ANT051 Four Element Spiral Antenna Array
| Moetapele-mw | Selelekela ho Four Element Spiral Antenna Array |
E hlahisa Leader microwave tech.,(leader-mw) mekhoa e mecha ea morao-rao ea theknoloji ea antenna - mefuta e mengata e tsitsitseng ea li-antenna tsa stereo. Letoto lena la maemo a holimo le etselitsoe ho fetola tsela eo re bonang le ho sebelisa litsamaiso tsa li-antenna, ho fana ka ts'ebetso e ke keng ea lekanngoa le ho feto-fetoha ha maemo ka moralo o kopaneng le o sebetsang hantle.
Pelo ea sehlopha sena sa phetoho ke karolo ea helical antenna, e kopantsoeng ka hloko le sebopeho sa sethala se tapered. Sebopeho se na le sebaka se ka holimo le mahlakoreng a mangata, e 'ngoe le e' ngoe e hokahane le moeli oa sebaka se ka holimo. Mahlakore a mahlakore a haufi le 'ona a hokahane, a theha sethala se se nang moeli le se matla bakeng sa likarolo tsa antenna.
Moralo o ikhethileng oa sebopeho sa sethala sa tapered se lumella likarolo tsa antenna tsa helical hore li behoe ka holimo le ka mahlakoreng, ho eketsa ts'ireletso ea marang-rang le ts'ebetso. Tlhophiso ena e nolofalletsa sehlopha ho ntša marako a mangata ka mokhoa oa stereoscopic, ka hona ho ntlafatsa bokhoni ba ho amohela le ho fetisetsa tsamaiso ea antenna.
E 'ngoe ea likarolo tsa bohlokoa tsa sebopeho sa sethala se tapered ke sebopeho se tloaelehileng sa polygonal sa bokaholimo, se ntlafatsang kabo e ts'oanang ea likarolo tsa antenna le ho ntlafatsa ts'ebetso e akaretsang ea sehlopha. Sena se tiisa hore sehlopha se ka fana ka matla a mats'oao a ts'oanang le a ts'epahalang ho pholletsa le lits'ebetso le libaka tse fapaneng.
