Log Kauv Kav hlau txais xov 3dBi Hom. Tau, 1-10 GHz Zaus Ntau Yam RM-LSA110-3

Tus kav hlau txais xov log-kauv yog ib lub kav hlau txais xov angular classic uas nws cov caj npab hlau yog txhais los ntawm logarithmic kauv nkhaus. Thaum pom kev zoo ib yam li Archimedean kauv, nws cov qauv lej tshwj xeeb ua rau nws muaj tseeb "ntau zaus-xov tooj cua ywj pheej."

Nws txoj kev ua haujlwm yog nyob ntawm nws tus kheej-ua tiav cov qauv (hlau thiab huab cua qhov sib txawv yog zoo ib yam) thiab nws qhov tseeb angular. Lub kav hlau txais xov lub active cheeb tsam ntawm ib tug ntau zaus yog ib lub nplhaib-zoo li tus cheeb tsam nrog ib ncig ntawm kwv yees li ib tug wavelength. Raws li kev ua haujlwm zaus hloov pauv, thaj chaw nquag no txav tau yooj yim raws li cov caj npab kauv, tab sis nws cov duab thiab cov yam ntxwv hluav taws xob nyob twj ywm, ua kom muaj qhov dav dav dav.

Qhov txiaj ntsig tseem ceeb ntawm lub kav hlau txais xov no yog nws qhov kev ua tau zoo ntawm ultra-wideband (bandwidths ntawm 10: 1 lossis ntau dua) thiab nws lub peev xwm muaj peev xwm ua kom lub voj voog polarized tsis muaj zog. Nws qhov teeb meem tseem ceeb yog qhov nce qis thiab qhov xav tau rau kev sib koom ua ke pub noj sib luag. Nws yog siv dav hauv cov ntawv thov uas xav tau kev ua haujlwm dav dav, xws li Electronic Countermeasures (ECM), broadband kev sib txuas lus, thiab kev soj ntsuam spectrum.
