Phaello e Phahameng ea L-Band Directional Spiral Antenna /Helical Antenna

Lenaka la helical/spiral antenna ke lenakana le entsoeng ka terata ea tšepe ea tšepe, e feptjoang ke thapo ea coaxial. Taelo ea eona ea mahlaseli e itšetlehile ka selikalikoe sa terata ea helical, e ka bang perpendicular ho axis kapa hammoho le axis. Likarolo tsa mantlha tsa antenna ea helical ke hore e khanya haufi le axis, e hlahisa maqhubu a polarized circularly, hajoale e ajoa ka leqhubu le tsamaeang, phepelo ea ho kenella e batla e le khanyetso e hloekileng, 'me e na le litšobotsi tsa Broadband. Ka lebaka la ts'ebetso ea eona e phahameng, e sebelisoa haholo ho aerospace, meteorology, positioning le relay puisano.

    lintlha tsa sehlahisoa

    Antenna ea helical / Spiral antenna ke mofuta o ikhethileng oa lenakana le ka fetisang le ho amohela mats'oao a polarized electromagnetic a potolohang sebakeng. Mofuta ona oa antenna hangata o sebelisoa liteisheneng tsa fatše bakeng sa likhokahano tsa sathelaete mme o entsoe ka litšepe tse nang le thepa e ntle ea ho tsamaisa. Hangata e fepeloa ka thapo ea coaxial, moo terata ea mantlha ea thapo ea coaxial e hokeloang pheletsong e 'ngoe ea terata ea spiral mme mokhanni oa kantle o hokahantsoe le letlooeng kapa poleiti ea tšepe e theiloeng fatše. Litšobotsi tsa mahlaseli a antenna ea spiral li amana haufi-ufi le selikalikoe sa spiral ea eona: ha selikalikoe se le senyenyane haholo ho feta bolelele ba maqhubu, tataiso e ka sehloohong ea mahlaseli ke perpendicular ho spiral axis; ha selikalikoe se le haufi le bolelele ba maqhubu, mahlaseli a matla ka ho fetisisa a hlaha ka lehlakoreng la axis ea spiral.

     

    Li-antenna tsa Helical / Spiral antennas li na le likarolo tse latelang tsa bohlokoa:

     

    1. Mahlaseli a tsepamisitsoe haholo-holo lehlakoreng la axis la antenna.
    2. E khona ho hlahisa maqhubu a circularly polarized, ka katleho ho hanyetsa liphello tsa litsela tse ngata le tšitiso ea matšoao.
    3. Kabo ea hajoale ho antenna e bonts'a sebopeho sa maqhubu a tsamaeang, se thusang ho fihlela phello e ts'oanang ea mahlaseli.
    4. Phetoho ea ho kenya letsoho e haufi le khanyetso e hloekileng, e nolofatsang moralo oa marang-rang a ts'oanang le ho ntlafatsa katleho.
    5. E na le litšobotsi tsa Broadband 'me e ka boloka ts'ebetso e sebetsang ea mahlaseli ka har'a mefuta e mengata ea maqhubu.

    Ka lebaka la ts'ebetso ea bona e bataletseng, ts'ebetso e ntlehali ea polarization, le bokhoni bo botle ba ho tima mollo le mahlakoreng, li-antenna tsa helical li 'nile tsa sebelisoa haholo mafapheng a mangata a kang aerospace, meteorology, positioning, le relay communications. Ka nts'etsopele e tsoelang pele ea theknoloji ea puisano e se nang mohala, ts'ebetso e phahameng ea motlakase ea li-antenna tsa helical e lebelletsoe ho ba fa sebaka se pharaletseng sa ts'ebeliso le nts'etsopele nakong e tlang.
