| Leader-mw | kev ntsuas ntawm kav hlau txais xov |
Rau kev ntsuas qhov ntsuas ntawm tus kav hlau txais xov ncaj qha coefficient D, peb txhais nws los ntawm qhov ntev ntawm tus kav hlau txais xov hluav taws xob hluav taws xob ntau.
Directivity D yog qhov sib piv ntawm qhov siab tshaj plaws radiated zog ceev P(θ,φ) Max rau nws tus nqi txhais tau tias P(θ,φ)av ntawm ib tug kheej kheej nyob rau hauv cheeb tsam deb, thiab yog ib tug dimensionless piv ntau dua los yog sib npaug rau 1 . Cov mis laij lej yog raws li nram no:
Tsis tas li ntawd, kev ncaj ncees D tuaj yeem xam los ntawm cov qauv hauv qab no:
D = 4 PI / Ω _A
Hauv kev xyaum, kev suav logarithmic ntawm D feem ntau yog siv los sawv cev qhov nce ntawm tus kav hlau txais xov:
D = 10 log d
Cov lus qhia saum toj no D tuaj yeem txhais raws li qhov sib piv ntawm qhov sib txawv (4π rad²) kav hlau txais xov kab ntau yam ω _A. Piv txwv li, yog tias tus kav hlau txais xov radiates tsuas yog mus rau sab sauv hemispherical qhov chaw thiab nws cov kab teeb yog ω _A = 2π rad², ces nws txoj kev ncaj qha yog:
Yog tias lub logarithm ntawm ob sab ntawm qhov sib npaug saum toj no raug coj mus, tus kav hlau txais xov txoj kev nce qib ntawm isotropy tuaj yeem tau txais. Nws yuav tsum raug sau tseg tias qhov kev nce no tsuas yog cuam tshuam txog tus kav hlau txais xov cov qauv kev taw qhia hluav taws xob, hauv chav tsev ntawm dBi, txij li kev sib kis tau zoo tsis suav tias yog qhov txiaj ntsig zoo tshaj plaws. Cov txiaj ntsig ntawm kev suav yog raws li hauv qab no:
3.01 chav kawm: : dBi d = 10 log 2 khoom
Tus kav hlau txais xov nce units yog dBi thiab dBd, qhov twg:
DBi: yog qhov nce tau los ntawm cov kav hlau txais xov hluav taws xob txheeb ze rau qhov chaw taw tes, vim tias qhov chaw taw tes muaj ω _A = 4π thiab qhov taw qhia nce yog 0dB;
DBd: yog qhov nce ntawm cov kav hlau txais xov hluav taws xob txheeb ze rau ib nrab-yoj dipole kav hlau txais xov;
Cov mis hloov pauv ntawm dBi thiab dBd yog:
