I-Antenna ye-Vivaldi: Isimiso Sokusebenza, Izici kanye Nezicelo

I-antenna ye-Vivaldi, eyaziwa nangokuthi i-antenna yesikhala esinciphile, iyi-antenna eqondisa i-broadband esetshenziswa kabanzi ku-RF, kuma-microwave, kuma-radar, kuma-electronic warfare, kuma-measurement, kanye nasezinhlelweni zokuhlola ezingenantambo. Ukuvulwa kwayo okunciphile okuhlukile kuvumela amandla kagesi ukuthi ashintshe kancane kancane esuka esakhiweni sokudlulisa esiqondisiwe aye endaweni ekhululekile, okusiza i-antenna ukuthi ifinyelele ukusebenza kwe-broadband kanye nemisebe eqondisa isiqondiso.

Uma kuqhathaniswa nama-antenna amaningi azwakalayo alungiselelwe eduze kwebhendi yemvamisa emincane, ama-antenna e-Vivaldi asebenzisa isakhiwo samagagasi ahambayo. Lokhu kuwenza akhanga kakhulu izinhlelo ezidinga ukumbozwa kwemvamisa ebanzi kanye nokucushwa okulula kwe-planar noma kwe-mechanical.

Isebenza Kanjani I-Antenna ye-Vivaldi?

I-antenna eyisisekelo ye-Vivaldi iqukethe imiphetho emibili eqhubayo eyakha i-slot enciphile. I-slot ikhula kancane kancane isuka endaweni encane yokudla iye endaweni ebanzi evulekayo.

Uma amandla e-RF engena ku-antenna, igagasi likagesi lihamba ngesikhala esinciphile. Njengoba ububanzi besikhala bukhula, igagasi eliqondiswayo liyaqhubeka nokuhlangana endaweni ekhululekile futhi likhanya ngokuyinhloko ngasekugcineni kwe-antenna.

Lokhu kushintsha kancane kancane kungenye yezizathu ezibalulekile ezenza ama-antenna e-Vivaldi anikeze izici ze-broadband.

Imvamisa ephansi esebenzisekayo ithonywa kakhulu usayizi obonakalayo we-aperture kanye ne-taper, kuyilapho ukusebenza kwemvamisa ephezulu kuncike kakhulu ezintweni ezifana nokushintsha kokudla, i-geometry ye-taper, ubukhulu bomqhubi, kanye nokunemba kokukhiqiza.

Izici Zokushiswa Kwemisebe

I-antenna yeVivaldi ngokuvamile iyi-antenna yomlilo, okusho ukuthi imisebe yayo eyinhloko iqondiswe ekugcineni okuvulekile kwe-aperture enciphile.

Izici zayo zokukhanya zincike kumingcele eminingana yokuklama, okuhlanganisa:

Ububanzi bembobo
Ubude be-Taper kanye nephrofayili
Isakhiwo sokuphakelayo
Imvamisa yokusebenza
I-geometry yomhlabathi kanye nomqhubi
Ubukhulu bemishini

Njengoba imvamisa ishintsha, indawo ekhipha imisebe esebenza kahle esakhiweni esinciphile nayo iyashintsha. Lokhu kuvumela i-antenna ukuthi isebenze kububanzi bemvamisa ebanzi ngaphandle kokuthembela ekukhanyeni okukodwa okunciphile.

Ama-antenna e-Vivaldi avame ukuklanywa ukuze kube nokuhlukaniswa okuqondile, yize ukusebenza kokuhlukaniswa kuncike ku-geometry ethile kanye nokuhlelwa kokudla.

Izinhlobo Eziyinhloko Zama-Antenna e-Vivaldi

Ukucushwa okuningana kwe-antenna ye-Vivaldi kuvame ukusetshenziswa kubunjiniyela be-RF.

I-Antenna ye-Vivaldi evamile
Isebenzisa isikhala esinciphile esakhiwe phakathi kwezifunda ezimbili eziqhuba ugesi futhi ingenye yezindlela ezivame kakhulu zokusebenzisa.

I-Antenna ye-Antipodal Vivaldi
Isebenzisa izakhi eziqhuba ugesi ezinhlangothini eziphambene ze-substrate ye-dielectric. Lokhu kulungiselelwa kunganikeza ukuguquka okulula kusuka kokuphakelwa komugqa wokudlulisela okuthile kuya ku-aperture ekhipha imisebe.

I-Antenna ye-Antipodal Vivaldi elinganiselayo
Isebenzisa isakhiwo esinezingqimba eziningi ezilinganayo ukuze ithuthukise ibhalansi yensimu kanye nezici zokuhlukanisa kwezinye izinhlelo zokusebenza ze-broadband.

Ukucushwa okuhlukene kungakhethwa ngokuya nge-bandwidth, i-polarization, indlela yokuphakelayo, inqubo yokukhiqiza, kanye nezidingo zokuhlanganiswa kwesistimu.

Amapharamitha Ayisihluthulelo Uma Ukhetha I-Antenna ye-Vivaldi

Uma ukhetha i-antenna yeVivaldi, ububanzi bemvamisa buyisiqalo nje.

I-Gain ikhombisa ukuthi i-antenna igxila kanjani imisebe ngendlela ephumelela kakhulu phambili.

I-VSWR ibonisa ukufana kwe-impedance phakathi kwe-antenna kanye nesistimu ye-RF. I-VSWR ephansi ngokuvamile isho amandla angabonakali kakhulu.

I-Polarization kufanele ifane nesistimu ye-RF eqondiwe ukuze kuncishiswe ukungalingani kwe-polarization.

I-3 dB Beamwidth ichaza ububanzi be-angular bomsebe oyinhloko wemisebe futhi ibalulekile ekusetshenzisweni kwe-radar, ukuqapha, kanye nokulinganisa okuqondisiwe.

Ukusebenza kwe-Cross-Polarization kubalulekile futhi lapho ubumsulwa be-polarization bubalulekile.

Izici zemishini ezifana nohlobo lwesixhumi, ubukhulu be-antenna, isisindo, isakhiwo sokufaka, kanye nokuphathwa kwamandla kufanele futhi kucatshangelwe ngesikhathi sokuhlanganiswa kwesistimu.

Isibonelo, i-RF MISO's RM-VA0212-6 Linear Polarized Vivaldi Antenna isebenza kusukela ku-0.2 kuya ku-1.2 GHz, inikeza inzuzo ejwayelekile engu-6 dBi, isebenzisa i-linear polarization kanye ne-interface ye-N-Female, futhi ichazwe kuma-radar, ukuxhumana kwesathelayithi, i-electronic warfare, kanye nezinhlelo zokusebenza zokuhlola ezingenantambo eziphezulu.

Izinzuzo ze-Vivaldi Antennas

Ama-antenna e-Vivaldi anikeza izinzuzo eziningana ezisebenzayo:

Ububanzi bokusebenza
Imisebe yomlilo oqondile
Isakhiwo esikhanyayo esilula kakhulu
Ukuhambisana okuhle nezinhlelo ze-RF ze-broadband
Idizayini ekhula ngokushesha kuzo zonke izinhlobo zemvamisa ezahlukene
Ifanele ukucushwa kwe-single-element kanye ne-array

Izici zabo ze-broadband zibenza babe usizo kakhulu lapho uhlelo ludinga ukumboza amaza amaningi ngaphandle kokushintsha ama-antenna njalo.

Izicelo

Ama-antenna e-Vivaldi avame ukusetshenziswa ku:

Izinhlelo ze-radar
Impi ye-elekthronikhi
Ukulinganiswa kwe-RF ye-Broadband
Ukuhlolwa okungenantambo
Ukuthola isiqondiso
Ukuqapha isignali
Izithombe ze-microwave
Izinhlelo zokuxhumana
Ama-antenna ahleliwe
Ucwaningo kanye nezicelo zelebhu

Ezinhlelweni ze-array, izakhi eziningi ze-Vivaldi zingahlelwa futhi ukuze kutholakale inzuzo ephezulu, imisebe emincane, noma ikhono lokulawula imisebe kagesi.

Isiphetho

I-antenna yeVivaldi ihlanganisa isakhiwo se-traveling-wave esinciphile, ukusebenza kwe-broadband, kanye nemisebe eqondisa isiqondiso, okwenza kube ukwakheka kwe-antenna okuguquguqukayo kwezinhlelo ze-RF zesimanje kanye ne-microwave.

Ukusebenza kwayo kwangempela kuncike ku-geometry ye-taper, usayizi we-aperture, ukwakheka kokudla, imvamisa yokusebenza, kanye nokusetshenziswa kwemishini. Ngakho-ke onjiniyela akufanele bahlole i-bandwidth kanye ne-gain kuphela, kodwa futhi ne-VSWR, i-polarization, i-beamwidth, ukusebenza kwe-cross-polarization, i-RF interface, kanye nezidingo zokufaka lapho bekhetha imodeli efanelekile.

Ngezinhlelo zokusebenza ze-radar, i-electronic warfare, ukulinganisa i-broadband, ukuxhumana, kanye nokuhlola okungenantambo, ama-antenna e-Vivaldi ahlinzeka ngesisombululo esiguquguqukayo lapho ukumbozwa kwemvamisa ebanzi kanye nokusebenza kwe-RF okuqondisiwe kubalulekile kokubili.
