Indlela Yokuklama Isihlungi Se-Dielectric?

I-Dielectric Filter iyifayibha ebonakalayo edlulisa i-wavelength eyodwa ngokukhetha futhi ibonise ezinye ngokusekelwe Ekuphazameni ngaphakathi kwesakhiwo. Futhi kuthiwa isihlungi sokuphazanyiswa. I-Microwave dielectric effect Ceramics ithuthukisa usayizi wamadivayisi kanye nokuminyana kokupakishwa kwamasekhethi ahlanganisiwe we-microwave. Ngalesi sizathu, isetshenziswa kakhulu izihlungi ze-microwave namabhodi wesekethe esiteshini esiyisisekelo sokuxhumana kwamaselula kanye nezinhlelo zokuxhumana ngesathelayithi ikakhulukazi ku-5G.
Ubuchwepheshe obuthuthuke ngokushesha be-5G buzoletha indawo yemakethe enkulu esiteshini sesisekelo se-5G kanye nesihlungi se-dielectric sesiteshi esingu-5g.

Isimiso Sokuklama

Imodeli elinganayo yesihlungi se-dielectric resonator [1] ihlaziywa kusetshenziswa imojuli yepharamitha ye-Scattering ye-HFWorks ukuze kutholwe ibhendi yayo yokudlula, ukuncipha kokungena nokuphuma kwebhendi, kanye nokusatshalaliswa kwenkundla kagesi kumafrikhwensi ahlukahlukene. Umphumela ukhombisa ukufana okuhle kakhulu nalezo ezethulwe ku-[2]. Izintambo zine-conductor elahlekile, futhi zinengxenye ye-Teflon ngaphakathi. I-HF Works inikeza ithuba lokuhlela amapharamitha e-Scattering ehlukahlukene ku-2D kanye ne-Smith Chart iziza. Ngaphandle kwalokho, indawo kagesi ingabonwa ku-vector kanye neziqephu ze-3D zazo zonke iziza ezifundiwe.

Ukulingisa

Ukuze silingise ukuziphatha kwalesi sihlungi (ukufakwa nokubuyisela ukulahlekelwa...), sizodala ucwaningo lwe-Scattering Parameters, futhi sicacise ibanga elifanele lefrikhwensi lapho i-antenna isebenza khona (kithina amafrikhwensi angu-100 asakazwa ngokufanayo ukusuka ku-4 GHz ukuya ku-8 GHz. ).

Okuqinile Nezinto Zokusebenza

Emfanekisweni 1, sibonise imodeli ecashile yesihlungi sesekethe ye-dielectric enokufakwa kwe-coaxial nokukhipha ama-couplers. Amadiski e-dielectric amabili asebenza njengama-resonator ahlanganisiwe kangangokuthi yonke idivayisi iba isihlungi sekhwalithi ephezulu ye-bandpass.

Umthwalo/ Ukuvinjelwa

Izimbobo ezimbili zisetshenziswa emaceleni ama-coaxial couplers amabili. Ubuso obuphansi bebhokisi lomoya buphathwa njenge-Perfect Electric Boundaries. Isakhiwo senza inzuzo ngendiza ye-symmetry evundlile ngakho-ke, sidinga ukumodela ingxenye eyodwa kuphela. Ngakho-ke, kufanele simemezele lokho kusifanisi se-HFWorks ngokusebenzisa isimo somngcele we-PEMS; kungakhathaliseki ukuthi i-PECS noma i-PEMS, incike ekuqondisweni kwenkambu kagesi eduze nomngcele wokulinganisa. Uma i-tangential, kusho ukuthi yi-PEMS; uma i-orthogonal kusho ukuthi i-PECS.

I-Meshing

I-mesh kufanele igxile emachwebeni nasebusweni be-PEC. Ukuhlanganisa lezi zindawo kusiza isixazululi sicwenge ukunemba kwaso ezingxenyeni ze-eddy, futhi sicabangele amafomu azo athile.

Imiphumela

Iziza ezihlukahlukene ze-3D ne-2D ziyatholakala ukuze zisetshenziswe, kuye ngohlobo lomsebenzi kanye nokuthi iyiphi ipharamitha umsebenzisi ayithakaselayo. Njengoba sibhekene nokulingiswa kwesihlungi, ukuhlela ipharamitha ye-S21 kuzwakala njengomsebenzi onembile.

Njengoba kushiwo ekuqaleni kwalo mbiko, i-HFWorks yenza amajika amajika amapharamitha kagesi ezizindeni ze-2D kanye nakuSmith Charts. Eyakamuva ifaneleka kakhulu ezinkingeni ezifanayo, futhi ifaneleka kakhulu lapho sibhekana nemiklamo yokuhlunga. Siyaqaphela lapha ukuthi sinamabhendi okudlula abukhali nokuthi sifinyelela ukuhlukaniswa okukhulu ngaphandle kwebhendi.

Iziza ze-3D zezifundo zamapharamitha wokuhlakazeka zihlanganisa ububanzi bepharamitha: izibalo ezimbili ezilandelayo zibonisa ukusatshalaliswa kwenkundla kagesi kumafrikhwensi amabili (eyodwa ingaphakathi kwebhendi kanti enye ingaphandle kwebhendi)

Imodeli ingalingiswa kusetshenziswa isixazululi se-resonance se-HFWorks futhi. Singathola izindlela eziningi ngendlela esifisa ngayo. Kulula ukuthola ucwaningo olunjalo ocwaningweni olulingiswayo lwe-S-Parameter : I-HFWorks ivumela izikhathi zokudonsa nokwehlisa ukuze kumiswe ngokushesha ukulingiswa kwe-resonance. Isixazululi se-resonance sicabangela i-matrix ye-EM yemodeli futhi ilethe izixazululo ezihlukahlukene zemodi ye-Eigen. Imiphumela ihambisana kahle kakhulu nemiphumela yezifundo zangaphambili. Sibonisa lapha ithebula lemiphumela :
