Microstrip kav hlau txais xovyog hom tshiab ntawm microwavekav hlau txais xovuas siv conductive strips luam tawm ntawm ib tug dielectric substrate raws li tus kav hlau txais xov radiating unit. Microstrip antennas tau siv dav hauv kev sib txuas lus niaj hnub vim lawv qhov me me, lub teeb yuag, tsis tshua muaj profile, thiab kev sib koom ua ke yooj yim.
Yuav ua li cas microstrip kav hlau txais xov ua haujlwm
Lub hauv paus ntsiab lus ua haujlwm ntawm microstrip kav hlau txais xov yog ua raws li kev sib kis thiab hluav taws xob ntawm electromagnetic tsis. Nws feem ntau muaj hluav taws xob thaj, dielectric substrate thiab hauv av phaj. Cov hluav taws xob hluav taws xob yog luam tawm ntawm qhov chaw ntawm dielectric substrate, thaum lub phaj hauv av nyob rau sab nraud ntawm dielectric substrate.
1. Radiation thaj: Cov kab hluav taws xob yog ib feem tseem ceeb ntawm microstrip kav hlau txais xov. Nws yog ib txoj hlua hlau ua lub luag haujlwm rau kev ntes thiab tawg electromagnetic tsis.
2. Dielectric substrate: Lub dielectric substrate feem ntau yog ua los ntawm cov khoom siv qis, siab-dielectric-constant, xws li polytetrafluoroethylene (PTFE) los yog lwm yam khoom siv ceramic. Nws txoj haujlwm yog los txhawb cov hluav taws xob hluav taws xob thiab ua haujlwm nruab nrab rau kev nthuav tawm electromagnetic yoj.
3. Cov phaj hauv av: Cov phaj hauv av yog txheej hlau loj dua nyob rau sab nraud ntawm dielectric substrate. Nws tsim capacitive coupling nrog cov hluav taws xob thaj thiab muab qhov tsim nyog electromagnetic teb tis.
Thaum lub teeb liab microwave tau pub rau hauv microstrip kav hlau txais xov, nws tsim nthwv dej ntawm cov hluav taws xob hluav taws xob thiab cov phaj hauv av, uas ua rau cov hluav taws xob hluav taws xob tsis zoo. Kev ua haujlwm hluav taws xob thiab cov qauv ntawm tus kav hlau txais xov microstrip tuaj yeem hloov kho los ntawm kev hloov cov duab thiab qhov loj ntawm thaj thiab cov yam ntxwv ntawm dielectric substrate.

Qhov txawv ntawm microstrip kav hlau txais xov thiab thaj kav hlau txais xov
Patch kav hlau txais xov yog ib daim ntawv ntawm microstrip kav hlau txais xov, tab sis muaj qee qhov sib txawv ntawm cov qauv thiab kev ua haujlwm ntawm ob:
1. Cov qauv sib txawv:
Microstrip kav hlau txais xov: feem ntau muaj cov hluav taws xob hluav taws xob, lub dielectric substrate thiab cov phaj hauv av. Lub thaj yog tshem tawm ntawm lub dielectric substrate.
Patch kav hlau txais xov: Cov khoom siv hluav taws xob ntawm thaj kav hlau txais xov yog txuas ncaj qha mus rau dielectric substrate, feem ntau tsis muaj qhov pom tseeb raug tshem tawm.
2. Txoj kev pub mis:
Microstrip kav hlau txais xov: Cov khoom noj feem ntau yog txuas nrog lub tshuab hluav taws xob los ntawm kev sojntsuam lossis kab microstrip.
Patch kav hlau txais xov: Cov txheej txheem pub mis muaj ntau haiv neeg, uas tuaj yeem yog kev noj zaub mov, qhov pub noj los yog pub coplanar, thiab lwm yam.
3. Radiation efficiency:
Microstrip kav hlau txais xov: Txij li thaum muaj qee qhov sib txawv ntawm cov hluav taws xob hluav taws xob thiab cov phaj hauv av, tej zaum yuav muaj qee qhov tsis zoo ntawm huab cua, uas cuam tshuam rau cov hluav taws xob hluav taws xob.
Patch antenna: Cov khoom siv hluav taws xob ntawm thaj kav hlau txais xov yog sib txuas nrog cov dielectric substrate, uas feem ntau muaj hluav taws xob ntau dua.
4. Bandwidth kev ua tau zoo:
Microstrip kav hlau txais xov: Bandwidth kuj nqaim, thiab bandwidth yuav tsum tau nce ntxiv los ntawm kev tsim kho kom zoo.
Patch kav hlau txais xov: Dav bandwidth tuaj yeem ua tiav los ntawm kev tsim ntau yam qauv, xws li ntxiv radar tav los yog siv cov txheej txheem ntau txheej.
5.Cov sijhawm thov:
Microstrip kav hlau txais xov: haum rau cov ntawv thov uas yuav tsum nruj rau qhov siab profile, xws li kev sib txuas lus satellite thiab kev sib txuas lus ntawm tes.
Patch antennas: Vim lawv cov qauv sib txawv, lawv tuaj yeem siv tau rau hauv ntau hom kev siv, suav nrog radar, wireless LANs, thiab kev sib txuas lus ntawm tus kheej.
Hauv kev xaus
Microstrip antennas thiab patch antennas yog ob qho tib si siv cov kav hlau txais xov microwave hauv kev sib txuas lus niaj hnub, thiab lawv muaj lawv tus kheej cov yam ntxwv thiab qhov zoo. Microstrip antennas ua tau zoo nyob rau hauv qhov chaw txwv tsis pub siv vim lawv qhov profile qis thiab kev sib koom ua ke yooj yim. Patch antennas, ntawm qhov tod tes, muaj ntau dua nyob rau hauv daim ntawv thov uas yuav tsum tau dav bandwidth thiab high efficiency vim lawv high radiation efficiency thiab designability.
