I-antenna yophondo ingenye yezimpondo ezisetshenziswa kakhulu ezinesakhiwo esilula, ububanzi befrikhwensi ebanzi, umthamo wamandla amakhulu kanye nokuzuza okuphezulu.Izimpondo zophondozivame ukusetshenziswa njengezinti eziphakelayo kusayensi yezinkanyezi yomsakazo wezinga elikhulu, ukulandelela ngesathelayithi, nezimpondo zokuxhumana.Ngokungeziwe ekusebenzeni njengokuphakelayo kwezibonisi namalensi, iyinto evamile kumalungu afanayo anezigaba futhi isebenza njengezinga elivamile lokulinganisa nokuzuza izilinganiso zamanye ama-antenna.
I-antenna yophondo yakhiwa ngokuvula kancane kancane i-waveguide engunxande noma i-waveguide eyindilinga ngendlela ethile.Ngenxa yokwanda kancane kancane komlomo we-waveguide, ukufanisa phakathi kwe-waveguide nesikhala esikhululekile kuyathuthukiswa, okwenza i-coefficient yokubonisa ibe mncane.Ku-waveguide ephakelwayo engunxande, ukudluliswa kwemodi eyodwa kufanele kufinyelelwe ngangokunokwenzeka, okungukuthi, amagagasi e-TE10 kuphela adluliswayo.Lokhu akugxili kuphela amandla esignali futhi kunciphisa ukulahlekelwa, kodwa futhi kugwema umthelela wokuphazanyiswa kwemodi ephakathi kanye nokuhlakazeka okwengeziwe okubangelwa izindlela eziningi..
Ngokwezindlela ezihlukene zokuthunyelwa kwezimpondo zezimpondo, zingahlukaniswa zibeizimpondo zezimpondo, izimpondo zephiramidi,ama-antenna ophondo oluyi-conical, izimpondo zikathayela, izimpondo zezimpondo ezimangelengele, izimpondo zezimpondo zemodi eminingi, njll. Lezi zimpondo ezivamile zichazwe ngezansi.Isingeniso ngamunye ngamunye
I-antenna yophondo lomkhakha
I-e-plane yophondo lwe-antenna
I-antenna yophondo lwe-E-plane yenziwe nge-waveguide engunxande evulwe nge-engeli ethile lapho ibheke endaweni kagesi.
Isibalo esingezansi sibonisa imiphumela yokulingisa ye-antenna yophondo lwe-E-plane.Kuyabonakala ukuthi ububanzi be-beam yaleli phethini ekuqondeni kwe-E-plane buncane kunendlela yendiza ye-H, okubangelwa indawo enkulu yokuvula i-E-plane.
I-antenna yophondo lwe-H-plane
I-antenna yophondo lwe-H-plane yenziwe nge-waveguide engunxande evulwe nge-engeli ethile ibheke endaweni kazibuthe.
Isibalo esingezansi sibonisa imiphumela yokulingisa ye-antenna yophondo lomkhakha we-H-plane.Kuyabonakala ukuthi ububanzi be-beam yaleli phethini ekuqondeni kwendiza ye-H buncane kunesiqondiso se-E-plane, okubangelwa ukuvuleka okukhulu kwendiza ye-H.

Iphiramidi yophondo lwe-antenna yenziwe nge-waveguide engunxande evulwa nge-engeli ethile ezinhlangothini ezimbili ngesikhathi esisodwa.
Isibalo esingezansi sibonisa imiphumela yokulingisa ye-antenna yophondo lwe-pyramidal.Izici zayo zemisebe ngokuyisisekelo ziyinhlanganisela yezimpondo zomkhakha we-E-plane kanye ne-H-plane.
I-antenna yophondo oluyi-Conical
Uma isiphetho esivulekile se-waveguide esiyindilinga simise okophondo, sibizwa ngokuthi i-conical horn antenna.I-antenna yophondo lwe-cone inombobo oyindilinga noma oyi-elliptical ngaphezu kwayo.
Isibalo esingezansi sibonisa imiphumela yokulingisa ye-antenna yophondo oluyi-conical.
Imikhiqizo ye-antenna ye-conical ye-RFMISO:
RM-CDPHA218-15
I-RM-CDPHA618-17
I-antenna yophondo lukathayela
I-antenna yophondo lukathayela iyi-antenna enophondo olunothayela lwangaphakathi.Inezinzuzo ze-wide frequency band, i-cross-polarization ephansi, nokusebenza okuhle kwe-beam symmetry, kodwa ukwakheka kwayo kuyinkimbinkimbi, nobunzima bokucubungula kanye nezindleko ziphezulu.
Izimpondo zophondo lukathayela zingahlukaniswa zibe izinhlobo ezimbili: izimpondo zikathayela eziyiphiramidi kanye nezimpondo zikathayela eziwugwadule.
Imikhiqizo yezimpondo zikathayela we-RFMISO:
RM-CHA140220-22
I-Pyramidal corrugated antenna yophondo
I-antenna yophondo lukathayela oluqinile
Isibalo esingezansi sibonisa imiphumela yokulingisa yophondo lukathayela oluyikhonikhali.
I-antenna yophondo olugobile
Uma imvamisa yokusebenza ye-antenna evamile yophondo ingaphezu kuka-15 GHz, i-lobe yangemuva iqala ukuhlukana futhi izinga le-lobe eseceleni liyakhuphuka.Ukwengeza ukwakheka kwe-ridge ku-cavity yesipika kungakhuphula umkhawulokudonsa, kunciphise i-impedance, kukhuphule inzuzo, futhi kuthuthukise ukuqondiswa kwemisebe.
Izimpondo ezinezimpondo ezinezimpondo ezine ezinde.Okulandelayo kusebenzisa i-antenna yophondo oluphindwe kabili oluyi-pyramidal njengesibonelo sokulingisa.
IPyramid Double Ridge Horn Antenna
Ukwengeza izakhiwo ezimbili zamagquma phakathi kwengxenye ye-waveguide kanye nengxenye yokuvula uphondo kuwuthi lwephondo olunemigqa emibili.Ingxenye ye-waveguide ihlukaniswe yaba imbobo engemuva kanye ne-ridge waveguide.I-cavity engemuva ingahlunga amamodi e-oda eliphezulu ajabulile ku-waveguide.I-ridge waveguide inciphisa imvamisa yokunqamuka kokudluliswa kwemodi eyinhloko, ngaleyo ndlela ifeze injongo yokwandisa ibhendi yefrikhwensi.
I-antenna yophondo olugobile incane kune-antenna yophondo olujwayelekile kubhendi yefrikhwensi efanayo futhi inenzuzo ephezulu kune-antenna evamile yophondo kubhendi efanayo yefrikhwensi.
Isibalo esingezansi sibonisa imiphumela yokulingisa yophondo lwe-pyramidal oluphindwe kabili lwe-antenna.
I-antenna yophondo lwe-Multimode
Ezinhlelweni eziningi, izimpondo zophondo ziyadingeka ukuze zinikeze amaphethini alinganayo kuzo zonke izindiza, ukuqondana kwesikhungo sesigaba ezindizeni ze-$E$ ne-$H$, kanye nokucindezelwa kwe-lobe eseceleni.
Isakhiwo sophondo esivusa amadlingozi esinemodi eminingi singathuthukisa umphumela wokulinganisa we-beam wendiza ngayinye futhi sinciphise izinga le-lobe eseceleni.Olunye lwezimpondo ze-multimode ezivame kakhulu uphondo lwe-conical olunemodi emibili.
I-Dual Mode I-Conical Horn Antenna
Uphondo lwekhoni yemodi ekabili luthuthukisa iphethini yendiza engu-$E$ ngokwethula imodi ye-TM11 yemodi yokuhleleka okuphezulu, ukuze iphethini yayo ibe nezici ze-axially ezilingana ngokulinganayo.Isibalo esingezansi siwumdwebo wohlelo lokusatshalaliswa kwensimu kagesi yokuvula yemodi eyinhloko ye-TE11 kanye nemodi yokuhleleka okuphezulu kwe-TM11 ku-waveguide eyindilinga kanye nokusabalalisa kwensimu yokuvula okuhlanganisiwe.
Ifomu lokuqaliswa kwesakhiwo sophondo oluyimodi ekabili alihlukile.Izindlela zokusetshenziswa ezijwayelekile zifaka uphondo lwe-Potter kanye nophondo lwe-Pickett-Potter.
Isibalo esingezansi sibonisa imiphumela yokulingisa ye-antenna yophondo lwePotter enemodi ekabili.
