Hoʻomaka ka mōʻaukala o nā antenna horn i ka makahiki 1897, i ka wā i alakaʻi ai ka mea noiʻi lekiō ʻo Jagadish Chandra Bose i nā hoʻolālā hoʻokolohua paionia me ka hoʻohana ʻana i nā microwave.Ma hope mai, ua haku ʻo GC Southworth lāua ʻo Wilmer Barrow i ke ʻano o ka antenna pū kani hou i ka makahiki 1938.Mai ia manawa, ua aʻo mau ʻia nā hoʻolālā antenna horn e wehewehe i kā lākou mau hiʻohiʻona radiation a me nā noi i nā ʻano like ʻole.Ua kaulana loa kēia mau antenna ma ke kahua o ka hoʻouna nalu a me nā microwaves, no laila ua kapa pinepine ʻia lākounā antenna microwave.No laila, e ʻimi kēia ʻatikala pehea e hana ai nā antenna horn a me kā lākou noi ma nā ʻano like ʻole.
He aha ke ʻano o ka antenna pu?
A antenna kiwiHe antenna aperture i hoʻolālā kūikawā ʻia no nā alapine microwave i hoʻonui ʻia a i ʻole ke ʻano o ka pū.Hāʻawi kēia ʻano i ka antenna i ka kuhikuhi ʻoi aku, e ʻae i ka hōʻailona emited e maʻalahi i ka hoʻouna ʻana i nā mamao lōʻihi.Hoʻohana nui ʻia nā antenna Horn i nā alapine microwave, no laila ʻo kā lākou alapine pinepine ʻo UHF a i ʻole EHF.
RFMISO horn antenna RM-CDPHA618-20 (6-18GHz)
Hoʻohana ʻia kēia mau antenna e like me nā kiwi hānai no nā antenna nui e like me ka parabolic a me nā antenna kuhikuhi.ʻO kā lākou mau mea maikaʻi ʻo ia ka maʻalahi o ka hoʻolālā a me ka hoʻoponopono ʻana, haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, haʻahaʻa pololei, a me ka bandwidth ākea.
Hoʻolālā a me ka hana ʻana o ka antenna Horn
Hiki ke hoʻokō ʻia nā hoʻolālā antenna Horn me ka hoʻohana ʻana i nā alakaʻi hawewe kani no ka hoʻouna ʻana a me ka loaʻa ʻana o nā hōʻailona microwave frequency radio.ʻO ka maʻamau, hoʻohana pū ʻia lākou me nā hānai nalu a me nā nalu lekiō pololei e hana i nā kaola haiki.Hiki i ka ʻāpana flared ke hele mai i nā ʻano like ʻole, e like me ka square, conical, a i ʻole rectangular.No ka hōʻoia ʻana i ka hana kūpono, pono e liʻiliʻi ka nui o ka antenna.Inā nui loa ka nalu a i ʻole ka liʻiliʻi o ka pū, ʻaʻole e hana pono ka antenna.
Kiʻi kiʻi kiʻi kiʻi antenna
I loko o kahi antenna pū, ua hoʻomālamalama ʻia kahi ʻāpana o ka ikehu hanana mai ka puka o ka nalu, aʻo ke koena o ka ikehu e ʻike ʻia mai ka puka like no ka mea ua hāmama ka puka komo, e hopena i kahi hoʻokūkū impedance maikaʻi ʻole ma waena o ke ākea a me ka. alakaʻi nalu.Eia kekahi, ma nā ʻaoʻao o ke alakaʻi hawewe, pili ka diffraction i ka mana radiative o ke alakaʻi nalu.
I mea e lanakila ai i nā hemahema o ke alakaʻi nalu, ua hoʻolālā ʻia ka wehe ʻana i ke ʻano o kahi pu electromagnetic.Hāʻawi kēia i kahi hoʻololi maʻalahi ma waena o ka lewa a me ke alakaʻi nalu, e hāʻawi ana i ka kuhikuhi pono no nā hawewe lekiō.
Ma ka hoʻololi ʻana i ke alakaʻi nalu e like me ke ʻano o ka pū, ua hoʻopau ʻia ka discontinuity a me ka 377 ohm impedance ma waena o ke ākea a me ka hawewe.Hoʻonui kēia i ka kuhikuhi a me ka loaʻa ʻana o ka antenna transmit ma ka hōʻemi ʻana i ka diffraction ma nā kihi e hāʻawi i ka ikehu hanana i hoʻokuʻu ʻia i ka ʻaoʻao i mua.
Penei ke ʻano o ka hana ʻana o ka antenna pu: Ke hoʻohauʻoli kekahi ʻaoʻao o ke alakaʻi nalu, hoʻopuka ʻia kahi māla magnetic.I ka hihia o ka hoʻolaha ʻana o ka nalu, hiki ke hoʻomalu ʻia ke kahua hoʻolaha ma o nā paia alakaʻi nalu i ʻole e hoʻolaha ʻia ke kahua ma ke ʻano spherical akā ma ke ʻano e like me ka hoʻolaha ākea manuahi.Ke hiki aku ke kahua hele i ka hopena alakaʻi nalu, hoʻolaha ʻo ia ma ke ʻano like me ka lewa kaʻawale, no laila e loaʻa kahi alo nalu spherical ma ka hopena hawewe.
