Sesefa sa Dielectric ke fiber ea optical e fetisang bolelele bo le bong 'me e bonahatsa tse ling ho latela Tšitiso ka hare ho sebopeho. E boetse e bitsoa "interference filter". Li-ceramics tsa phello ea dielectric tsa microwave li ntlafatsa boholo ba lisebelisoa le bongata ba liphutheloana tsa li-circuits tse kopaneng tsa microwave. Ka lebaka lena, e sebelisoa haholo bakeng sa li-filters tsa microwave le liboto tsa potoloho setsing sa motheo sa puisano ea mehala le mekhoa ea puisano ea sathelaete haholo-holo ho 5G.
Theknoloji ea 5G e tsoetseng pele ka potlako e tla tlisa sebaka se seholo sa 'maraka ho setsi sa motheo sa 5G hammoho le filthara ea dielectric bakeng sa 5g base station.
Moralo Molao-motheo
Moetso oa symmetric oa filthara ea dielectric resonator [1] e sekasekoa ho sebelisoa module ea Scattering parameters ea HFWorks ho fumana hore na e feta sehlopha sefe, ho fokotseha hoa le ho tsoa ho sehlopha, le phepelo ea masimo a motlakase bakeng sa maqhubu a fapaneng. Sephetho se bonts'a papali e phethahetseng le e hlahisitsoeng ho [2]. Lithapo li na le conductor e lahlehileng, 'me li na le Teflon ka hare ho karolo. HF Works e fana ka monyetla oa ho rera li-Parameters tse fapaneng tsa Scattering ho 2D le Smith Chart plots. Ntle le moo, lebala la motlakase le ka bonoa ka har'a vector le fringe 3D plots bakeng sa maqhubu ohle a ithutoang.
Ketsiso
Ho etsisa boits'oaro ba sefa sena (ho kenya le ho khutlisa tahlehelo ...), re tla theha boithuto ba Scattering Parameters, mme re hlakise mefuta e nepahetseng ea maqhubu ao lenakana le sebetsang ho lona (tabeng ea rona, maqhubu a 100 a ajoa ka mokhoa o ts'oanang ho tloha 4 GHz ho ea ho 8 GHz. ).
Matla le Lisebelisoa
Setšoantšong sa 1, re bonts'itse mohlala oa discretized oa filthara ea potoloho ea dielectric e nang le coaxial input le output couplers. Li-dielectric discs tse peli li sebetsa joalo ka li-resonator tse kopantsoeng hoo sesebelisoa sohle se fetohang mochini oa boleng bo holimo oa bandpass.
Mojaro/ Ho thiba
Likou tse peli li sebelisoa ka mahlakoreng a li-coaxial couplers tse peli. Lifahleho tse ka tlaase tsa lebokose la moea li tšoaroa e le Meeli e Phethahetseng ea Motlakase. Sebopeho se ruisa sefofane se otlolohileng sa symmetry, ka hona, re hloka feela ho etsa mohlala oa halofo e le 'ngoe. Ka lebaka leo, re lokela ho phatlalatsa hore ho simulator ea HFWorks ka ho sebelisa boemo ba moeli oa PEMS; ho sa tsotellehe hore na ke PECS kapa PEMS, ho itšetlehile ka ho shebana le sebaka sa motlakase haufi le moeli oa symmetry. Haeba tangential, joale ke PEMS; haeba e le orthogonal joale ke PECS.
Meshing
Mesh e tlameha ho tsepamisoa haholo likoung le lifahlehong tsa PEC. Ho kopanya libaka tsena ho thusa solver ho ntlafatsa ho nepahala ha eona likarolong tsa eddy, le ho ela hloko mefuta ea tsona.

Joalo ka ha ho boletsoe qalong ea tlaleho ena, HFWorks e etsa li-curve bakeng sa liparamente tsa motlakase ho lipolanete tsa 2D hammoho le ho Smith Charts. Ea morao-rao e loketse haholoanyane litaba tse tsamaellanang, 'me e sebetsa haholoanyane ha re sebetsana le meralo ea li-filters. Re hlokomela mona hore re na le li-pass-band tse bohale le hore re fihla ho itšehla thajana ka ntle ho sehlopha.
Merero ea 3D bakeng sa lithuto tsa li-parameters tsa ho hasanya li akaretsa mefuta e mengata e fapaneng: lipalo tse peli tse latelang li bontša kabo ea matla a motlakase bakeng sa maqhubu a mabeli (e 'ngoe e ka hare ho sehlopha' me e 'ngoe e ka ntle ho sehlopha)
Moetso ona o ka etsisoa ho sebelisoa resonance solver ea HFWorks le eona. Re ka bona mefuta e mengata kamoo re batlang. Ho bonolo ho fumana thuto e joalo ho tsoa thutong e qapiloeng ea S-Parameter : HFWorks e lumella ho hula le ho theola likhahla ho theha ketsiso ea resonance kapele.
