Lub kav hlau txais xov microwave, tseem hu ua xov tooj cua zaus kav hlau txais xov, yog ib hom transducer uas yog tsim los xa thiab txais cov teeb liab electromagnetic nyob rau hauv lub microwave zaus. Nws yog ib qho tseem ceeb ntawm kev sib txuas lus, xws li hauv kev sib txuas lus satellite, radar, thiab wireless systems.
Microwave antennas tuaj nyob rau hauv ntau yam duab thiab ntau thiab tsawg, nyob ntawm seb lawv daim ntawv thov tshwj xeeb. Feem ntau hom muaj xws li dipole, thaj, horn, parabolic, thiab helical kav hlau txais xov. Txhua hom muaj nws tus kheej tsim tshwj xeeb thiab yog optimized rau ib tug ntau yam ntawm frequencies, hwj chim theem, thiab kev taw qhia cov khoom.
Dipole antennas yog hom yooj yim tshaj plaws ntawm microwave kav hlau txais xov thiab yog tsim los ntawm ob lub xov hlau los yog rods uas yog ib feem ntawm lub wavelength ntev. Lawv yog omnidirectional thiab siv rau kev sib kis thiab txais tos. Patch antennas feem ntau yog tiaj tus thiab siv rau hauv cov ntawv thov uas yuav tsum muaj tus kav hlau txais xov qis, xws li hauv xov tooj ntawm tes, Wi-Fi routers, thiab satellite TV receivers.
Horn antennas yog zoo li lub funnel thiab yog siv rau high-power kis tau tus mob thiab tsawg-tsawg txais tos. Cov kav hlau txais xov Parabolic yog cov tais diav thiab siv rau kev sib txuas lus ntev mus rau qhov chaw, xws li hauv kev sib txuas lus satellite thiab xov tooj cua telescopes. Helical antennas yog coiled thiab siv rau hauv cov ntawv thov uas yuav tsum tau muaj lub voj voog polarization, xws li hauv GPS systems thiab satellite kev sib txuas lus.
Microwave antennas yog cov khoom tseem ceeb ntawm cov tshuab kev sib txuas lus niaj hnub no, thiab raws li kev siv thev naus laus zis, lawv qhov tseem ceeb tsuas yog txuas ntxiv mus ntxiv. Lawv ua kom muaj kev sib txuas lus thoob plaws qhov deb heev thiab siv ntau yam kev siv, suav nrog tab sis tsis txwv rau huab cua huab cua, kev tswj hwm huab cua, kev sib txuas lus tub rog, thiab lub ntiaj teb qhov chaw.
Hauv cov ntsiab lus, microwave kav hlau txais xov yog qhov tseem ceeb rau kev sib txuas lus niaj hnub thiab ua kom muaj kev sib txuas lus thoob plaws qhov deb. Lawv tuaj nyob rau hauv ntau yam duab thiab ntau thiab tsawg thiab yog optimized rau tej daim ntaub ntawv. Raws li kev siv thev naus laus zis hloov zuj zus, lawv qhov tseem ceeb tsuas yog nce ntxiv, thiab lawv tseem yuav ua lub luag haujlwm tseem ceeb hauv kev sib txuas lus.
