Maitiro ekugadzira Dielectric Sefa?

A Dielectric Filter is optical fiber iyo inosarudza kutumira imwe wavelength uye inoratidza vamwe zvichibva pakupindira mukati mechimiro. Inonziwo interference filter. Microwave dielectric mhedzisiro ceramics inovandudza saizi yemidziyo uye kurongedza density yemicrowave yakasanganiswa maseketi. Nechikonzero ichi, inoshandiswa zvakanyanya kune microwave mafirita uye edunhu mabhodhi mubhesi chiteshi chekufambisa nhare uye setiraiti yekutaurirana masisitimu kunyanya mu5G.
Yakagadzirwa nekukurumidza 5G tekinoroji ichaunza yakakura nzvimbo yemusika ku5G base station pamwe nedielectric sefa ye5g base station.

Design Principle

A symmetric modhi ye dielectric resonator sefa [1] inoongororwa pachishandiswa Scattering parameters module yeHFWorks kuti ione pass-bhendi yayo, kudzikisira mukati nekubuda mubhendi, uye kugovaniswa kwemunda wemagetsi kune dzakasiyana siyana. Mhedzisiro yacho inoratidza mutambo wakakwana neavo vakaunzwa mu [2]. Iwo matambo ane akarasika conductor, uye ane Teflon mukati chikamu. HF Works inopa mukana wekuronga akasiyana-siyana ekuScattering Parameters pa 2D uye Smith Chart zvirongwa. Kunze kwezvo, iyo munda wemagetsi unogona kuonwa muvector uye fringe 3D mapurani kune ese akadzidza ma frequency.

Simulation

Kutevedzera maitiro eiyi sefa (kupinza uye kudzoka kurasikirwa ...), isu tichagadzira Chidzidzo cheScattering Parameters, uye totsanangura iyo yakakodzera frequency renji panoshanda antenna (munyaya yedu zana mafrequency akagoverwa zvakafanana kubva ku4 GHz kuenda ku8 GHz. ).

Solids uye Zvishandiso

Mumufananidzo 1, takaratidza iyo discretized modhi ye dielectric redunhu sefa ine coaxial yekupinda uye inobuda couplers. Iwo maviri dielectric discs anoita seakabatanidzwa resonators zvekuti mudziyo wese unove wepamusoro-mhando bhendi sefa.

Mutoro/ Kudzora

Zviteshi zviviri zvinoshandiswa pamativi maviri ecoaxial couplers. Zviso zvepasi zvebhokisi remhepo zvinobatwa sePerfect Electric Boundaries. Chimiro chinobatsira iyo yakatwasuka symmetry ndege uye nekudaro, isu tinongoda kuenzanisira hafu imwe chete. Nekuda kweizvozvo, isu tinofanirwa kuzivisa kuti kune HFWorks simulator nekushandisa iyo PEMS muganhu mamiriro; ingave iri PECS kana PEMS, zvinoenderana nekutarisa kwemunda wemagetsi pedyo nemuganhu we symmetry. Kana tangential, saka iri PEMS; kana orthogonal saka iPECS.

Meshing

Iyo mesh inofanirwa kutariswa pane zviteshi uye zviso zvePEC. Meshing nzvimbo idzi dzinobatsira solver kukwenenzvera kwayo pamativi eddy, uye kutora iwo chaiwo mafomu mukufunga.

Results

Zvikamu zvakasiyana-siyana zve 3D uye 2D zviripo kuti zvishandise, zvichienderana nerudzi rwebasa uye kuti mushandisi anofarira paparameter ipi. Sezvatiri kubata nefirita simulation, kuronga iyo S21 parameter inonzwika senge intuitive basa.

Sezvambotaurwa pakutanga kwemushumo uyu, HFWorks inoronga macurves emagetsi paramita pane 2D zvirongwa pamwe neSmith Charts. Iyo yekupedzisira inonyanya kuenderana nenyaya dzekufananidza, uye inonyanya kukosha kana takatarisana nemasefa magadzirirwo. Tinocherechedza pano kuti tine mabhendi akapinza uye kuti tinosvika pakuzviparadzanisa nevamwe kunze kwebhendi.

Zvirongwa zve 3D zvezvidzidzo zvekuparadzira-zviyero zvinovhara zvakasiyana-siyana zvemiganhu: nhamba mbiri dzinotevera dzinoratidza kugoverwa kwemagetsi emagetsi maviri (imwe iri mukati mebhendi uye imwe iri kunze kwebhendi)

Iyo modhi inogona kutevedzerwa uchishandisa resonance solver yeHFWorks futi. Tinogona kuona akawanda modes sezvatinoda. Zviri nyore kutora chidzidzo chakadaro kubva kuS-Parameter simulated kudzidza: HFWorks inobvumira kudhonza uye kudonhedza erations kuti ikurumidze kuseta resonance simulation. Iyo resonance solver inofunga nezve modhi yeEM matrix uye inopa akasiyana Eigen mode mhinduro. Mhedzisiro yacho inonyatsoenderana nezvakabuda muzvidzidzo zvekare. Isu tinoratidza pano tafura yemhedzisiro:
