Mlongotiphindu ndi gawo lofunikira kwambiri pamakina olumikizirana opanda zingwe, chifukwa limatsimikizira kuthekera kwa mlongoti kuti atsogolere kapena kuyika mphamvu ya ma radio pafupipafupi mbali ina yake. Kuchulukitsa kwa tinyanga tating'onoting'ono kumawonjezera mphamvu yazizindikiro, kumakulitsa kulumikizana, ndikuwonjezera magwiridwe antchito onse. Nkhaniyi ikuyang'ana njira zothandiza zowonjezerera kupindula kwa tinyanga, kuyang'ana kwambiri pamipangidwe, njira zokometsera, ndi matekinoloje apamwamba.
1. Konzani Kapangidwe ka Antenna
Kupindula kwa mlongoti kumagwirizana kwambiri ndi mapangidwe ake. Imodzi mwa njira zothandiza kwambiri zopezera phindu ndi kugwiritsa ntchito mlongoti wolunjika, monga Yagi-Uda, parabolic reflector, kapena patch antenna, yomwe imayang'ana mphamvu kumalo enaake m'malo mowunikira mofanana kumbali zonse. Mwachitsanzo, tinyanga tating'onoting'ono timapeza phindu lalikulu poyang'ana ma siginecha pamalo okhazikika, zomwe zimawapangitsa kukhala oyenera kulumikizana ndi mtunda wautali.
2. Wonjezerani Kukula kwa Mlongoti
Kupindula kwa mlongoti kumayenderana ndi kabowo kake kogwira mtima, komwe kumagwirizana mwachindunji ndi kukula kwake. Tinyanga zazikulu zimatha kugwira kapena kutulutsa mphamvu zambiri, zomwe zimapangitsa kupindula kwakukulu. Mwachitsanzo, tinyanga ta mbale zokhala ndi mainchesi akulu zimapereka phindu lalikulu chifukwa cha kuchuluka kwawo. Komabe, njira imeneyi ndi yochepa ndi zopinga zothandiza monga malo ndi mtengo.
3. Gwiritsani ntchitoZithunzi za Antenna
Minyanga ya tinyanga imakhala ndi tinyanga tambirimbiri tomwe timasanjidwa mwadongosolo linalake. Mwa kuphatikiza zizindikiro kuchokera kuzinthu izi, mndandandawu ukhoza kupindula kwambiri ndi kuwongolera. Mwachitsanzo, tinyanga tating'onoting'ono, timagwiritsa ntchito njira zosinthira magawo kuti ziwongolere mtengowo pakompyuta, zomwe zimapatsa kupindula kwakukulu komanso kusinthasintha kolowera.

4. Kupititsa patsogolo Kudya Mwachangu
Dongosolo la chakudya, lomwe limasamutsa mphamvu pakati pa chotumizira/cholandira ndi mlongoti, limagwira ntchito yofunika kwambiri pozindikira phindu. Kugwiritsa ntchito zinthu zotsika pang'ono komanso kukhathamiritsa ma network a chakudya kumatha kuchepetsa kutayika kwa mphamvu ndikuwongolera magwiridwe antchito. Mwachitsanzo, zingwe za coaxial zokhala ndi ma attenuation ochepa kapena ma waveguide feed zitha kupititsa patsogolo magwiridwe antchito.
5. Chepetsani Kutayika
Kutayika mu dongosolo la antenna, monga kutayika kotsutsa, kutayika kwa dielectric, ndi kusagwirizana kwa impedance, kungachepetse phindu. Kugwiritsa ntchito zida zowongolera kwambiri (mwachitsanzo, mkuwa kapena aluminiyamu) pamapangidwe a tinyanga ndi zida zotsika pang'ono za dielectric pamagawo ang'onoang'ono zimatha kuchepetsa kutayika kumeneku. Kuphatikiza apo, kuwonetsetsa kuti kulumikizana koyenera pakati pa mlongoti ndi chingwe chotumizira kumakulitsa kusamutsa kwamagetsi ndikuwonjezera phindu.
6. Gwirani Ntchito Zowunikira ndi Otsogolera
Mu tinyanga zolunjika monga ma antennas a Yagi-Uda, zowunikira ndi owongolera zimagwiritsidwa ntchito kuti apindule. Zowunikira zimayikidwa kuseri kwa chinthu chowunikira kuti chiwongolere mphamvu kutsogolo, pomwe owongolera amakhala kutsogolo kuti ayang'ane mtengowo. Kuyang'ana moyenerera ndi kukula kwa zinthu izi kungathandize kwambiri kupindula ndi kuwongolera.
Mapeto
Kuchulukitsa kwa tinyanga tating'ono kumaphatikizapo kuphatikizika kwa mapangidwe osamalitsa, kusankha zinthu, ndi njira zapamwamba. Mwa kukhathamiritsa mawonekedwe a mlongoti, kuchepetsa kutayika, komanso matekinoloje owonjezera ngati milongosoledwe ya mlongoti ndi kuwundana, ndizotheka kukwaniritsa bwino pakupindula ndi magwiridwe antchito onse. Zowonjezera izi ndizofunikira pazogwiritsa ntchito kuyambira kulumikizana opanda zingwe kupita ku makina a radar ndi satana.
Kuti mudziwe zambiri za antennas, chonde pitani:
