Antena y'ihembe rya RM-CPHA1840-12 rizunguruka rikoreshwa mu gupima uburebure bwa 18–40 GHz millimeter-wave

Uko sisitemu za milimetero-wave zikomeza kwaguka mu itumanaho, kumva, gupima, no mu kirere, injeniyeri bakeneye antene zishobora gukomeza imikorere yizewe ya polarization n'imirasire mu gihe cy'idirishya rito. RF MISO'sRM-CPHA1840-12Antena y'ihembe ry'uruzigayagenewe porogaramu za interineti nini kuva kuri18 kugeza kuri 40 GHz, guhuza uburyo bwo gukwirakwiza amashanyarazi bwagutse hamwe n'imiterere mito kandi yoroheje ya mekanike.

Antene iraboneka muri byombiiburyopolarisation y'uruziga(RHCP) or polarisation y'uruziga rw'ibumoso (LHCP)Polarization y’uruziga ifasha kugabanya ubushobozi bwo kumva icyerekezo kiri hagati y’antene zo kohereza n’izo kwakira, bigatuma RM-CPHA1840-12 iba ingirakamaro cyane muri sisitemu aho imiterere ya platform, icyerekezo cy’ikimenyetso, cyangwa inguni yo gushyiraho bishobora guhinduka mu gihe cyo gukora cyangwa gupima.

Hamwe naInyungu isanzwe ya 12 dBi, antene itanga ubuyobozi bw'ingirakamaro ku bipimo bya milimetero-wave mu gihe ikomeza kugenzura imiterere y'ingufu mu gice cy'imikorere. Ibisubizo bya simulation bigaragaza kwiyongera k'ingufu mu gice cyo hejuru cy'uruhererekane rw'ingufu, bishyigikira imirasire yibanzweho ndetse no kunoza imikorere y'uruhererekane mu bipimo bifite ingufu nyinshi.

Guhuza impedance ihamye ni ingenzi cyane mu ruhererekane rw'ibipimo bya interineti. RM-CPHA1840-12 itanga uburyo bwoVSWR isanzwe ya 1.5:1, bifasha kugabanya ingufu zigaragara no gushyigikira kohereza ingufu neza hagati ya antene n'ibikoresho bya RF bihujwe.Igipimo gisanzwe cya axial ratio cya 2 dBbigaragaza ubwiza bwiza bwo gutandukanya imiterere y’urukiramende n’urukiramende, ibyo bikaba ari ngombwa iyo injeniyeri zikeneye kubungabunga ubusugire bwa polarisation no kugabanya kudahuza kw’imiterere y’urukiramende.

Antene ihuza polarizer izengurutse, imiterere y'impinduka mu muyoboro w'amazi, n'ihoni y'inyuma mu buryo bugororotse. Ubu buryo bushyigikira imyitwarire y'imirasire ingana mu miterere y'ingenzi, bigatuma antene ikwiriye gupimwa kure, gupima imirasire ya RF, no gupima antene igereranya. Imiterere y'imirasire itangwa ku murongo kuva kuri 18 kugeza kuri 40 GHz inaha injeniyeri ishusho ifatika y'impinduka mu miyoboro mu buryo bwose bw'imikorere.

Guhuza ikoranabuhanga ni ikindi kintu gikomeye mu gishushanyo. Gupima hafiUburebure bwa mm 129.6 hamwe n'umurambararo wa mm 28, kandi bipima gusagarama 82, RM-CPHA1840-12 ishobora gushyirwa mu bikoresho bito bya laboratwari, sisitemu zo kuyishyira mu mwanya wayo, urubuga rwo mu kirere, n'ibikoresho bya milimetero-wave bikoresha ikirere. Imiterere yayo ya aluminiyumu n'irangi ryayo bitanga uburinganire bw'uburemere buke, kuramba kw'inyubako, n'isura y'umwuga mu nganda.

Imiterere isanzwe ikoresha2.92 mm Interineti y'abagorekandi igashyigikiraIngufu mpuzandengo ya 20 WnaIngufu z'ingufu za 40 W. Hashobora kandi kuganirwaho izindi connector hakurikijwe ibisabwa na sisitemu.

Porogaramu zisanzwe zirimo:

• Isuzuma rya antena yo mu kibuga cya kure
• Gupima imirasire ya RF n'ibyuka bihumanya
• Isuzuma ry'itumanaho rya millimetero
• Isuzuma rya circular-polarisation
• Iterambere rya radar n'uburyo bwo kumenya
• Porogaramu za RF zo mu kirere
• Imishinga yo guhuza laboratwari n'imishinga ikoreshwa mu guhuza sisitemu

Hamwe na yoUmuyoboro w'amakuru wa 18–40 GHz, imikorere ya RHCP cyangwa LHCP ishobora gutoranywa, guhuza impedance ihamye, ingano nto, hamwe n'imikorere yizewe yo kuzenguruka-kuzunguruka,RM-CPHA1840-12itanga igisubizo cyoroshye ku igeragezwa rya milimetero risaba ingufu nyinshi ndetse no guteza imbere sisitemu.
