Xaiv ib qhoTuam Tshoj chaw tsim khoom siv ob lub antennatsis yog tsuas yog ib qho teeb meem ntawm kev sib piv cov zaus ntau yam xwb. Rau kev sim RF broadband, lub kav hlau txais xov kuj yuav tsum muab kev sib phim impedance ruaj khov, kev kwv yees tus cwj pwm hluav taws xob, cov khoom sib txuas tsim nyog, thiab cov qhov ntev uas haum rau kev teeb tsa ntsuas. Cov ntsiab lus no cuam tshuam ncaj qha rau kev rov ua dua hauv kev sim EMC / EMI, kev ntsuas kav hlau txais xov, kev saib xyuas teeb liab, thiab kev koom ua ke ntawm lub kaw lus.
RF MISO tsim thiab muab cov kev daws teeb meem broadband horn antenna rau RF engineers, system integrators, laboratories, thiab equipment manufacturers. Cov qauv sawv cev hauv qab no ua ke suav nrog0.4 txog 40 GHz, tso cai rau cov neeg siv xaiv lub antenna rau ib qho kev ua haujlwm band es tsis txhob xav tias ib lub antenna npog tag nrho cov ntau yam.
Vim li cas Ob Chav-Ridged Horn Antennas Siv Rau Kev Ntsuas Broadband RF
Ib lub qauv waveguide ob chav txuas ntxiv qhov bandwidth siv tau ntawm lub horn antenna thaum khaws cov hluav taws xob directional thiab linear polarization. Kev sib xyaw ua ke no ua rau lub antenna muaj txiaj ntsig thaum lub kaw lus kuaj yuav tsum ua haujlwm hla ntau zaus yam tsis tas hloov antennas ntau zaus.
Cov kev siv feem ntau suav nrog kev sim cov pa phem tawm, kev ntsuam xyuas EMC/EMI, kev ntsuas qhov nce ntawm lub antenna thiab cov qauv hluav taws xob, kev xa thiab txais cov teeb liab broadband, kev saib xyuas, kev soj ntsuam, thiab kev nrhiav kev taw qhia.

Pib nrog qhov zaus ua haujlwm qis tshaj plaws thiab siab tshaj plaws uas lub kaw lus xav tau. Qhov ntau dua tsis zoo dua li qub: lub kav hlau txais xov xaiv yuav tsum phim qhov qhab nia xeem tiag tiag thaum ua tau raws li qhov nce, qhov dav ntawm lub teeb, qhov loj me, thiab cov xwm txheej txuas uas xav tau. Thaum muaj ntau txoj kab sib txuas, piv qhov kev pauv pauv ntawm ib tus qauv broadband thiab ntau lub kav hlau txais xov uas tau kho kom zoo rau qhov ntau dua.
2. Kev sib phim ntawm qhov nce thiab impedance
Qhov nce ntxiv cuam tshuam rau kev sib txuas nyiaj txiag thiab lub zog ntawm thaj chaw, thaum VSWR qhia txog qhov ua tau zoo ntawm lub zog xa mus ntawm kab pub thiab lub kav hlau txais xov. Cov nqi luam tawm yuav tsum tau nyeem ua ke nrog cov phiaj xwm raws li zaus thaum twg ua tau. Cov kws ua haujlwm RF kuj tseem yuav tsum paub meej tias cov nqi tau hais yog qhov ib txwm muaj lossis lav thiab tshuaj xyuas cov ntaub ntawv tam sim no rau qhov kev teeb tsa tseeb uas tau yuav.
3. Kev ua haujlwm ntawm kev tawg thiab kev sib hloov polarization
Kev them nqi broadband ib leeg xwb tsis txhais tau tias lub antenna ua haujlwm tau zoo. Cov qauv hluav taws xob, qhov dav ntawm lub teeb, kev sib cais ntawm cov polarization, thiab kev taw qhia polarization linear kuj tseem ceeb ib yam hauv kev ntsuas thiab kev saib xyuas. Cov yam ntxwv no pab txiav txim siab qhov geometry ntawm kev xeem, qhov yuav tsum tau ua kom sib npaug, thiab kev tsis paub meej ntawm kev ntsuas.
4. Kev sib txuas thiab kev sib koom ua ke
Hom txuas yuav tsum sib xws nrog lub zaus ua haujlwm, kev sib dhos cable, thiab cov khoom siv kuaj. Qhov loj me tag nrho, qhov hnyav, kev teeb tsa, thiab kev teeb tsa antenna kuj cuam tshuam rau kev teeb tsa chamber, kev teeb tsa qhov chaw, thiab kev teeb tsa kev kuaj portable. Daim duab kos tam sim no yog qhov tseem ceeb thaum lub antenna yuav raug koom ua ke rau hauv lub fixture lossis platform uas twb muaj lawm.
5. Cov ntaub ntawv pov thawj ntawm chaw tsim khoom thiab kev sib txuas lus txog kev siv tshuab
Ib tus neeg muag khoom siv broadband horn antenna uas muaj peev xwm yuav tsum muab cov lus qhia tshwj xeeb rau tus qauv thiab kev sib txuas lus meej. Ua ntej yuav khoom, qhia qhov zaus uas xav tau, daim ntawv thov, lub hom phiaj nce, qhov txuas, qib fais fab, kev txwv kev teeb tsa, thiab cov xwm txheej ib puag ncig. Qhov no muab cov ntaub ntawv txaus rau cov chaw tsim khoom los tshuaj xyuas seb tus qauv txheem puas tsim nyog.
