Mumuzunguruko cyangwa sisitemu ya microwave, umuzunguruko cyangwa sisitemu akenshi bigizwe nibikoresho byinshi byibanze bya microwave nka filtri, guhuza, kugabanya amashanyarazi, nibindi. Twizera ko binyuze muri ibyo bikoresho, bishoboka kohereza neza ibimenyetso byerekana ibimenyetso kuva kumurongo umwe ujya ikindi gifite igihombo gito;
Muri sisitemu ya radar yimodoka yose, guhindura ingufu ahanini bikubiyemo guhererekanya ingufu ziva muri chip kugeza kuri federasiyo ku kibaho cya PCB, ihererekanyabubasha mu mubiri wa antene, hamwe n’imirasire ikora neza na antene.Mubikorwa byose byo kohereza ingufu, igice cyingenzi nigishushanyo mbonera.Guhindura muri milimetero ya sisitemu ya sisitemu harimo cyane cyane microstrip kugirango isimbuze icyerekezo cyahinduwe (SIW), microstrip kugirango ihindurwe, SIW kugirango ihindurwe, coaxial to waveguide ihinduka, umurongo woguhindura umurongo wubwoko butandukanye.Iki kibazo kizibanda kuri microband SIW igishushanyo mbonera.
Ubwoko butandukanye bwubwikorezi
Microstripni imwe mu mikorere ikoreshwa cyane muburyo bwo kugereranya microwave nkeya.Ibyiza byingenzi byingenzi ni imiterere yoroshye, igiciro gito hamwe no kwishyira hamwe hamwe nibice byo hejuru.Imirongo isanzwe ya microstrip ikorwa hifashishijwe imiyoboro kuruhande rumwe rwa dielectric layer substrate, ikora indege imwe yubutaka kurundi ruhande, hamwe numwuka hejuru.Umuyoboro wo hejuru ni ibikoresho byayobora (ubusanzwe umuringa) byakozwe mumigozi ifunganye.Ubugari bwumurongo, ubunini, ugereranije uruhushya, hamwe nigihombo cya dielectric tangent ya substrate nibintu byingenzi.Byongeye kandi, ubunini bwuyobora (ni ukuvuga uburebure bwa metallisation) hamwe nubushobozi bwuyobora nabyo birakomeye kuri frequency nyinshi.Mugusuzumana ubwitonzi ibyo bipimo no gukoresha imirongo ya microstrip nkigice cyibanze kubindi bikoresho, ibikoresho byinshi byacapwe na microwave hamwe nibigize bishobora gushushanywa, nka filteri, guhuza, kugabana amashanyarazi / guhuza, kuvanga, nibindi. Ariko uko inshuro ziyongera (mugihe wimukiye ugereranije na microwave inshuro nyinshi) igihombo cyo kwandura cyiyongera kandi imirasire ibaho.Kubwibyo, imiyoboro ya Hollow tube nkurukiramende rwurukiramende irahitamo kubera igihombo gito kuri radiyo nyinshi (nta mirasire).Imbere ya waveguide mubisanzwe ni umwuka.Ariko iyo ubishaka, irashobora kuzuzwa ibikoresho bya dielectric, ikayiha igice gito cyambukiranya icyuka cyuzuye gaze.Nyamara, imiyoboro idafite imiyoboro ikunze kuba nini, irashobora kuba iremereye cyane cyane kuri radiyo yo hasi, bisaba ibisabwa cyane mu nganda kandi birahenze, kandi ntibishobora guhuzwa nububiko bwanditse.

