Nkhani - Kumvetsetsa mfundo za kapangidwe ndi mawonekedwe ogwirira ntchito a ma antenna a biconical

Antena ya Biconical ndi antenna yapadera ya wide-band yomwe kapangidwe kake kamakhala ndi ma cone awiri achitsulo ofanana omwe amalumikizidwa pansi ndipo amalumikizidwa ku gwero la chizindikiro kapena wolandila kudzera mu netiweki yochepetsera. Ma antenna a Biconical amagwiritsidwa ntchito kwambiri poyesa electromagnetic compatibility (EMC), kulumikizana opanda zingwe ndi machitidwe a radar. Mfundo yogwira ntchito ya antenna ya biconical ndikugwiritsa ntchito mawonekedwe owunikira ndi ma radiation a mafunde a electromagnetic pa ma conductor achitsulo. Pamene mafunde a electromagnetic alowa mu antenna ya biconical, amawonetsedwa kangapo pamwamba pa cone, ndikupanga mphamvu yofalitsa ma multipath. Kufalitsa ma multipath kumeneku kumapangitsa antenna kupanga mawonekedwe ofanana a radiation munjira ya radiation. Chinthu chachikulu cha ma antenna a biconical ndi magwiridwe awo a wide-band. Imatha kugwira ntchito pa ma frequency ambiri, nthawi zambiri imaphimba ma megahertz mazana angapo mpaka ma gigahertz angapo. Khalidweli limapangitsa ma antenna a biconical kugwiritsidwa ntchito kwambiri poyesa ndi kuyeza kulumikizana opanda zingwe kwa wide-band, komanso kuyesa kwa EMC kwa zida zosiyanasiyana zama frequency. Kuphatikiza apo, kapangidwe ka antenna ya biconical ndi kosavuta kupanga, kuyika ndi kugwiritsa ntchito. Komabe, ma antenna a biconical alinso ndi zoletsa zina. Choyamba, phindu la antenna ndi lochepa chifukwa cha magwiridwe ake a broadband. Kachiwiri, popeza kapangidwe ndi kupanga ma antenna kuyenera kuganizira kuchuluka kwa ma frequency ndi zofunikira zina, pakhoza kukhala mawonekedwe osiyanasiyana a antenna pa ma frequency band ena. Chifukwa chake, ndikofunikira kusankha antenna yoyenera ya biconical malinga ndi zofunikira zina zomwe zimagwiritsidwa ntchito. Kawirikawiri, antenna ya biconical ndi antenna yapadera yokhala ndi magwiridwe antchito a wide-band ndipo ndiyoyenera kulumikizana opanda zingwe kwa wide-band, kuyesa kwa EMC ndi kuyeza. Ili ndi ubwino wa kapangidwe kosavuta, kupanga kosavuta komanso kugwiritsa ntchito, koma chisamaliro chiyenera kuperekedwa pakusankha gain ndi mawonekedwe osiyanasiyana a frequency band.
