Millimeter-wave (mmWave) sefa tekinoroji chinhu chakakosha mukugonesa mainstream 5G isina waya kutaurirana, asi inotarisana nematambudziko mazhinji maererano nehukuru hwemuviri, kushivirira kwekugadzira, uye kugadzikana kwekushisa.
Munharaunda ye5G isina waya yekutaurirana, ramangwana rinotarisa rinozochinjika kune kushandisa mafambiro ari pamusoro pe20 GHz mukati memmWave spectrum kuwedzera bandwidth simba, pakupedzisira ichiwedzera kutapurirana mitengo.
Zvinonyatso zivikanwa kuti nekuda kwemafafitera epamusoro uye kurasikirwa kukuru kwenzira, masaini mammWave anoda madiki ma antennas. Aya antenna akaunganidzwa pamwechete kuti aumbe nhete-danda, yakakwira-gain array antennas.
Imwe yematambudziko ekutanga mukugadzira mafirita ari mukujairana nehukuru hweantenna, kunyanya kune yakakwirira-frequency mafirita. Pamusoro pezvo, kushivirira kwekugadzira uye kugadzikana kwekushisa kwemafirita kunokanganisa zvakanyanya chikamu chose chekugadzirwa kwechigadzirwa uye kugadzira.
Size Constraints mu mmWave Technology
Muchinyakare antenna array masisitimu, nzvimbo pakati pezvinhu inofanirwa kunge isingasviki hafu yewavelength (λ/2) kudzivirira kukanganiswa. Iyi nheyo inoshanda zvakafanana kune 5G beamforming antennas. Semuyenzaniso, antenna inoshanda mu28 GHz bhendi ine element spacing ingangoita 5 mm. Naizvozvo, zvikamu zviri mukati mehurongwa zvinofanirwa kunge zvidiki zvakanyanya.
Phased arrays anoshandiswa mummWave applications anowanzo tora dhizaini yedhizaini, sezvakaratidzwa pazasi, apo antennas (nzvimbo dzeyero) dzakaiswa pamabhodhi edunhu akadhindwa (PCBs) (nzvimbo dzegirinhi), uye mabhodhi edunhu (nzvimbo dzebhuruu) anogona kubatanidzwa perpendicularly kune antenna board.
Nzvimbo iri pamabhodhi edunhu aya yatove ishoma, asi matekinoroji ari kusimukira ari kuongorora zvakatonyanya compact flat zvimiro, zvichireva kuti mafirita uye mamwe madhiraivha edunhu anofanirwa kunge ari madiki kuti aiswe zvakananga kuseri kweantenna PCB.
Mhedzisiro yeKugadzira Kushivirira paMafirita
Tichifunga nezve kukosha kwemmWave mafirita, kushivirira kwekugadzira kunoita basa rakakosha, richipesvedzera kuita kwesefa uye mutengo.
Kuenderera mberi nekuongorora zvinhu izvi, takafananidza matatu akasiyana 26 GHz mafirita nzira dzekugadzira:
Iyi tafura inotevera inoratidza kushivirira kwakanyanya kunowanikwa mukugadzirwa:
Kushivirira Impact paPCB Microstrip Filters
Sezvinoratidzwa pazasi, iyo microstrip sefa dhizaini inoratidzwa.
Iyo dhizaini simulation curve yakaita seinotevera:
Kuti udzidze maitiro ekushivirira pane iyi PCB microstrip sefa, masere anogona kushivirira zvakanyanya akasarudzwa, zvichiratidza mutsauko unoshamisa.
Kushivirira Impact paPCB Stripline Filters
Iyo stripline sefa dhizaini, inoratidzwa pazasi, inomwe-nhanho dhizaini ine 30 mil RO3003 dielectric board kumusoro uye pasi.
Iyo roll-off haina kukwira, uye rectangular coefficient yakaderera kune iyo yemicrostrip nekuda kwekushaikwa kwezero padhuze nepassband, zvichikonzera suboptimal harmonic kuita pamafafitera ari kure.
Saizvozvo, kuongororwa kwekushivirira kunoratidza kunzwa kuri nani kuchienzaniswa nemitsara yemicrostrip.
Mhedziso
Kuti 5G isina waya yekukurukurirana iwane kumhanya nekukurumidza, mmWave sefa tekinoroji inoshanda pa20 GHz kana yakakwirira frequency yakakosha. Nekudaro, matambudziko anoenderera mberi maererano nehukuru hwemuviri, kugadzikana kwekushivirira, uye kuoma kwekugadzira.
Saka, kukanganisa kwekushivirira pamagadzirirwo kunofanirwa kunyatsotariswa. Zviripachena kuti SMT mafirita anoratidza kugadzikana kwakakura kupfuura microstrip uye stripline mafirita, zvichiratidza kuti SMT pamusoro-Mount mafirita anogona kubuda seyakanyanya sarudzo yeramangwana mmWave kutaurirana.
