Vivaldi Antenna: Lub Ntsiab Cai Ua Haujlwm, Cov Yam Ntxwv thiab Cov Ntawv Thov

Lub kav hlau txais xov Vivaldi, tseem hu ua lub kav hlau txais xov tapered slot, yog lub kav hlau txais xov broadband directional uas siv dav hauv RF, microwave, radar, electronic warfare, measurement, thiab wireless testing systems. Nws lub qhov aperture tapered tshwj xeeb tso cai rau lub zog electromagnetic hloov maj mam los ntawm cov qauv xa mus rau qhov chaw dawb, pab lub kav hlau txais xov ua tiav kev ua haujlwm broadband thiab kev xa hluav taws xob directional.

Piv nrog ntau lub antennas resonant uas tau ua kom zoo dua nyob ib puag ncig qhov zaus nqaim, Vivaldi antennas siv cov qauv nthwv dej. Qhov no ua rau lawv nyiam tshwj xeeb rau cov kab ke uas xav tau kev pab them nqi ntau zaus ua ke nrog kev teeb tsa yooj yim planar lossis hlau.

Lub Vivaldi Antenna Ua Haujlwm Li Cas?

Lub kav hlau txais xov Vivaldi yooj yim muaj ob sab ntug uas ua rau muaj qhov tapered. Lub qhov maj mam nthuav dav los ntawm thaj chaw pub zaub mov nqaim mus rau qhov dav dua.

Thaum lub zog RF nkag mus rau hauv lub kav hlau txais xov, lub nthwv dej hluav taws xob mus ncig raws lub qhov tapered. Thaum qhov dav ntawm lub qhov nce ntxiv, lub nthwv dej coj mus rau hauv qhov chaw dawb thiab feem ntau tawm mus rau qhov kawg qhib ntawm lub kav hlau txais xov.

Qhov kev hloov pauv maj mam no yog ib qho ntawm cov laj thawj tseem ceeb uas Vivaldi antennas tuaj yeem muab cov yam ntxwv broadband.

Qhov zaus siv tau qis dua yog cuam tshuam los ntawm qhov loj ntawm lub qhov thiab taper, thaum qhov kev ua tau zoo ntawm cov zaus siab dua nyob ntawm ntau yam xws li kev hloov pauv pub, taper geometry, qhov loj ntawm tus neeg coj, thiab kev tsim khoom raug.

Cov yam ntxwv ntawm kev tawg

Lub kav hlau txais xov Vivaldi feem ntau yog lub kav hlau txais xov kawg, txhais tau tias nws lub zog hluav taws xob tseem ceeb yog taw qhia rau qhov kawg qhib ntawm lub qhov qhib tapered.

Nws cov yam ntxwv ntawm kev tawg hluav taws xob nyob ntawm ntau yam kev tsim qauv, suav nrog:

Qhov dav ntawm qhov qhib
Qhov ntev thiab qhov profile ntawm taper
Cov qauv pub
Kev ua haujlwm zaus
Geometry ntawm av thiab tus neeg xyuas pib
Qhov ntev ntawm cov khoom siv kho tshuab

Thaum zaus hloov pauv, thaj chaw siv hluav taws xob zoo raws li cov qauv tapered kuj hloov pauv. Qhov no tso cai rau lub antenna ua haujlwm hla ntau qhov zaus sib txawv yam tsis tas yuav cia siab rau ib qho resonance nqaim.

Cov kav hlau txais xov Vivaldi feem ntau yog tsim los rau kev sib hloov polarization, txawm hais tias kev ua tau zoo ntawm kev sib hloov polarization nyob ntawm qhov geometry tshwj xeeb thiab kev npaj pub mis.

Cov Hom Phiaj Tseem Ceeb ntawm Vivaldi Antennas

Ntau qhov kev teeb tsa Vivaldi antenna feem ntau siv hauv RF engineering.

Lub Antenna Vivaldi Ib Txwm Muaj
Siv ib qho tapered slot tsim ntawm ob lub conductive cheeb tsam thiab yog ib qho ntawm cov kev siv ntau tshaj plaws.

Antenna Antipodal Vivaldi
Siv cov khoom siv hluav taws xob uas nyob rau sab nraud ntawm lub substrate dielectric. Qhov kev teeb tsa no tuaj yeem muab kev hloov pauv yooj yim los ntawm qee qhov kev xa xov mus rau qhov qhib hluav taws xob.

Lub Antenna Vivaldi Antipodal Balanced
Siv cov qauv ntau txheej sib npaug los txhim kho qhov sib npaug ntawm thaj chaw thiab cov yam ntxwv polarization hauv qee qhov kev siv broadband.

Cov kev teeb tsa sib txawv yuav raug xaiv raws li bandwidth, polarization, feed method, fabrication process, thiab system-integration requirements.

Cov Kev Ntsuas Tseem Ceeb Thaum Xaiv Vivaldi Antenna

Thaum xaiv lub kav hlau txais xov Vivaldi, qhov ntau zaus tsuas yog qhov pib xwb.

Qhov nce qhia tau tias lub kav hlau txais xov ua rau cov hluav taws xob sib sau ua ke zoo li cas rau pem hauv ntej.

VSWR qhia txog qhov sib phim impedance ntawm lub antenna thiab RF system. VSWR qis dua feem ntau txhais tau tias lub zog cuam tshuam tsawg dua.

Kev sib hloov pauv yuav tsum phim lub hom phiaj RF system kom txo qis kev sib hloov pauv polarization.

3 dB Beamwidth piav qhia txog qhov dav ntawm lub kaum sab xis ntawm lub teeb hluav taws xob tseem ceeb thiab tseem ceeb hauv radar, kev saib xyuas, thiab kev ntsuas kev taw qhia.

Kev Ua Haujlwm Cross-Polarization kuj tseem ceeb thaum qhov kev ntshiab ntawm polarization tseem ceeb.

Yuav tsum xav txog cov yam ntxwv ntawm lub tshuab xws li hom txuas, qhov loj ntawm lub kav hlau txais xov, qhov hnyav, cov qauv teeb tsa, thiab kev tswj hwm lub zog thaum lub sijhawm koom ua ke ntawm lub kaw lus.

Piv txwv li, RF MISO's RM-VA0212-6 Linear Polarized Vivaldi Antenna ua haujlwm ntawm 0.2 txog 1.2 GHz, muab 6 dBi qhov nce, siv linear polarization thiab N-Female interface, thiab tau teev tseg rau radar, kev sib txuas lus satellite, kev ua tsov rog hluav taws xob, thiab cov ntawv thov kev sim wireless siab.