Ibindi ni imiyoborere yubuvanganzo hagati ya microstrip imiterere na waveguide, bita substrate integuro ya waveguide (SIW).SIW ni imiterere ihuriweho na waveguide isa nuburyo bwahimbwe kubintu bya dielectric, hamwe nuyobora hejuru no hepfo hamwe numurongo ugizwe numurongo wibyuma bibiri bigize umuhanda.Ugereranije na microstrip hamwe nuburyo bwa waveguide, SIW irahendutse, ifite uburyo bworoshye bwo gukora, kandi irashobora guhuzwa nibikoresho bya planari.Mubyongeyeho, imikorere kuri frequency nyinshi iruta iy'imiterere ya microstrip kandi ifite imiterere ya disikuru.Nkuko bigaragara ku gishushanyo 1;
SIW umurongo ngenderwaho
Substrate ihuriweho na flawide (SIWs) ihuriweho nuburinganire busa nububiko bwahimbwe ukoresheje imirongo ibiri yicyuma cyinjijwe muri dielectric ihuza ibyuma bibiri bisa.Imirongo yicyuma ikoresheje umwobo ikora urukuta rwuruhande.Iyi miterere ifite ibiranga imirongo ya microstrip na waveguide.Ibikorwa byo gukora nabyo bisa nibindi bikoresho byacapwe.Ubusanzwe SIW geometrie yerekanwa mu gishushanyo cya 2.1, aho ubugari bwayo (ni ukuvuga gutandukanya vias mu cyerekezo cyerekezo (as)), diameter ya vias (d) n'uburebure bw'ikibanza (p) ikoreshwa mugushushanya imiterere ya SIW Ibipimo byingenzi bya geometrike (byerekanwe ku gishushanyo cya 2.1) bizasobanurwa mu gice gikurikira.Menya ko uburyo bwiganje ari TE10, kimwe nurukiramende.Isano iri hagati yo guca inshuro fc yumwuka wuzuye umuyaga (AFWG) hamwe na dielectric yuzuye umuyaga (DFWG) nubunini a na b niyo ngingo yambere yo gushushanya SIW.Kumurongo wuzuye wuzuye, umurongo wo guhagarika ni nkuko bigaragara muri formula ikurikira
SIW imiterere shingiro nuburyo bwo kubara [1]
aho c ni umuvuduko wumucyo mumwanya wubusa, m na n nuburyo, a nubunini burebure bwa waveguide, na b nubunini bugufi.Iyo umurongo wogukora ukora muburyo bwa TE10, birashobora koroshya fc = c / 2a;iyo umurongo wuzuye wuzuye dielectric, uburebure bwagutse a bubarwa na ad = a / Sqrt (εr), aho εr ni dielectric ihoraho yikigereranyo;murwego rwo gukora SIW ikora muburyo bwa TE10, unyuze mumwanya wa p, diameter d nu mpande nini nkuko bigomba guhaza formula iburyo hejuru yishusho hepfo, kandi hariho na formulaire ya d <λg na p <2d [ 2];
aho λg nuburebure bwumurongo wumurongo: Mugihe kimwe, ubunini bwa substrate ntibuzagira ingaruka kubishushanyo mbonera bya SIW, ariko bizagira ingaruka kubutaka bwimiterere, bityo ibyiza-byo gutakaza igihombo cyumubyimba mwinshi cyane .
Microstrip kuri SIW ihinduka
Iyo microstrip imiterere ikeneye guhuzwa na SIW, inzibacyuho ya microstrip ni bumwe muburyo bwingenzi bwinzibacyuho bwatoranijwe, kandi inzibacyuho isanzwe itanga umurongo mugari ugereranije nibindi byacapwe.Imiterere yinzibacyuho yateguwe neza ifite ibitekerezo bike cyane, kandi igihombo cyatewe ahanini nigihombo cya dielectric nuyobora.Guhitamo ibikoresho bya substrate nuyobora byerekana ahanini igihombo cyinzibacyuho.Kubera ko umubyimba wa substrate ubangamira ubugari bwumurongo wa microstrip, ibipimo byinzibacyuho bigomba guhinduka mugihe umubyimba wa substrate uhindutse.Ubundi bwoko bwa coplanar waveguide (GCPW) nabwo bukoreshwa cyane muburyo bwo kohereza imiyoboro muri sisitemu nyinshi.Abayobora kuruhande hafi yumurongo wohereza hagati nabo bakora nkubutaka.Muguhindura ubugari bwibiryo nyamukuru hamwe nu cyuho kubutaka bwuruhande, ibisabwa biranga impedance irashobora kuboneka.
Microstrip kuri SIW na GCPW kuri SIW
Igishushanyo gikurikira ni urugero rwigishushanyo cya microstrip kuri SIW.Uburyo bukoreshwa ni Rogers3003, dielectric ihoraho ni 3.0, igihombo nyacyo ni 0.001, n'ubugari ni 0.127mm.Ubugari bwibiryo kumpande zombi ni 0.28mm, bihuye nubugari bwibiryo bya antenna.Binyuze mu mwobo wa diameter ni d = 0.4mm, n'umwanya p = 0,6mm.Ingano yo kwigana ni 50mm * 12mm * 0.127mm.Igihombo muri rusange muri passband ni 1.5dB (irashobora kugabanuka mugutezimbere intera yagutse).
SIW imiterere n'ibipimo bya S.
