Dọpụl a kpọchiri akpọchi bụ antenna nke nwere ndị na-eduzi abụọ yiri ibe ha jikọtara na nsọtụ abụọ ahụ, na-emepụta nhazi dị ka loop mechiri emechi, ebe nri dị n'etiti. Ogologo antenna ahụ dum bụ ọkara ogologo ebili mmiri, nke mere e ji akpọkwa ya antenna dipole a kpọchiri akpọchi nke ọkara ebili mmiri.
Oke ugboro ole
Antenna dipole a kpọchiri akpọchi nke ọkara-wave na-arụ ọrụ n'ofe ugboro ole dị ihe dịka 3 kHz ruo 300 GHz, a na-ejikwa ya eme ihe karịsịa na ndị nnata telivishọn.
Usoro na Ụkpụrụ Ọrụ nke Dipole a kpọchiri akpọchi nke ọkara-wave
A na-ejikarị ụdị antenna a eme ihe na antenna array iji mee ka mgbochi ntinye dịkwuo elu na ebe nri. Ihe a na-ejikarị eme ihe bụ antenna Yagi. Foto dị n'okpuru na-egosi antenna dipole a kpọchiri akpọchi nke ọkara-ebili.
Ma e jiri ya tụnyere eriri dipole nkịtị, eriri dipole a kpọchiri akpọchi na-ewebata onye na-eduzi parallel ọzọ (ya bụ, waya ma ọ bụ mkpanaka ọzọ). Site n'itinye ọtụtụ ndị na-eduzi parallel n'akụkụ ibe ha na mkpuchi n'etiti ha, enwere ike ịmepụta eriri ụdị array.
Foto dị n'okpuru na-egosi ụkpụrụ ọrụ nke antenna dipole a kpọchiri akpọchi ọkara-ebili mgbe obi dị ya ụtọ.
Ọ bụrụ na dayameta nke onye nduzi bụ isi yiri nke onye nduzi yiri nke dị na dipole a kpọchiri akpọchi, mgbochi isi nri nke antenna na-abawanye site na ihe dị ka anọ (square nke abụọ). Mmụba a na mgbochi nri bụ isi ihe mere e ji eji antenna dipole a kpọchiri akpọchi eme ihe nke ukwuu. N'ihi owuwu ya nke nwere ụzọ abụọ, mgbochi ya na-adịkarị ihe dị ka 300 Ω.
Ụdị radieshọn
Usoro radieshọn nke dipole a kpọchiri akpọchi nke ọkara-ebili yiri nke mpi dipole ọkara-ebili. Foto dị n'okpuru na-egosi usoro radieshọn omnidirectional nke mpi dipole a kpọchiri akpọchi nke ọkara-ebili.
A na-eji antenna dipole a kpọchiri akpọchi nke ọkara-ebili n'ọrụ ebe achọrọ nnyefe ike kachasị elu na ebe achọrọ mgbochi dị elu.
Dọpụl a a kpọchiri akpọchi bụ isi ihe na-enwu enwu n'ime antenna Yagi. Foto dị n'okpuru na-egosi antenna Yagi (nke a ga-atụle nke ọma ma emechaa). N'ime antenna a, a na-ejikọ ebe nri na dipole a kpọchiri akpọchi dị ka ihe dị mkpa. N'ime iri afọ ole na ole gara aga, a na-eji ụdị antenna a eme ihe nke ukwuu maka nnabata telivishọn.
Uru ndị a bụ uru nke eriri dipole a kpọchiri akpọchi nke ọkara-ebili.
1. Na-enweta akara ngosi ziri ezi.
2. Na-ejide akara achọrọ site na otu eriri ugboro ugboro kpọmkwem na-enweghị mfu nke mma.
3. Oke a kpọchiri akpọchi na-eme ka ike mgbaama dịkwuo elu.
