Keeb kwm thiab kev ua haujlwm ntawm cone horn antennas

Keeb kwm ntawm tapered horn antennas hnub rov qab mus rau thaum ntxov xyoo pua 20th. Thaum ntxov tapered horn antennas tau siv nyob rau hauv amplifiers thiab hais lus systems los txhim kho cov hluav taws xob ntawm lub teeb liab. Nrog rau txoj kev loj hlob ntawm kev sib txuas lus wireless, conical horn antennas tau maj mam siv hauv xov tooj cua thiab microwave teb. Nws qhov zoo hauv electromagnetic yoj hluav taws xob thiab txais tos ua rau nws yog ib qho tseem ceeb ntawm cov kav hlau txais xov. Tom qab xyoo 1950, nrog kev txhim kho sai ntawm microwave kev sib txuas lus thev naus laus zis, conical horn antennas pib siv dav hauv kev ua tub rog thiab pej xeem. Nws yog siv nyob rau hauv daim ntawv thov xws li radar systems, kev sib txuas lus systems, satellite kev sib txuas lus, xov tooj cua ntsuas thiab kav hlau txais xov arrays. Tus tsim thiab optimization ntawm tapered horn antennas kuj tau txais ib tug series ntawm kev tshawb fawb thiab kev txhim kho. Los ntawm thawj qhov kev tshuaj ntsuam theoretical mus rau kev qhia txog cov lej simulations thiab optimization algorithms, kev ua tau zoo ntawm tapered horn antennas txuas ntxiv txhim kho. Niaj hnub no, lub kav hlau txais xov tapered horn tau dhau los ua cov qauv kav hlau txais xov yooj yim thiab siv dav hauv kev sib txuas lus wireless thiab tshuab microwave.
Nws ua haujlwm los ntawm kev coj cov hluav taws xob tsis zoo los ntawm cov chaw nres nkoj me mus rau cov chaw nres nkoj loj kom ua tiav qhov nce siab thiab cov lus teb dav dav. Thaum lub electromagnetic nthwv dej nkag mus rau qhov chaw me me ntawm lub kav hlau txais xov tapered horn los ntawm cov kab sib kis (xws li coaxial cable), electromagnetic nthwv dej pib propagate raws ntawm cov qauv tapered. Raws li cov qauv conical maj mam nthuav dav, cov hluav taws xob hluav taws xob maj mam sib kis, ua rau thaj tsam loj dua. Qhov kev nthuav dav ntawm cov geometry no ua rau cov hluav taws xob hluav taws xob ua kom tawg tawm ntawm qhov chaw nres nkoj loj ntawm lub kav hlau txais xov horn tapered. Vim qhov tshwj xeeb ntawm cov qauv ntawm lub khob hliav qab, lub beam divergence ntawm electromagnetic nthwv dej nyob rau hauv cov hluav taws xob cheeb tsam yog me me, yog li muab ntau dua. Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub kav hlau txais xov conical hneev taw yog nyob ntawm qhov kev xav, refraction thiab diffraction ntawm electromagnetic tsis nyob rau hauv lub conical qauv. Cov txheej txheem no tso cai rau cov nthwv dej electromagnetic kom tsom mus thiab nthuav dav, tso cai rau lawv kom tawg tau zoo. Nyob rau hauv luv luv, lub hauv paus ntsiab lus ua hauj lwm ntawm ib tug conical horn kav hlau txais xov yog coj electromagnetic nthwv dej ntawm ib tug me me chaw nres nkoj mus rau ib tug loj chaw nres nkoj, ua tiav electromagnetic yoj hluav taws xob thiab siab dua los ntawm ib tug tshwj xeeb geometric qauv. Qhov no ua rau tapered horn antennas yog hom kav hlau txais xov tseem ceeb hauv kev sib txuas lus wireless thiab kev siv microwave.
