Polarization ya Antena: Polarization ya Antena ni iki kandi impamvu ari ingenzi
Abahanga mu by'ikoranabuhanga bazi ko antene zohereza kandi zikakira ibimenyetso mu buryo bw'imiraba y'ingufu za electromagnetic (EM) zisobanurwa n'ibigereranyo bya Maxwell. Kimwe n'ingingo nyinshi, ibi bigereranyo, hamwe n'uburyo electromagnetism ikwirakwira, bishobora kwigwa mu buryo butandukanye...Soma byinshi -
Ihame ry'imikorere n'ikoreshwa rya antene y'ihoni
Amateka ya antene z'amahoni atangira mu 1897, ubwo umushakashatsi wa radiyo Jagadish Chandra Bose yakoraga ibishushanyo mbonera by'igerageza akoresheje mikoroonde. Nyuma, GC Southworth na Wilmer Barrow bavumbuye imiterere ya antene igezweho y'amahoni mu 1938. Kuva ...Soma byinshi -
Antene y'ihoni ni iki? Ni ayahe mahame y'ingenzi n'akamaro kayo?
Antene y'ihembe ni antene yo hejuru, antene ya mikoroonde ifite igice cy'uruziga cyangwa cy'urukiramende aho igice cy'umuyoboro w'amazi gifunguka buhoro buhoro. Ni bwo bwoko bwa antene ya mikoroonde ikoreshwa cyane. Imirasire yayo iterwa n'ingano y'umunwa n'uburyo...Soma byinshi -
Ese uzi itandukaniro riri hagati y'udukingirizo tw'amajwi tworoshye n'udukingirizo tw'amajwi dukomeye?
Soft waveguide ni umurongo utuma ibikoresho bya microwave bihagarara neza n'ibikoresho byo kugaburira. Urukuta rw'imbere rw'umuyoboro woroshye rufite imiterere imeze nk'iy'ibumba, yoroshye cyane kandi ishobora kwihanganira kunama, kwaguka no gukandamizwa bigoye. Kubwibyo, ni ...Soma byinshi -
Antene zikunze gukoreshwa | Intangiriro ku bwoko butandatu butandukanye bwa antene z'amahoni
Antene y'ihembe ni imwe muri antene zikoreshwa cyane zifite imiterere yoroshye, ingano nini y'amajwi, ubushobozi bunini bw'ingufu n'ubushobozi bwo kwiyongera cyane. Antene z'ihembe zikunze gukoreshwa nk'antene zo kohereza amakuru mu bumenyi bw'ikirere bwa radiyo nini, gukurikirana ibyogajuru, na antene z'itumanaho. Uretse s...Soma byinshi -
