Amakuru - umuhinduzi

Nk'uburyo bumwe bwo gutanga antene zo mu bwoko bwa waveguide, imiterere ya microstrip kuri waveguide igira uruhare runini mu kohereza ingufu. Uburyo gakondo bwo kohereza microstrip kuri waveguide ni ubu bukurikira. Imashini itwara substrate ya dielectric kandi igashyirwamo umurongo wa microstrip ishyirwa mu cyuho kiri mu rukuta rugari rwa waveguide y'urukiramende. Intera iri hagati ya probe n'urukuta rugufi ruri ku mpera ya waveguide ni inshuro enye z'uburebure bw'uburebure bw'imikorere. Igice kimwe ni cyo gishingiye ku guhitamo substrate ya dielectric, reactance ya probe iterwa n'ingano y'umurongo wa microstrip, naho reactance ya waveguide y'urukiramende rugufi iterwa n'aho urukuta rugufi ruherereye. Ibi bipimo binonosorwa neza kugira ngo bigere ku guhuza impedance ya resistor nziza no kugabanya ikwirakwizwa ry'ingufu.

Imiterere ya Microstrip igana ku murongo w'ishusho mu buryo butandukanye

Ibikoresho bya RFMISO Microstrip Antena:

RM-MA25527-22

RM-MA425435-22

Urubanza
Dukurikije ibitekerezo by’igishushanyo mbonera byatanzwe mu nyandiko, shushanya umuyoboro wa waveguide kuva kuri microstrip converter ufite umuyoboro w’amashanyarazi wa 40 ~ 80GHz. Imiterere itandukanye ni iyi ikurikira. Urugero rusanzwe, umuyoboro wa waveguide utari usanzwe urakoreshwa. Ubunini n’umuyoboro wa dielectric w’ibikoresho bya dielectric bishingiye ku miterere ya impedance ya probe ya microstrip byarahinduwe.
Ibikoresho by'ibanze: dielectric constant 3.0, ubugari 0.127mm
Ingano y'umurongo w'amaza a*b: 3.92mm*1.96mm
Ingano y'icyuho kiri ku rukuta rugari ni 1.08 * 0.268, naho intera iri hagati y'urukuta rugufi ni 0.98. Reba ishusho y'ibipimo bya S n'imiterere ya impedance.

Imbere

Ishusho y'inyuma

Ibipimo bya S: 40G-80G

Igihombo cyo gushyiramo mu gipimo cy'umurongo w'ibanga kiri munsi ya 1.5dB.

Ibiranga impedansi y'icyambu

Zref1: Impedansi yinjiye y'umurongo wa microstrip ni 50 ohms, Zref1: Impedansi y'umuraba muri waveguide ni hafi 377.5 ohms;

Ibipimo bishobora kunozwa: uburebure bw'inyongera ya probe D, ingano ya W * L n'uburebure bw'icyuho kiva ku rukuta rw'uruziga rugufi. Dukurikije aho umurongo wo hagati wa 45G uherereye, uburebure bwa dielectric ni 3.0, uburebure bw'umurambararo bungana na 3.949mm, naho uburebure bw'umurambararo bungana na kimwe cya kane ni 0.96mm. Iyo iri hafi yo guhuza neza ubukana, waveguide ikora muri TE10 main mode, nk'uko bigaragara mu ikwirakwizwa ry'amashanyarazi mu ishusho iri hepfo.
