Tekinoroji yekusefa yeMillimeter-wave (mmWave) chinhu chakakosha mukugonesa kutaurirana kwe5G kusina waya, asi inosangana nematambudziko akawanda maererano nehukuru hwemuviri, kushivirira kwekugadzira, uye kugadzikana kwekupisa.
Munyaya yekutaurirana kwe5G kusina waya, ramangwana richatarisa pakushandisa mafrequency ari pamusoro pe20 GHz mukati me mmWave spectrum kuti kuwedzere kugona kwebandwidth, zvichizowedzera mwero wekutumira data.
Zvinozivikanwa kuti nekuda kwema frequency adzo akakwira uye kurasikirwa kwakakosha kwenzira, ma mmWave signals anoda ma antenna madiki. Ma antenna aya akaunganidzwa pamwe chete kuti aumbe ma narrow-beam, high-gain array antennas.
Chimwe chezvinhu zvikuru zvinonetsa mukugadzira mafirita ndechekugadzirisa saizi yeantenna, kunyanya yemafirita ane mafrequency akawanda. Pamusoro pezvo, kushivirira kwekugadzira uye kugadzikana kwekupisa kwemafirita zvinokanganisa zvakanyanya chikamu chega chega chekugadzira chigadzirwa nekugadzirwa kwacho.
Zvipingamupinyi zveSaizi mu mmWave Technology
Mumasystem ekare e antenna array, nzvimbo iri pakati pezvinhu inofanira kunge iri pasi pehafu yehurefu hwewavelength (λ/2) kudzivirira kukanganiswa. Nheyo iyi inoshandawo kune 5G beamforming antennas. Semuenzaniso, antenna inoshanda mu28 GHz band ine nzvimbo iri pakati pezvinhu inosvika 5 mm. Nekuda kweizvozvo, zvikamu zviri mukati mearray zvinofanirwa kunge zvidiki zvakanyanya.
Ma "phased arrays" anoshandiswa mu mmWave applications anowanzo tevedzera dhizaini ye planar structure, sezvakaratidzwa pazasi, apo ma "antenna" (nzvimbo dzeyero) akaiswa pama "printed circuit boards" (PCBs) (nzvimbo dzegirini), uye ma "circuit boards" (nzvimbo dzebhuruu) anogona kubatanidzwa zvakananga ku "antenna board".
Nzvimbo iri pamabhodhi aya edunhu yatove shoma, asi matekinoroji ari kubuda ari kutsvaga zvivakwa zvakati sandara, zvichireva kuti mafirita nemamwe mabhuroko edunhu anofanira kunge madiki zvakanyanya kuti aiswe zvakananga kumashure kwePCB yeantenna.
Mhedzisiro yeKushivirira Kwekugadzira paMafirita
Zvichienderana nekukosha kwemafirita emmWave, kushivirira kwekugadzira kune basa guru, zvichikanganisa mashandiro emafirita pamwe nemutengo.
Kuti tiongorore zvinhu izvi zvakanyanya, takaenzanisa nzira nhatu dzakasiyana dzekugadzira mafirita e26 GHz:
Tafura inotevera inotsanangura kushivirira kwakanyanya kunowanikwa mukugadzirwa:
Kushivirira Kukanganisa paPCB Microstrip Filters
Sezvakaratidzwa pazasi, dhizaini yefirita ye microstrip inoratidzwa.
Mutsetse wekugadzira simulation ndewekuti:
Kuti tidzidze mhedzisiro yekutsungirira pane iyi PCB microstrip filter, ma tolerance masere anogona kunge akanyanya akasarudzwa, zvichiratidza mutsauko unooneka.
Kushivirira Kunokanganisa Mafirita ePCB Stripline
Dhizaini yefirita yemutsetse, inoratidzwa pazasi, ine chivakwa chine matanho manomwe chine mabhodhi e dielectric e30 mil RO3003 kumusoro nepasi.
Kutenderera kweruzha hakuna kudzika zvakanyanya, uye rectangular coefficient yakaderera pane ye microstrip nekuda kwekushaikwa kwe zeros pedyo ne passband, zvichikonzera kushanda zvakanaka kwe harmonic pama frequencies ari kure.
Saizvozvowo, ongororo yekushivirira inoratidza kuti pane kunzwisisika kuri nani kana tichienzanisa nemitsetse ye microstrip.
Mhedziso
Kuti kutaurirana kwe5G kusina waya kuwedzere kumhanya, tekinoroji ye mmWave filter inoshanda pa20 GHz kana kupfuura inokosha. Zvisinei, matambudziko aripo panyaya yehukuru hwemuviri, kugadzikana kwekutsungirira, uye kuoma kwekugadzira.
Saka, kukanganisa kwemvumo pakugadzira kunofanirwa kunyatsofungwa. Zviri pachena kuti mafirita eSMT anoratidza kugadzikana kukuru kupfuura mafirita emicrostrip nestripline, zvichiratidza kuti mafirita eSMT anogona kuva sarudzo huru yekutaurirana kwemmWave mune ramangwana.
