Uburyo bwo guhitamo umukora Antena y'ihembe ry'imirongo ibiri yo gupima RF ya Broadband

Guhitamouruganda rukora antene zifite amahembe abirisi ukugereranya gusa ingano y'amajwi. Ku igeragezwa rya RF rya interineti, antene igomba kandi gutanga uburyo bwo guhuza impedance buhamye, imikorere y'imirasire ishoboka, guhuza neza, n'ibipimo bya mekanike bihuye n'uburyo bwo gupima. Ibi bisobanuro bigira ingaruka ku buryo butaziguye ku gusubiramo mu igeragezwa rya EMC/EMI, gupima antene, gukurikirana ibimenyetso, no guhuza sisitemu.

RF MISO ikora kandi igatanga ibisubizo bya antene za interineti ku bahanga ba RF, abahuza sisitemu, laboratwari n'inganda zikora ibikoresho. Ingero zihagarariye izi zikurikira zose hamwe zikubiyemo uburyo bwo gukoresha antene za interineti.0.4 kugeza kuri 40 GHz, biha abakoresha uburenganzira bwo guhitamo antene y'umurongo ukoreshwa aho gutekereza ko antene imwe ikora ku rugero rwose.

Impamvu Antena z'Amahembe Abiri Zikoreshwa mu Gupima RF ya Broadband

Imiterere y'umurongo w'impande ebyiri yongera umuvuduko w'ingufu wa antene y'ihoni mu gihe igumana imirasire y'icyerekezo na polarization ya linear. Uku guhuza bituma antene iba ingirakamaro iyo sisitemu yo gupima igomba gukora ku rugero rwagutse rw'ingufu idahindura antene kenshi.

Ikoreshwa risanzwe ririmo gupima imyuka ihumanya ikirere, gusuzuma EMC/EMI, gupima ubwiyongere bw'umurasire n'imiterere ya antene, kohereza no kwakira ibimenyetso bya interineti, kugenzura, kugenzura, no kumenya icyerekezo. Uburyo bwiza buracyaterwa n'umurongo ukenewe, inyungu wifuza, intera y'igerageza, umwanya uhari, aho guhuza amashanyarazi bihurira, n'urwego rw'ingufu.

Icyo ugomba gusuzuma mu gihe uhitamo uruganda rukora

1. Gupima inshuro nyinshi hashingiwe ku gice cy'igerageza nyacyo

Tangira ukoresheje umurongo wo hasi kandi wo hejuru usabwa na sisitemu. Intera yagutse ntabwo iba nziza mu buryo bwikora: antene yatoranijwe igomba guhuza n'umurongo nyawo w'igerageza mu gihe ihuye n'ubushobozi busabwa bwo kugera ku musaruro, ubugari bw'umurambararo, ingano, n'ibisabwa mu guhuza. Iyo hari imirongo myinshi, gereranya amasezerano hagati ya moderi imwe ya interineti na antene nyinshi zakozwe neza ku rugero ruto.

2. Guhuza inyungu n'ingufu

Ingaruka z'inyungu zihuza ingengo y'imari n'imbaraga z'ubutaka, mu gihe VSWR igaragaza uburyo ingufu zihererekanywa neza hagati y'umurongo w'itumanaho na antene. Agaciro kasohotse kagomba gusomwa hamwe n'amashusho ashingiye ku nshuro iyo bishoboka. Injeniyeri za RF nazo zigomba kwemeza niba agaciro kavuzwe ari akasanzwe cyangwa kemejwe kandi zigasuzuma urupapuro rw'amakuru ruriho ubu kugira ngo zimenye neza imiterere nyayo irimo kugurwa.

3. Imikorere y'imirasire n'uburyo bwo gutandukanya imirasire

Uburyo bwo gukwirakwiza umurongo mugari (broadband) bwonyine ntibugaragaza imikorere ya antene. Imiterere y'imirasire, ubugari bw'imirasire, kwitandukanya kwa polarization, hamwe n'icyerekezo cya polarization gishobora kuba ingenzi kimwe muri sisitemu zo gupima no gukurikirana. Ibi biranga bifasha kumenya imiterere y'ibizamini, ibisabwa mu guhuza, ndetse no kudasobanukirwa neza ibipimo.

4. Guhuza no guhuza ikoranabuhanga

Ubwoko bw'umuhuza bugomba kuba bujyanye n'uburyo bwo gukora, guteranya insinga, n'ibikoresho byo gupima. Ingano rusange, uburemere, uburyo bwo gushyiramo, n'icyerekezo cya antene nabyo bigira ingaruka ku ishyirwaho ry'icyumba, sisitemu zo gushyiramo, n'uburyo bwo gupima bugendanwa. Igishushanyo mbonera cy'ubuhanga ni ngombwa iyo antene izaba ishyizwe mu gikoresho cyangwa urubuga rusanzwe.

