Mlongoti ndi mtundu wa zida wamba, chimagwiritsidwa ntchito pa wailesi, televizioni, wailesi kulankhulana, radar, navigation, countermeasures pakompyuta, kuzindikira kutali, zakuthambo wailesi ndi zina.Mlongoti ndi chipangizo chomwe chimatha kuwunikira bwino mafunde amagetsi kupita kudera linalake lamlengalenga kapena kulandira mafunde amagetsi kuchokera kudera linalake lamlengalenga.Chida chilichonse chomwe chimatumiza ma siginecha kudzera pa mafunde a electromagnetic chimayenera kunyamula mlongoti.
Timapeza m'moyo wathu watsiku ndi tsiku kuti kutembenuza kapena kutambasula mlongoti wa wailesi kapena wailesi yakanema, mwadala kapena mosadziwa, kungakhudze khalidwe la chizindikiro.M'malo mwake, imasintha magawo a antenna ndipo imakhudza kulandila kwa mafunde amagetsi.Kutumiza ndi kulandira kwa mlongoti kumagwirizana kwambiri ndi magawo a mlongoti.Apa tikuwonetsa magawo oyambira a mlongoti.
1. Ntchito pafupipafupi gulu
Mlongoti nthawi zonse umagwira ntchito mosiyanasiyana (m'lifupi mwa bandi), zomwe zimatengera zofunikira za index.Ma frequency osiyanasiyana omwe amakwaniritsa zofunikira za index ndi ma frequency ogwiritsira ntchito antenna.Ma frequency band omwe amagwiritsidwa ntchito ndi ogwiritsa ntchito amasiyana ndi machitidwe osiyanasiyana opanda zingwe.Chifukwa chake, ma antennas okhala ndi ma frequency oyenerera ayenera kusankhidwa.
2. Kupindula
Kupeza kwa mlongoti kumatanthawuza kuchuluka kwa kachulukidwe kamphamvu ka siginecha yopangidwa ndi mlongoti weniweni komanso gawo loyenera la radiation pamalo omwewo mumlengalenga pansi pa mphamvu yolowera yofanana.Kupindula kumagwirizana kwambiri ndi chitsanzo cha antenna.Kuchepa kwa lobe yayikulu ndi kuchepera kwa sidelobe, kumapangitsanso phindu.Kupeza kwa mlongoti ndi muyeso wa kuthekera kwa mlongoti kutulutsa mafunde a electromagnetic mbali ina yake.Tiyenera kuzindikira kuti mlongoti wokhawokhawokhawokhawokhawokhawokhawokhawokhawokhawokhawokhawokhawokhawokhawokhawokhawokhawokhawokhawokhawokhawokhawokhawokhawokhawokhawokhawokha kudzera mu kuphatikiza kwa ma vibrators a mlongoti ndikusintha njira yodyetsera.
3. Bandwidth
Bandwidth ndi gawo lina lofunikira la antenna.Bandwidth imafotokoza kuchuluka kwa ma frequency omwe mlongoti umatha kuwunikira kapena kulandira mphamvu moyenera.Tinyanga zokhala ndi bandwidth yaying'ono kwambiri sizingagwiritsidwe ntchito pamapulogalamu a Broadband.
M'moyo weniweni, kuti akwaniritse zosowa zosiyanasiyana, akatswiri apanga tinyanga tambirimbiri.Chodziwika kwambiri ndi Mlongoti wautali uwu, wotchedwa Vertical monopole antenna, kapena GP mlongoti, womwe umapezeka pazida zam'manja.
Uwu ndi mlongoti wotchuka wa Yagi, wopangidwa ndi mayunitsi angapo, ndipo uli ndi mayendedwe amphamvu, maupangiri ochulukirapo, owongolera kwambiri, amapindula kwambiri.
Nthawi zambiri timawona ngati mlongoti mbale padenga la nyumba.Ndi mlongoti wolunjika kwambiri womwe umagwiritsidwa ntchito makamaka pakulankhulana kwakutali.Ili ndi m'lifupi mwake ndi yopapatiza kwambiri komanso mtengo wopindulitsa kwambiri, womwe ungatchulidwenso kuti mlongoti wowongolera kwambiri.
Maonekedwe a tinyanga ndi odabwitsa,
Inu nokha mungaganizire,
Sindingathe kuchita popanda MHZ-TD
