Log Periodic Antenna 8dBi Type. Pezani, 0.3-2GHz Frequency Range RM-LPA032-8

Mlongoti wa log-periodic ndi mlongoti wapadera wa burodibandi womwe magetsi ake, monga impedance ndi mawonekedwe a radiation, amabwereza nthawi ndi nthawi ndi logarithm ya ma frequency. Kapangidwe kake kakang'ono kamene kamakhala ndi zinthu zingapo zazitsulo za dipole zautali wosiyanasiyana, zomwe 交叉-zolumikizidwa ndi mzere wodyetsa, kupanga mawonekedwe a geometric omwe amakumbukira fupa la nsomba.

Mfundo yake yogwiritsira ntchito imadalira lingaliro la "gawo logwira ntchito". Pamafupipafupi ogwiritsira ntchito, gulu lokha la zinthu zomwe zili ndi kutalika pafupi ndi theka-wavelength zimakondwera bwino komanso zimakhala ndi mphamvu zowonongeka. Mafupipafupi akusintha, dera logwira ntchitoli limayenda motsatira dongosolo la mlongoti, ndikupangitsa kuti bandeji yake igwire ntchito.

Ubwino waukulu wa mlongoti uwu ndi bandwidth yake yotakata kwambiri, yomwe nthawi zambiri imafika 10: 1 kapena kupitilira apo, ndikuchita bwino pagulu lonselo. Zopinga zake zazikulu ndizomwe zimakhala zovuta komanso kupindula pang'ono. Imagwiritsidwa ntchito kwambiri polandirira kanema wawayilesi, kuyang'anira mawonedwe amtundu wathunthu, kuyesa kwa Electromagnetic Compatibility (EMC), ndi njira zoyankhulirana zomwe zimafunikira kuti pakhale mawilo ambiri.
