I-Antenna yeBiconical: Umgaqo wokusebenza, uyilo kunye nosetyenziso

A i-antenna ye-biconicalyi-antenna ye-broadband eyenziwe ziikhowuni ezimbini eziqhubayo ezibekwe kwincam ukuya kwincam kwaye zondliwa kwiincopho zazo. I-geometry yayo etshintsha kancinci inika i-bandwidth ebanzi yokusebenza kune-dipole eqhelekileyo yentambo encinci, okwenza ukuba ibe luncedo ekulinganisweni kwe-wideband, uvavanyo lokuhambelana kwe-electromagnetic, ukujonga i-spectrum, unxibelelwano kunye nokusetyenziswa kwe-radar.

Yintoni i-Antenna yeBiconical?

I-antenna ye-biconical inokujongwa njenge-dipole ye-broadband enemilinganiselo emithathu. Iikhowuni ezimbini ezichaseneyo zisebenza njengezinto ezikhupha imitha, ngelixa i-feed ikwisithuba esincinci phakathi kweencopho zazo. I-angle yekhowuni, ubude bekhowuni, i-geometry ye-feed kunye nesakhiwo esijikelezileyo zimisela uluhlu lwefrikhwensi olusebenzisekayo, ukufana kwe-impedance kunye neempawu zemitha.

Ngokuxhomekeke kubukhulu bayo kunye nofakelo lwayo, i-antenna inokubonelela nge-linear polarization kunye nephethini ye-azimuth ejikelezayo ngokubanzi. Ukusebenza kuyatshintsha kulo lonke ibhendi yokusebenza, ngoko ke i-gain echaziweyo, i-VSWR kunye nephethini yemitha kufuneka ihlale ijongwa kuluhlu lwefrikhwensi olucetywayo.

Isebenza Njani I-Antena YeeBiconical?

Umsinga we-RF ungena kwi-antenna kwindawo yokutya uze uhambe kwiindawo ezikhupha umoya ezikhulayo. Ngenxa yokuba umqhubi uyanda kancinci kancinci, utshintsho oluvela kwindawo yokutya ukuya kwindawo ekhululekileyo luhamba kakuhle kuluhlu olubanzi lweefrikhwensi. Le geometry inceda ukugcina i-input impedance esebenzisekayo kunye nemitha ezinzileyo kububanzi bebhendi kune-narrowband dipole.

I-antenna ayixhomekekanga kwi-multipath reflections ngaphakathi kweekhowuni. I-radiation iveliswa yi-currents etshintsha-tshintsha ngexesha kwiindawo eziqhuba umbane. Kwii-frequency eziphezulu, ubungakanani bombane kunye neenkcukacha ze-feed zinokwenza utshintsho olongezelelweyo lwepateni, yiyo loo nto uyilo lwe-broadband kufuneka luvavanywe kuyo yonke ibhendi yokusebenza.

IiParamitha zoYilo oluPhambili

• Uluhlu lwefrikhwensi:Ibhendi epheleleyo apho kuhlangatyezwana neemfuno ze-impedance kunye ne-radiation.
• I-VSWR kunye ne-impedance:Ezi zibonisa indlela amandla e-RF adluliselwa ngayo ngokufanelekileyo phakathi komgca wesondlo kunye ne-antenna.
• Inzuzo:Ii-antenna ze-broadband biconical zihlala zibonelela ngenzuzo ephakathi eyahluka rhoqo.
• Ipatheni yokukhanya:Uzinzo lweepateni kunye nokugquma kwe-azimuth kufuneka kujongwe kulo lonke ibhendi.
• Ukwahlulwahlulwa:Ulwalathiso lumisela icala le-linear polarization.
• Isixhumi kunye nokuphathwa kwamandla:Zombini mazihambelane nenkqubo yovavanyo okanye umthombo weRF.
• Ubungakanani boomatshini:Ubukhulu bekhowuni buchaphazela isantya esiphantsi esisebenzisekayo kunye neemfuno zokufakela.

Izicelo Eziqhelekileyo

• Ukulinganiswa kokukhutshwa kwemitha ye-EMC kunye nokukhuselwa komzimba
• Uvavanyo lwe-antenna ebanzi kunye nenkqubo ye-RF
• Ukubeka iliso kwi-spectrum kunye nokuqokelelwa kwesignali
• Uvavanyo lonxibelelwano olungenazingcingo kunye neradar
• Iinkqubo zokulinganisa ilabhoratri kunye nokulinganisa intsimi

Iingenelo kunye nokunqongophala

Ii-antenna zeBiconical zibonelela nge-bandwidth ebanzi, ulwakhiwo olulula kunye nokugubungela ipateni eluncedo. Zinganciphisa isidingo sokutshintsha ii-antenna xa uvavanyo lugubungela uluhlu olubanzi lwee-frequency. Imida yazo ibandakanya ukunyuswa okuphakathi, ubungakanani bomzimba kwii-frequency eziphantsi kunye notshintsho lwe-radiation-pattern ukuya kwisiphelo esiphezulu sebhendi.

Indlela yokukhetha i-Antenna yeBiconical

Qala ngoluhlu lweefrikhwensi ezifunekayo, uze uthelekise i-VSWR, i-gain, i-polarization, uzinzo lwepateni, uhlobo lwesixhumi, ukuphathwa kwamandla kunye nobukhulu boomatshini. Umgama wovavanyo, ukujongwa kokufakelwa kunye nendawo engqongileyo kufuneka kuqwalaselwe kuba izakhiwo ezikufutshane zinokuchaphazela ukulinganiswa kwe-broadband.

Hlola iiRF MISO'sizisombululo ze-antenna ezimbini, kuqukaI-RM-BCA812-2 ye-8-12 GHzkwaye iI-RM-BCA2428-4 ye-24-28 GHz. Kwimodeli ehambelana noluhlu lwakho lweefrikhwensi kunye nokuseta uvavanyo,nxibelelana ne-RF MISO.
