Pakupanga ma antenna a microwave, kukwera bwino kwa ma antenna kuyenera kulinganiza magwiridwe antchito ndi magwiridwe antchito. Ngakhale kukwera kwakukulu kumatha kupititsa patsogolo mphamvu ya ma siginolo, kumabweretsa mavuto monga kukula kwakukulu, zovuta zotaya kutentha komanso kukwera mtengo. Izi ndi mfundo zazikulu zofunika kuziganizira:
1. Kufananiza phindu ndi kugwiritsa ntchito
Siteshoni ya 5G base (millimeter wave AAU):24-28dBi, imafunachotsukira vacuummbale yoziziritsira madzi kuti iwonetsetse kuti ikugwira ntchito kwa nthawi yayitali.
Kulankhulana kwa satellite (Ka band):40-45dBi, kudalira kuziziritsa kwa madzi a mkuwa wobisika kuti athetse vuto la kutaya kutentha kwa ma antenna akuluakulu otseguka.
Nkhondo yamagetsi/radar:20-30dBi, pogwiritsa ntchito kuziziritsa kwa madzi osakaniza ndi stir friction welding kuti agwirizane ndi kutentha kwakukulu.
Kuyesa kwa EMC:10-15dBi, chotenthetsera chotenthetsera chachizolowezi chingakwaniritse zosowa.
Antena ya Cassegrain (40dBi)
Antena ya Horn Yozungulira Yokhala ndi Polarized (20dBi)
2. Zolepheretsa zauinjiniya za phindu lalikulu
Botolo la kutayira kutentha: Ma antenna opitilira 25dBi nthawi zambiri amafunikira kuziziritsa kwamadzimadzi (monga vacuum brazing kapena stir friction welding water cooling plate), apo ayi mphamvu yamagetsi imakhala yochepa.
Zoletsa kukula: Ma antenna opitilira 30dBi amatha kupitirira mita imodzi mu gulu la Ka, ndipo kapangidwe kake kayenera kukonzedwa bwino.
Zinthu Zokhudza Mtengo: Pa kuwonjezeka kulikonse kwa 3dB, mtengo wa makina oziziritsira ukhoza kuwonjezeka ndi 20%-30%.
Antena ya Planar (30dBi)
Antena ya Horn Yozungulira Yozungulira (10dBi)
3. Malangizo okonza zinthu
Ikani patsogolo zofunikira zofananira ndi mapulogalamu ndipo pewani kufunafuna phindu lalikulu.
Njira yoziziritsira imatsimikiza mphamvu yamagetsi, ndipo ma antenna okwera kwambiri ayenera kukhala ndi kuziziritsa kogwira mtima (monga kuziziritsa kwamadzimadzi).
Kulinganiza kuchuluka kwa ma bandwidth ndi phindu. Makina a Narrowband amatha kutsata phindu lalikulu, ndipo makina a broadband ayenera kupanga mapangano oyenera.
Kutsiliza: Kupeza bwino kumadalira kugwiritsa ntchito kwake, nthawi zambiri pakati pa 20-35dBi, ndipo kuyenera kuphatikizidwa ndi ukadaulo wapamwamba woziziritsira (monga vacuum brazing kapena stir friction welding water cooling) kuti zitsimikizire kuti ntchito yake ndi yodalirika.
Kuti mudziwe zambiri zokhudza ma antenna, chonde pitani ku:
