I-eriyali yophondokwayei-eriyali epholisiweyo kabiniziindidi ezimbini zee-eriyali ezisetyenziswa kwiindawo ezahlukeneyo ngenxa yeempawu zazo ezizodwa kunye nemisebenzi. Kweli nqaku, siza kuphonononga iimpawu zee-eriyali zeempondo kunye nee-eriyali ezinepolarized ezimbini kwaye sijonge kwizinto ezahlukeneyo ezisetyenziswa kuzo ezi eriyali.
I-eriyali ye-Horn yi-eriyali eyalathayo esetyenziswa ngokubanzi kwiinkqubo ze-microwave kunye nerediyo zonxibelelwano. Zibonakaliswe yi-conical okanye i-pyramidal shape, evumela ukuba baphume ngokufanelekileyo kwaye bafumane amaza e-electromagnetic. Iimpondo zeempondo zenzelwe ukuba zibe ne-bandwidth ebanzi kunye nokuzuza okuphezulu, okwenza ukuba zilungele unxibelelwano olude kunye neenkqubo ze-radar.
I-eriyali ene-polarized kabini, kwelinye icala, yi-eriyali enokusasaza kwaye ifumane amaza erediyo kwiipolarizations ezimbini ze-orthogonal ngaxeshanye. Oku kuthetha ukuba banokusingatha i-polarization ethe tye kunye nethe nkqo, ngaloo ndlela benyusa umthamo wedatha kunye nomgangatho wophawu kwiinkqubo zonxibelelwano.
Enye yeendawo eziphambili zokusetyenziswa kwee-eriyali zephondo ziinkqubo ze-radar. Ngenxa yenzuzo ephezulu kunye neempawu zokuqondisa, ii-eriyali zeempondo ziqhele ukusetyenziswa kufakelo lwe-radar kulawulo lwezithuthi zomoya, ukujonga imozulu, kunye nokucupha emkhosini. Ukukwazi kwabo ukusasaza ngokuchanekileyo kunye nokufumana amaza e-electromagnetic kumgama omde kubenza babe yinxalenye ebalulekileyo yetekhnoloji yeradar.
Ukongeza kwiinkqubo ze-radar, ii-eriyali zeempondo zikwasetyenziswa kunxibelelwano lwesathelayithi. I-bandwidth ebanzi kunye nokuzuza okuphezulu kwee-antenna zephondo kubenza bafaneleke ukuhambisa kunye nokufumana izibonakaliso kwiisathelayithi ezisesithubeni. Nokuba lusasazo lukamabonakude, uqhagamshelo lwe-intanethi okanye iinkqubo zokumisa umhlaba jikelele, iimpondo zempondo zidlala indima ebalulekileyo ekusekeni amakhonkco onxibelelwano athembekileyo neesathelayithi.
Ngaphaya koko, ii-eriyali zeempondo zisetyenziswa ngokubanzi kwiinkqubo zonxibelelwano ezingenazingcingo ezifana ne-point-to-point microwave links kunye nee-wireless area networks (WLANs). Ukhokelo lwabo oluthe ngqo kunye nokuzuza kwabo okuphezulu kubenza balungele ukuseka imidibaniso yamacingo ahamba umgama omde, ngakumbi kwiindawo zasezidolophini nasezilalini apho unxibelelwano lwe-line-of-sight lubaluleke kakhulu.
RFMISOIingcebiso zothotho lweMveliso ye-Antenna:
RM-SGHA430-15 (1.70-2.60GHz)
RM-BDHA618-10(6-18GHz)
RM-CDPHA3337-20 (33-37GHz)
Ngokoii-eriyali ezimbini-polarized, zidla ngokusetyenziswa kwiinkqubo zonxibelelwano ezingenazintambo ezifuna ukuhanjiswa kwedatha ephezulu kunye nokuthembeka komqondiso. Ngokomzekelo, kwiinethiwekhi zeselula, ii-antenna ezi-dual-polarized zisetyenziselwa ukunyusa umthamo kunye nokusebenza kwezikhululo ezisisiseko ngokuxhasa i-multiple-input-output-output.(MIMO) iteknoloji. Ngokuthumela kunye nokufumana izibonakaliso kwiipolarizations ezimbini ze-orthogonal, i-antenna ezimbini-polarized zinokutshintshiselana ngedatha ngaxeshanye, ukuphucula ukusebenza kakuhle kwe-spectral kunye nokugubungela inethiwekhi.
Ukongeza, ii-eriyali ezi-polarized ezimbini zizinto eziyimfuneko kwiastronomy yerediyo kunye nezixhobo zokuvalela kude. Bayakwazi ukubamba amaza kanomathotholo ngokuthe tye nathe nkqo, evumela ukubonwa okuchanekileyo kunye nohlalutyo lweziganeko zezulu kunye nokusingqongileyo. Kwi-astronomy kanomathotholo, ii-eriyali ezinepolarized zisetyenziselwa ukufunda iipropathi zepolarization zemithombo yecosmic, zibonelela ngolwazi oluxabisekileyo ngobume bendalo esezulwini kunye nendalo iphela.
Kwintsimi yosasazo olungenazingcingo, ii-eriyali eziphindwe kabini zisetyenziselwa usasazo lukamabonakude olusemhlabeni kunye nonomathotholo. Ngokusebenzisa ii-eriyali ezi-polarized ezimbini, abasasazi banokwandisa ukusetyenziswa kwe-spectrum yerediyo kunye nokuphucula umgangatho wemiqondiso yosasazo, beqinisekisa amava angcono okubukwayo kubabukeli.
