Rau cov ntsuas ntsuas ntawm ANDENNY ROuce Ncaj Nceesffient D, peb txhais nws los ntawm qhov ntev ntawm cov nqaj hlau loj ntau ntau.
Direction D yog qhov sib piv ntawm qhov siab tshaj plaws radiated p (θ, φ) max rau nws tus lej nyob hauv 1. Cov lej sib npaug yog li nram no:
Ntxiv rau, Directivity D tuaj yeem suav tau los ntawm cov qauv hauv qab no:
D = 4 pi / ω _a
Hauv kev xyaum, Logarithmic xam ntawm d yog feem ntau siv los sawv cev cov ditreal nce ntawm ib tus kav hlau txais xov xwm:
D = 10 log d
Qhov saum toj no Directivity D yuav tau txhais raws li qhov sib piv ntawm lub kheej li cas (4π radn) nqaj hlau ntau ω _a. Piv txwv li, yog tias ib tug kav hlau txais xov hluav taws xob tsuas yog mus rau sab sauv Hemispherical thiab nws cov nqaj sib tw yog ω _a = 2 steriadity yog:
Yog tias lub logarithm ntawm ob tog ntawm txoj kab sib npaug saum toj no yog coj los, lub kav hlau txais xov cov kev coj kom muaj txiaj ntsig rau isotropy tuaj yeem tau txais. Nws yuav tsum raug sau tseg tias qhov no nce tuaj yeem muaj kev cuam tshuam txog lub kav hlau txais xov hluav taws xob, txij li kev kis lasbicy tsis suav hais tias yog qhov nce zoo. Cov kev xam tau yog raws li hauv qab no:
3.01 chav kawm:: DBI D = 10 log 2 cov khoom siv
Lub kav hlau txais xov cov chav nyob yog DBI thiab DBD, qhov twg:
DBI: Yog qhov tau los ntawm lub Antenna RADSION TXOJ CAI RAU LUB SIJHAWM, vim hais tias tus taw tes muaj _A = 4π thiab qhov kev taw qhia qhov tseeb yog 0dB;
DBD: yog qhov nce ntawm Antenna RADVE RADIVATION rau ib nrab-yoj Dipole kav hlau txais xov;
Cov lus hloov pauv hloov dua tshiab ntawm DBI thiab DBD yog:
