Helical Spiral Antenna 12dBi Mtundu wa Gain, 1.95-2.1 GHz Frequency Range RM-HSA1921-12R

Helical Spiral Antenna 12dBi Type. Gain, 1.95-2.1 GHz Frequency Range RM-HSA1921-12R Chithunzi Chowonetsedwa

Kufotokozera Kwachidule:

RM-HSA1921-12R ndi antenna yozungulira yozungulira ya dzanja lamanja (RHCP), yomwe imagwira ntchito kuyambira 1.95 mpaka 2.1GHz yokhala ndi 12dB Type gain. komanso VSWR yotsika 1.5:1 yokhala ndi N Female. Ili ndi gain yayikulu, kapangidwe kosavuta, komanso kukula kochepa, pamodzi ndi polarization yozungulira ya dzanja lamanja, zomwe zimapangitsa kuti ikhale yoyenera kudyetsa reflector, kuyeza antenna, ndi ntchito zina.

Yapitayi: Antena Yozungulira Yachiwiri Yokhala ndi Polarized Horn 15 dBi Mtundu Wopambana, 2-6GHz Frequency Range RM-DCPHA26-15

Antena yozungulira yozungulira ndi antena yakale yosagwiritsa ntchito ma frequency ambiri yomwe imadziwika ndi mawonekedwe ake a ultra-wideband. Kapangidwe kake kamakhala ndi manja awiri kapena kuposerapo achitsulo omwe amazungulira kuchokera pakati pa malo operekera chakudya, ndipo mitundu yodziwika bwino ndi Archimedean spiral ndi logarithmic spiral.

Kugwira ntchito kwake kumadalira kapangidwe kake kodziyimira pawokha (komwe mipata yachitsulo ndi mpweya ili ndi mawonekedwe ofanana) ndi lingaliro la "dera logwira ntchito". Pafupipafupi inayake, dera longa mphete pa spiral yokhala ndi circle ya wavelength pafupifupi imodzi imasangalatsidwa ndipo imakhala dera logwira ntchito lomwe limayang'anira kuwala. Pamene frequency ikusintha, dera logwira ntchito ili limayenda motsatira mikono yozungulira, zomwe zimapangitsa kuti mawonekedwe amagetsi a antenna akhalebe olimba pa bandwidth yayikulu kwambiri.

Ubwino waukulu wa antenna iyi ndi bandwidth yake yotakata kwambiri (nthawi zambiri 10:1 kapena kuposerapo), kuthekera kwake kozungulira polarization, komanso mawonekedwe okhazikika a radiation. Zoyipa zake zazikulu ndi kukula kwake kwakukulu komanso nthawi zambiri zimakhala zochepa. Imagwiritsidwa ntchito kwambiri pakugwiritsa ntchito ma ultra-wideband performance, monga electronic warfare, broadband communications, time-domain measurements, ndi radar systems.
