Kav hlau txais xov nce: Qhov nce coefficient yog qhov ntsuas uas ntsuas lub zog hloov pauv thiab cov yam ntxwv ntawm tus kav hlau txais xov. Nws txhais tau tias:
Cov khoom ntawm directional coefficient thiab kav hlau txais xov efficiency yog denoted li: D yog lub directional coefficient thiab yog tus kav hlau txais xov efficiency. Nws tuaj yeem pom tau tias qhov ntau dua ntawm cov kav hlau txais xov directional coefficients, qhov siab dua qhov nce coefficient. Thiab nws qhov tseem ceeb ntawm lub cev: qhov nce coefficient ntawm tus kav hlau txais xov piav qhia ntau zaus uas tus kav hlau txais xov nthuav dav nws cov zis hluav taws xob nyob rau hauv qhov siab tshaj plaws hluav taws xob kev taw qhia piv rau cov kav hlau txais xov tsis muaj qhov zoo tagnrho. Nws kuj tseem tuaj yeem nkag siab zoo li qhov piv ntawm tus kav hlau txais xov coj mus rau qhov zoo tshaj plaws omnidirectional kav hlau txais xov (nws cov hluav taws xob sib npaug hauv txhua qhov kev qhia) tsim cov teeb liab ntawm qee qhov me me ntawm qee qhov taw tes hauv qee qhov deb. Kav hlau txais xov efficiency: Kav hlau txais xov efficiency yog txhais raws li qhov piv ntawm tus kav hlau txais xov hluav taws xob hluav taws xob rau lub zog hluav taws xob.
Cov hluav taws xob tiv thaiv R ntawm cov kav hlau txais xov feem ntau yog siv los ntsuas lub peev xwm ntawm cov kav hlau txais xov kom tawg lub zog. Kev tiv thaiv hluav taws xob ntawm cov kav hlau txais xov yog qhov muaj nuj nqis virtual txhais raws li hauv qab no: nrog tus resistor R, thaum tam sim no dhau los ntawm nws yog sib npaug rau qhov siab tshaj plaws tam sim no ntawm tus kav hlau txais xov, lub zog poob yog sib npaug rau nws lub zog hluav taws xob. Obviously, qib ntawm hluav taws xob tiv thaiv yog ib qho tseem ceeb qhia los ntsuas lub peev xwm hluav taws xob ntawm lub kav hlau txais xov, uas yog, qhov loj dua qhov hluav taws xob tiv thaiv, qhov muaj zog ntawm cov hluav taws xob muaj peev xwm ntawm lub kav hlau txais xov.
Peb cov khoom muag zoo tshaj plaws npog ntau homONUseries khoom, nrog rau ACONU/ kev sib txuas lusONU/ ntseONU/ lub thawvONU, etc. Tag nrho covONUseries cov khoom siv tuaj yeem siv rau kev xav tau hauv network hauv ntau yam xwm txheej.
