Momwe Mungapangire Sefa ya Dielectric?

Sefa ya Dielectric ndi chingwe cha kuwala chomwe chimasamutsa kutalika kwa mawonekedwe amodzi ndikuwonetsa ena kutengera Kusokoneza mkati mwa kapangidwe kake. Amatchedwanso interference filter. Microwave dielectric zotsatira za ceramics zimathandizira kukula kwa zida ndi kachulukidwe ka mabwalo ophatikizika a microwave. Pazifukwa izi, amagwiritsidwa ntchito kwambiri pazosefera za ma microwave ndi ma board ozungulira pamalo oyambira kulumikizana ndi mafoni ndi njira zoyankhulirana za satellite makamaka mu 5G.
Ukadaulo wopangidwa mwachangu wa 5G ubweretsa malo amsika ochulukirapo ku 5G base station komanso fyuluta ya dielectric ya 5g base station.

Mfundo Yopanga

Chitsanzo chofananira cha fyuluta ya dielectric resonator [1] imawunikidwa pogwiritsa ntchito Scattering parameters module ya HFWorks kuti idziwe pass-band yake, kutsekemera mkati ndi kunja kwa bandi, ndi magawo a magetsi a magetsi osiyanasiyana. Zotsatira zikuwonetsa kufanana koyenera ndi zomwe zawonetsedwa mu [2]. Zingwe zimakhala ndi kondakitala wotayika, ndipo zimakhala ndi Teflon mkati mwa gawo. HF Works imapereka mwayi wokonza magawo osiyanasiyana a Scattering pa 2D ndi Smith Chart ziwembu. Kupatula apo, gawo lamagetsi limatha kuwonedwa mu vector ndi fringe 3D ziwembu pama frequency onse ophunziridwa.

Kuyerekezera

Kutengera khalidwe la fyulutayi (kulowetsa ndi kubwereranso kutayika ...), tidzapanga kafukufuku wa Scattering Parameters, ndikulongosola maulendo oyenera omwe mlongoti umagwirira ntchito (kwa ife ma frequency 100 amagawidwa mofanana kuchokera ku 4 GHz kufika ku 8 GHz. ).

Zolimba ndi Zida

Pachithunzi 1, tawonetsa mawonekedwe a discretized a dielectric circuit fyuluta yokhala ndi coaxial input ndi zotulutsa ma couplers. Ma dielectric discs awiriwa amakhala ngati ma resonator ophatikizidwa kotero kuti chipangizo chonsecho chimakhala chosefera chapamwamba kwambiri.

Katundu/ Kuletsa

Madoko awiri amagwiritsidwa ntchito m'mbali mwa ma coaxial couplers. Nkhope zapansi pa bokosi la mpweya zimatengedwa ngati Malire Okwanira Amagetsi. Kapangidwe kameneka kamapindula ndi ndege yopingasa yopingasa, motero, timangofunika kutengera theka limodzi. Chifukwa chake, tiyenera kulengeza kuti kwa HFWorks simulator pogwiritsa ntchito malire a PEMS; kaya ndi PECS kapena PEMS, zimadalira malo a magetsi pafupi ndi malire a symmetry. Ngati tangential, ndiye PEMS; ngati orthogonal ndiye kuti ndi PECS.

Meshing

Ma mesh amayenera kukhazikika pamadoko ndi nkhope za PEC. Kuyika zinthu izi kumathandizira wosungunula kuwongolera bwino mbali za eddy, ndikuganizira mawonekedwe awo.

Zotsatira

Ma ziwembu osiyanasiyana a 3D ndi 2D alipo kuti agwiritse ntchito, kutengera mtundu wa ntchitoyo komanso gawo lomwe wogwiritsa ntchitoyo akufuna. Pamene tikuchita ndi kayesedwe ka fyuluta, kupanga chiwembu cha S21 kumveka ngati ntchito mwachilengedwe.

Monga tafotokozera koyambirira kwa lipoti ili, HFWorks imapanga ma curve amagetsi pamagawo a 2D komanso pa Smith Charts. Yotsirizirayi ndi yoyenera kufananiza nkhani, ndipo ndiyofunika kwambiri tikamakonza zosefera. Tikuwona apa kuti tili ndi ma pass-band akuthwa komanso kuti timafikira kudzipatula kunja kwa gululo.

Ziwembu za 3D za maphunziro obalalitsa-zigawo zimaphimba magawo osiyanasiyana: ziwerengero ziwiri zotsatirazi zikuwonetsa kugawa kwa magetsi kwa ma frequency awiri (imodzi ili mkati mwa gulu ndipo ina ili kunja kwa gulu)

Mtunduwu ukhoza kupangidwanso pogwiritsa ntchito resonance solver ya HFWorks. Titha kuzindikira mitundu yambiri momwe timafunira. Ndikosavuta kupeza kafukufuku wotere kuchokera ku kafukufuku woyeserera wa S-Parameter : HFWorks imalola kukoka ndikugwetsa kuti ikhazikitse mwachangu kuyerekezera kwa resonance. The resonance solver imaganizira matrix a EM amtunduwu ndikupereka mayankho osiyanasiyana amtundu wa Eigen. Zotsatira zimagwirizana bwino ndi zotsatira za maphunziro akale. Tikuwonetsa apa tebulo lazotsatira:
