I-Antenna yeVivaldi: Umgaqo wokusebenza, iimpawu kunye nokusetyenziswa

I-antenna yeVivaldi, ekwaziwa ngokuba yi-antenna ye-slot e-tapered, yi-antenna e-broadband directional esetyenziswa kakhulu kwi-RF, kwi-microwave, kwi-radar, kwi-electronic warfare, kwiinkqubo zokulinganisa, nakwiinkqubo zovavanyo ezingenazingcingo. I-aperture yayo eyahlukileyo e-tapered ivumela amandla e-electromagnetic ukuba atshintshe kancinci ukusuka kwisakhiwo sothumelo olukhokelwayo ukuya kwindawo ekhululekileyo, enceda i-antenna ukuba ifezekise ukusebenza kwe-broadband kunye ne-radiation directional.

Xa kuthelekiswa nee-antenna ezininzi ezivakalayo ezilungiselelwe ukujikeleza ibhendi yefrikhwensi encinci, ii-antenna zeVivaldi zisebenzisa isakhiwo se-traveling-wave. Oku kuzenza zibe nomtsalane ngakumbi kwiinkqubo ezifuna ukugubungela ifrikhwensi ebanzi kunye nolwakhiwo olulula lwe-planar okanye lwe-metallic mechanical.

Isebenza njani i-Antenna yeVivaldi?

I-antenna esisiseko yeVivaldi inemiphetho emibini eqhubayo eyenza isithuba esinciphileyo. Isithuba siyanda kancinci kancinci ukusuka kwindawo encinci yokutya ukuya kwindawo ebanzi ekhupha imitha.

Xa amandla e-RF engena kwi-antenna, i-electromagnetic wave ihamba kwindawo ethe tyaba. Njengoko ububanzi be-slot bukhula, i-guided wave iyaqhubeka nokudibana kwindawo ekhululekileyo kwaye isasazeka ikakhulu ngasekuphumeni kwe-antenna.

Olu tshintsho luhamba kancinci kancinci yenye yezizathu eziphambili zokuba ii-antenna zeVivaldi zinokubonelela ngeempawu ze-broadband.

Ubuninzi obusebenzisekayo obuphantsi buchatshazelwa kakhulu bubungakanani bomngxuma kunye ne-taper, ngelixa ukusebenza kwamaza aphezulu kuxhomekeke kakhulu kwizinto ezifana notshintsho lwe-feed, i-taper geometry, ubukhulu bomqhubi, kunye nokuchaneka kokwenziwa.

Iimpawu zeMisebe

I-antenna yeVivaldi ngokuqhelekileyo yi-antenna yomlilo, oko kuthetha ukuba imitha yayo ephambili ijoliswe kwisiphelo esivulekileyo se-aperture enciphileyo.

Iimpawu zayo zemitha zixhomekeke kwiiparameter ezininzi zoyilo, kuquka:

Ububanzi bembobo
Ubude beTaper kunye neprofayili
Isakhiwo sesondlo
Isantya sokusebenza
Ijometri yomhlaba kunye nomqhubi
Ubukhulu boomatshini

Njengoko i-frequency itshintsha, ummandla osebenzayo wokurhawuzelela kwisakhiwo esinciphileyo nawo uyatshintsha. Oku kuvumela i-antenna ukuba isebenze kuluhlu olubanzi lwe-frequency ngaphandle kokuxhomekeka kwi-resonance enye encinci.

Ii-antenna zeVivaldi zihlala zenzelwe i-linear polarization, nangona ukusebenza kwe-polarization kuxhomekeke kwi-geometry ethile kunye nolungiselelo lokutya.

Iiparameters eziphambili xa ukhetha i-Vivaldi Antenna

Xa ukhetha i-antenna yeVivaldi, uluhlu lweefrikhwensi yindawo yokuqala kuphela.

I-Gain ibonisa indlela i-antenna egxila ngayo imitha kwicala eliya phambili.

I-VSWR ibonisa ukuhambelana kwe-impedance phakathi kwe-antenna kunye nenkqubo ye-RF. I-VSWR esezantsi ngokubanzi ithetha amandla angaboniswanga kakhulu.

I-Polarization kufuneka ihambelane nenkqubo ye-RF ekujoliswe kuyo ukuze kuncitshiswe ukungalingani kwe-polarization.

I-3 dB Beamwidth ichaza ububanzi be-angular bomsebe ophambili wemitha kwaye ibalulekile kwi-radar, esweni, nakwizicelo zokulinganisa kwicala.

Ukusebenza kwe-Cross-Polarization kubalulekile xa ubumsulwa be-polarization bubalulekile.

Izinto ezisetyenziswa ngoomatshini ezifana nohlobo lwesixhumi, ubukhulu be-antenna, ubunzima, ulwakhiwo lokufakela, kunye nokuphathwa kwamandla nazo kufuneka ziqwalaselwe ngexesha lokuhlanganiswa kwenkqubo.

Umzekelo, i-RF MISO's RM-VA0212-6 Linear Polarized Vivaldi Antenna isebenza ukusuka kwi-0.2 ukuya kwi-1.2 GHz, ibonelela nge-6 dBi typical gain, isebenzisa i-linear polarization kunye ne-N-Female interface, kwaye ichazwe kwi-radar, unxibelelwano lwesathelayithi, i-electronic warfare, kunye nezicelo zovavanyo lwe-wireless eziphezulu.
