Izindaba - isiguquli

Njengenye yezindlela zokuphakela zama-waveguide antenna, idizayini ye-microstrip to waveguide idlala indima ebalulekile ekudluliselweni kwamandla. Imodeli yendabuko ye-microstrip to waveguide imi kanje. I-probe ephethe i-substrate ye-dielectric futhi ephakelwa umugqa we-microstrip ifakwa esikhaleni odongeni olubanzi lwe-waveguide engunxande. Ibanga phakathi kwe-probe nodonga lwesiyingi esifushane ekugcineni kwe-waveguide cishe liphindwe kane kunobude begagasi obusebenzayo. ingxenye eyodwa. Ngaphansi kwesisekelo sokukhetha i-dielectric substrate, ukusabela kwe-probe kuncike kusayizi womugqa we-microstrip, futhi ukusabela kwe-waveguide ye-short-circuit kuncike endaweni yodonga olufushane. Lawa mapharamitha athuthukiswe ngokuphelele ukuze kufinyelelwe ukufaniswa kwe-impedance kwama-resistors ahlanzekile futhi kuncishiswe ukudluliswa kokulahlekelwa kwamandla.

I-Microstrip kusakhiwo se-waveguide ngemibono ehlukene

Imikhiqizo yochungechunge lwe-RFMISO Microstrip Antenna:

I-RM-MA25527-22

I-RM-MA425435-22

Icala
Ngokwemibono yokuklama enikezwe ezincwadini, klama i-waveguide to microstrip converter enomkhawulokudonsa osebenzayo we-40~80GHz. Amamodeli avela emibonweni ehlukene ami kanje. Njengesibonelo esivamile, i-waveguide engajwayelekile isetshenziswa. Ugqinsi kanye ne-dielectric engaguquki yezinto ze-dielectric zisekelwe kuzici ze-impedance ze-microstrip probe zalungiswa.
Izinto eziyisisekelo: i-dielectric njalo 3.0, ukujiya 0.127mm
Usayizi we-Waveguide a*b: 3.92mm*1.96mm
Usayizi wegebe odongeni olubanzi ngu-1.08 * 0.268, futhi ibanga elisuka odongeni olufushane liyi-0.98. Bona isibalo samapharamitha ka-S nezici ze-impedance.

Ukubuka phambili

Ukubuka ngemuva

Amapharamitha we-S: 40G-80G

Ukulahlekelwa kokufaka ebangeni lokudlula kungaphansi kuka-1.5dB.

Izici ze-Port impedance

I-Zref1: I-impedance yokufaka yomugqa we-microstrip yi-50 ohms, i-Zref1: I-impedance ye-wave ku-waveguide cishe i-377.5 ohms;

Amapharamitha angathuthukiswa: ukujula kokufakwa kwe-probe D, usayizi W*L kanye nobude begebe elisuka odongeni lwesiyingi esifushane. Ngokusho kwephoyinti le-centre frequency point 45G, i-dielectric constant ingu-3.0, i-wavelength elinganayo ingu-3.949mm, kanti i-wavelength elingana nekota eyodwa icishe ibe ngu-0.96mm. Uma isisondele ekufaniseni okumsulwa kokumelana, i-waveguide isebenza kumodi eyinhloko ye-TE10, njengoba kuboniswe ekusabalaliseni insimu kagesi kumfanekiso ongezansi.
