeselula, ii-antennas ezine-dual-polarized zisetyenziselwa ukuphucula amandla kunye nokusebenza kwezikhululo zesiseko ngokuxhasa i-multi-input multiple-output.iteknoloji (MIMO)Ngokuthumela nokufumana imiqondiso kwii-polarizations ezimbini ze-orthogonal, ii-antennas ezine-dual-polarized zinokutshintshiselana ngedatha ngaxeshanye, ziphucula ukusebenza kakuhle kwe-spectral kunye nokugubungela inethiwekhi.
Ukongeza, ii-antenna ezi-dual-polarized zizinto ezibalulekileyo kwi-radio astronomy nakwizicelo zokuva kude. Ziyakwazi ukubamba amaza erediyo a-polarized ngokuthe tye nangokuthe nkqo, okuvumela ukubonwa ngokuchanekileyo kunye nohlalutyo lweziganeko zezulu kunye nezendalo. Kwi-radio astronomy, ii-antenna ezi-dual-polarized zisetyenziselwa ukufunda iimpawu ze-polarization zemithombo yezulu, zibonelela ngengqiqo ebalulekileyo malunga nohlobo lwezidalwa zezulu kunye nendalo yonke.
Kwicandelo losasazo olungenazingcingo, ii-antenna ezine-polarized ezimbini zisetyenziselwa ukusasazwa kwethelevishini yomhlaba kunye nerediyo. Ngokusebenzisa ii-antenna ezine-polarized ezimbini, abasasazi banokuphucula ukusetyenziswa kwe-radio spectrum kwaye baphucule umgangatho wemiqondiso yosasazo, ukuqinisekisa amava angcono okuvakalayo nokubonakalayo kubabukeli.
