Millimeter-wave (mmWave) iyungurura rya tekinoroji nikintu cyingenzi mugushoboza itumanaho rya 5G rikoresha itumanaho, nyamara rihura ningorane nyinshi mubijyanye nuburinganire bwumubiri, kwihanganira inganda, hamwe nubushyuhe bwubushyuhe.
Mu rwego rwibanze rwitumanaho rya 5G rudasanzwe, icyerekezo kizaza kizahinduka mugukoresha imirongo iri hejuru ya 20 GHz murwego rwa mmWave kugirango yongere ubushobozi bwumurongo, amaherezo bizamura umuvuduko.
Birazwi neza ko kubera inshuro zabo nyinshi no gutakaza inzira zikomeye, ibimenyetso bya mmWave bikenera antene nto. Izi antene zishyizwe hamwe kugirango zibe urumuri ruto, rwunguka cyane.
Imwe mubibazo byibanze mugushungura ibishushanyo biri muburyo bwo guhuza ibipimo bya antenne, cyane cyane kuri filtri nyinshi. Byongeye kandi, kwihanganira inganda hamwe nubushyuhe bwubushyuhe bwa filteri bigira ingaruka cyane mubice byose byubushakashatsi nibikorwa.
Ingano Inzitizi muri mmWave Technology
Muri antenna gakondo ya sisitemu, intera iri hagati yibintu igomba kuba munsi ya kimwe cya kabiri cyumurambararo (λ / 2) kugirango wirinde kwivanga. Iri hame rireba kimwe na antene ya 5G. Kurugero, antenne ikorera mumutwe wa 28 GHz ifite ikintu gifite intera igera kuri mm 5. Kubwibyo, ibice biri murwego bigomba kuba bito cyane.
Icyiciro cyicyiciro gikoreshwa muri mmWave porogaramu akenshi ifata igishushanyo mbonera cyimiterere, nkuko bigaragara hano hepfo, aho antene (uduce twumuhondo) zishyirwa kumurongo wacapwe (PCBs) (ahantu h'icyatsi), kandi ikibaho cyumuzunguruko (ahantu h'ubururu) gishobora guhuzwa na antenna.
Umwanya uri kuriyi mbaho zumuzunguruko umaze kuba muto, ariko tekinoloji igenda ivuka irimo gushakisha ndetse nuburinganire buringaniye, bivuze ko muyunguruzi hamwe nizindi nzitizi zigomba kuba nto cyane kugirango zishyirwe inyuma ya antenna PCB.
Ingaruka zo Gukora Ihangane Ryungurura
Urebye akamaro ka mmWave muyunguruzi, kwihanganira gukora bigira uruhare runini, bigira ingaruka kumikorere no kuyigura.
Kugirango dukore iperereza kuri ibi bintu, twagereranije uburyo butatu butandukanye bwa 26 GHz bwo kuyungurura:
Imbonerahamwe ikurikira irerekana kwihanganira gukabije kugaragara mu musaruro:
Ingaruka zo kwihanganira PCB Microstrip Muyunguruzi
Nkuko bigaragara hano hepfo, microstrip muyunguruzi igishushanyo kirerekanwa.
Igishushanyo mbonera cyo kwigana ni ibi bikurikira:
Kwiga ingaruka zo kwihanganira kuri PC ya microstrip ya PCB, hatoranijwe umunani ishobora kwihanganira bikabije, byerekana itandukaniro rigaragara.
Ingaruka zo kwihanganira PCB Stripline Muyunguruzi
Igishushanyo mbonera cya filterine, cyerekanwe hepfo, ni ibyiciro birindwi hamwe na 30 mil RO3003 ikibaho cya dielectric hejuru no hepfo.
Kuzunguruka ntibikomeye, kandi coefficente y'urukiramende irutwa na microstrip kubera kubura zeru hafi ya passband, bikavamo imikorere ya suboptimal ihuza imirongo ya kure.
Mu buryo nk'ubwo, isesengura ryo kwihanganira ryerekana sensibilité nziza ugereranije n'imirongo ya microstrip.
Umwanzuro
Kugirango 5G itumanaho ridafite insinga kugirango igere ku muvuduko wihuse, mmWave filter ya tekinoroji ikora kuri 20 GHz cyangwa inshuro nyinshi ni ngombwa. Nyamara, imbogamizi zirakomeje mubijyanye nuburinganire bwumubiri, kwihanganira kwihanganira, hamwe ninganda zikora.
Rero, ingaruka zo kwihanganira ibishushanyo zigomba gusuzumwa neza. Biragaragara ko SMT muyunguruzi yerekana ituze rirenze microstrip na stripline muyunguruzi, byerekana ko SMT yubuso-bwiyungurura bushobora kugaragara nkuburyo nyamukuru bwo guhitamo itumanaho rya mmWave.
