Kev Txheeb Xyuas Txog Khoom Thiab Tshuab

Lub kav hlau txais xov microstrip yog lub kav hlau txais xov planar uas tsim los ntawm ib daim ntaub thaiv hluav taws xob conductive, ib lub substrate dielectric, thiab ib lub dav hlau hauv av. Daim ntaub feem ntau yog luam tawm rau ib sab ntawm lub substrate, thaum lub dav hlau hauv av muab tso rau sab nraud. Cov qauv no ua rau lub kav hlau txais xov nyias, sib dua, thiab tsim nyog rau kev teeb tsa rau ntawm cov platform tiaj tus lossis me ntsis nkhaus.

Hauv kev tsim kho RF, cov kav hlau txais xov microstrip muaj nqis vim tias lawv tuaj yeem koom ua ke nrog cov voj voog microwave, phased arrays, radomes, thiab compact system housings. Lawv cov yam ntxwv ntawm kev hluav taws xob tuaj yeem hloov kho los ntawm thaj geometry, cov khoom siv substrate, txoj kev pub mis, kev npaj array, thiab kev teeb tsa kho tshuab.

Cov Qauv Tseem Ceeb ntawm Microstrip Antenna

Ib lub kav hlau txais xov microstrip feem ntau muaj peb txheej tseem ceeb. Daim hlau sab saud ua haujlwm ua lub ntsiab lus hluav taws xob. Lub substrate dielectric txhawb nqa daim ntawv thiab cuam tshuam rau bandwidth, kev ua haujlwm zoo, thiab qhov loj me. Lub dav hlau hauv qab pab txhais tus cwj pwm hluav taws xob thiab cais lub kav hlau txais xov ntawm qhov chaw teeb tsa.

Dielectric substrate	Xaiv raws li RF poob, dielectric tas mus li, thickness, bandwidth, thiab cov kev cai ib puag ncig.
Lub dav hlau hauv av	Muab ib lub dav hlau siv thiab pab txhawb rau kev ua haujlwm ntawm lub zog hluav taws xob ruaj khov.
Cov qauv pub	Tej zaum yuav siv tau kab microstrip, coaxial probe, aperture coupling, lossis proximity coupling nyob ntawm lub hom phiaj tsim.

Microstrip Antenna Ua Haujlwm Li Cas?

Thaum lub zog RF raug pub rau hauv daim thaj, lub zog hluav taws xob tau tsim ntawm daim thaj thiab lub dav hlau hauv av. Kev tawg feem ntau tshwm sim ze ntawm ntug ntawm daim thaj, qhov twg lub zog ntug txuas mus rau qhov chaw ib puag ncig.

Qhov zaus ua haujlwm muaj feem cuam tshuam nrog qhov loj ntawm daim thaj, qhov tsis hloov pauv ntawm lub substrate, thiab qhov tuab ntawm lub substrate. Rau daim thaj plaub fab, qhov ntev ntawm lub resonant feem ntau muaj feem cuam tshuam nrog kwv yees li ib nrab ntawm qhov wavelength uas tau coj hauv lub substrate.

Hauv cov qauv tsim tiag tiag, qhov ntev kawg yuav tsum tau ua kom zoo tshaj plaws vim tias qhov kev thauj khoom dielectric, qhov chaw pub, tsev, cov khoom siv radome, thiab cov qauv hlau nyob ze tuaj yeem cuam tshuam rau kev ua tau zoo ntsuas.
