Izindaba - isiguquli

Njengenye yezindlela zokudla zama-antenna e-waveguide, ukwakheka kwe-microstrip kuya ku-waveguide kudlala indima ebalulekile ekudlulisweni kwamandla. Imodeli yendabuko ye-microstrip kuya ku-waveguide imi kanje. I-probe ephethe i-dielectric substrate futhi ephakelwa umugqa we-microstrip ifakwa esikhaleni odongeni olubanzi lwe-waveguide engunxande. Ibanga phakathi kwe-probe nodonga lwe-short-circuit ekugcineni kwe-waveguide cishe liphindwe kane kune-operating wavelength. Ngaphansi kwesisekelo sokukhetha i-dielectric substrate, i-reactance ye-probe incike kusayizi womugqa we-microstrip, kanti i-reactance ye-short-circuit waveguide incike endaweni yodonga lwe-short-circuit. Lawa mapharamitha alungiselelwe ngokuphelele ukufeza ukufaniswa kwe-impedance kwama-resistor ahlanzekile nokunciphisa ukudluliselwa kokulahlekelwa amandla.

Isakhiwo se-Microstrip kuya ku-waveguide emibonweni ehlukene

Imikhiqizo yochungechunge lwe-RFMISO Microstrip Antenna:

RM-MA25527-22

I-RM-MA425435-22

Ikesi
Ngokwemibono yokuklama enikezwe ezincwadini, klama i-waveguide kuya ku-microstrip converter ene-bandwidth yokusebenza engu-40 ~ 80GHz. Amamodeli avela emibonweni ehlukene alandelayo. Njengesibonelo esivamile, kusetshenziswa i-waveguide engeyona ejwayelekile. Ubukhulu kanye ne-dielectric constant yezinto ze-dielectric kusekelwe ku- Izici ze-impedance ze-probe ye-microstrip zilungisiwe.
Izinto eziyisisekelo: i-dielectric constant 3.0, ubukhulu obungu-0.127mm
Usayizi we-Waveguide a*b: 3.92mm*1.96mm
Usayizi wesikhala odongeni olubanzi ngu-1.08*0.268, kanti ibanga ukusuka odongeni olufushane lingu-0.98. Bheka isithombe ukuze uthole amapharamitha e-S kanye nezici ze-impedance.

Ukubuka kwangaphambili

Ukubuka kwangemuva

Amapharamitha e-S: 40G-80G

Ukulahlekelwa kokufakwa ebangeni le-passband kungaphansi kwe-1.5dB.

Izici ze-port impedance

I-Zref1: I-input impedance yomugqa we-microstrip ingu-50 ohms, i-Zref1: I-wave impedance ku-waveguide icishe ibe ngu-377.5 ohms;

Amapharamitha angathuthukiswa: ukujula kokufakwa kwe-probe D, usayizi W*L kanye nobude besikhala esivela odongeni lwe-short-circuit. Ngokusho kwephuzu lemvamisa ephakathi engu-45G, i-dielectric constant ingu-3.0, ubude be-wavelength obulinganayo bungu-3.949mm, kanti ubude be-wavelength obulinganayo bekota bungu-0.96mm. Uma iseduze nokulinganisa ukumelana okumsulwa, i-waveguide isebenza kumodi eyinhloko ye-TE10, njengoba kuboniswe ekusakazweni kwensimu kagesi esithombeni esingezansi.
