Hauv kev tsim cov kav hlau txais xov microwave, qhov kev xav tau zoo tshaj plaws yuav tsum sib npaug ntawm kev ua tau zoo thiab kev ua tau zoo. Txawm hais tias kev nce qib siab tuaj yeem txhim kho lub teeb liab lub zog, nws yuav ua rau muaj teeb meem xws li qhov loj me, kev sib tw kub dissipation thiab nce nqi. Cov hauv qab no yog cov ntsiab lus tseem ceeb:
1. Sib piv nce nrog daim ntawv thov
5G puag chaw nres tsheb (millimeter yoj AAU):24-28 dBi, xav taunqus brazingdej txias phaj los xyuas kom meej lub zog ua haujlwm ntev.
Kev sib txuas lus satellite (Ka band):40-45 dBi, cia siab rau faus tooj liab tube dej txias los daws qhov teeb meem kub dissipation ntawm cov kav hlau txais xov loj aperture.
Hluav taws xob ua tsov rog / radar:20-30dBi, siv do txhuam vuam ua kua txias kom haum rau siab dynamic tshav kub load.
Kev xeem EMC:10-15 dBi, zoo tib yam vuam kub dab dej tuaj yeem ua tau raws li qhov xav tau.

2. Engineering txwv ntawm kev nce siab
Thaum tshav kub kub dissipation bottleneck: Kav hlau txais xov siab tshaj 25dBi feem ntau yuav tsum tau ua kua txias (xws li lub tshuab nqus tsev brazing los yog do txhuam vuam dej txias phaj), txwv tsis pub lub hwj chim muaj peev xwm raug txwv.
Kev txwv loj: Cov kav hlau txais xov siab tshaj 30dBi tuaj yeem tshaj 1 meter hauv Ka band, thiab cov qauv tsim yuav tsum tau ua kom zoo dua.
Tus nqi tseem ceeb: Rau txhua txhua 3dB nce hauv qhov nce, tus nqi ntawm cov cua txias yuav nce 20% -30%.

3. Cov lus qhia ua kom zoo
Ua ntej yuav tsum tau ua kom haum rau daim ntawv thov thiab zam dhau kev nrhiav kev nce siab.
Cov tshuaj txias txias txiav txim siab lub zog muaj peev xwm, thiab cov kav hlau txais xov siab yuav tsum tau nruab nrog cov cua txias (xws li kua txias).
Ntsuas bandwidth thiab nce. Narrowband systems tuaj yeem nrhiav kev nce siab dua, thiab broadband systems yuav tsum ua kom muaj kev sib haum xeeb.
Cov lus xaus: Qhov kev pom zoo yog nyob ntawm daim ntawv thov tshwj xeeb, feem ntau ntawm 20-35dBi, thiab yuav tsum tau ua ke nrog cov tshuab cua txias siab heev (xws li lub tshuab nqus tsev vacuum lossis txhuam txhuam vuam dej txias) kom ntseeg tau tias kev ua haujlwm ruaj khov.