5. Inyandiko z'uruganda n'itumanaho rya tekiniki

Umucuruzi w’inteneri zikoresha interineti (broadband horn) ushoboye agomba gutanga ibisobanuro byihariye ku buryo bwo gukoresha uburyo bwo gukurura no gutumanaho mu buryo bwumvikana neza. Mbere yo gutumiza, banza usangire umurongo usabwa, ikoreshwa, inyungu y’intego, umuhuza, urwego rw’ingufu, imbogamizi zo gushyiraho, n’imiterere y’ibidukikije. Ibi biha uwakoze porogaramu amakuru ahagije yo gusuzuma niba uburyo busanzwe bukwiriye.

Antena zihagarariye RF MISO Broadband Horn

RM-BDHA046-10Igenewe gukora umuyoboro wa interineti uri hagati ya 0.4 na 6 GHz kandi ifite inyungu isanzwe ya 10 dBi. Ibisobanuro byayo ubu bigaragaza polarization ya linear, isolation ya 30 dB cross-polarisation, connector ya SMA Female, hamwe n'imbaraga zikoreshwa zingana na 500 W.

RM-BDHA118-10Ifite umuvuduko wa 1 kugeza kuri 18 GHz hamwe n’ubwiyongere busanzwe bwa 10 dBi. Ingano zayo ntoya zituma iba nziza cyane muri sisitemu za laboratwari aho ikenera gukwirakwizwa binyuze muri mikoroonde.

RM-BDHA440-13Ingano y’umuvuduko kuva kuri 4 kugeza kuri 40 GHz hamwe n’inyungu isanzwe ya 13 dBi. Imiterere y’ubu itanga umuhuza wa 2.92 mm w’igitsina gore cyangwa 2.4 mm w’igitsina gore kandi upima 33 g, ushyigikira imirimo yo gupima no guhuza ibintu aho ingano nto ari ingenzi.

Ibisobanuro byavuzwe haruguru bishingiye ku mpapuro z'amakuru zatanzwe kuri iyi gereranya. Emeza urupapuro rw'amakuru ruheruka n'uburyo bukenewe bwo gushyiraho amakuru ukoresheje RF MISO mbere yo gutumiza.

Gukorana na RF MISO nk'uruganda rukora Antena

RF MISO ihuza ubushakashatsi n'iterambere rya antene, ubwubatsi, umusaruro, n'ibicuruzwa mu kigo kimwe. Ku bagura ubwubatsi, itumanaho rya tekiniki ritaziguye rifasha guhuza ibisabwa mu gukoresha porogaramu n'icyitegererezo cyihariye n'inyandiko zigezweho. RF MISO itanga antene zo gukoresha RF na mikoroonde, harimo antene za broadband horn, antene za gain horn zisanzwe, antene za corrugated horn, antene za waveguide, n'izindi antene.

Mu gihe uhamagara RF MISO, tanga ingano y'imikorere, igerageza cyangwa porogaramu ya sisitemu iteganyijwe, umuhuza wifuza, intego yo kugera ku ntego, ingufu zisabwa, imipaka yo gushyiraho, n'amakuru yose akenewe yo gupima. Itsinda ry'abahanga rishobora gusuzuma moderi zihari no gufasha kumenya aho gutangirira hakwiye.

Ibibazo Bikunze Kubazwa

Ni irihe tandukaniro riri hagati y'ihembe rifite imirongo ibiri n'ihembe risanzwe rikunda kwiyongera?

Ihembe rifite imirongo ibiri muri rusange ritoranywa kugira ngo rikoreshwe mu buryo bwagutse. Ihembe risanzwe rikoreshwa ku mugozi muto iyo hakenewe icyitegererezo cy’izamuka ry’umuvuduko. Guhitamo neza biterwa n’uburyo bwo gupima umuvuduko, izamuka ry’umuvuduko, imiterere, uburyo bwo gupima, n’ibisabwa mu gupima umuvuduko.

Ese antene imwe ya RF MISO ishobora gutwikira 0.4 kugeza 40 GHz?

Oya. Ishusho ya 0.4–40 GHz isobanura uburyo ubwoko bwose bw'amakuru ahagarariye bukoreshwa muri iyi nkuru. Buri antene ifite umurongo wayo bwite w'imikorere, bityo abakoresha bagomba guhitamo icyitegererezo bitewe n'ingano y'amakuru yabo nyayo.

Ni ayahe makuru ngomba kohereza ku ruganda rukora antene zikora amajwi?

Tanga inshuro nke n'inyongera ntarengwa, ikoreshwa, ibisabwa kugira ngo wongere ingufu, polarization, connector, urwego rw'ingufu, umwanya wo kuyishyiramo, uburyo bwo kuyishyiraho, n'amakuru yose akenewe yo gupima. Ibisabwa byuzuye bigabanya amakosa yo guhitamo no kwihutisha isuzuma rya tekiniki.

Ni iyihe moderi nkwiye guhitamo mu gupima umuyoboro wa interineti?

Igisubizo giterwa n'umurongo n'uburyo ukoresha. RM-BDHA046-10 ikoresha 0.4–6 GHz, RM-BDHA118-10 ikoresha 1–18 GHz, naho RM-BDHA440-13 ikoresha 4–40 GHz. Ingano, umuyoboro, ingano, ingufu, n'imikorere y'imirasire nabyo bigomba gusuzumwa mbere yo guhitamo.
