Njengenye yeendlela zokutyisa zee-eriyali zamaza, uyilo lwe-microstrip ukuya kwi-waveguide idlala indima ebalulekileyo kuthumelo lwamandla.I-microstrip yesiko kwimodeli ye-waveguide ilandelayo.I-probe ephethe i-dielectric substrate kwaye idliwe ngumgca we-microstrip ifakwe kwi-gap kudonga olubanzi lwe-waveguide ye-rectangular.Umgama phakathi kweprobe kunye nodonga olufutshane olusekupheleni kwe-waveguide malunga namaxesha amane obude bokusebenza.inxalenye enye.Ngaphantsi kwesiseko sokukhetha i-dielectric substrate, ukuphendulwa kweprobe kuxhomekeke kubukhulu bomgca we-microstrip, kunye nokuphendula kwe-waveguide ye-short-circuit waveguide kuxhomekeke kwindawo yodonga olufutshane.Ezi parameters ziphuculwe ngokubanzi ukuze kufezekiswe ukuhambelana kwe-impedance ye-resistors ecocekileyo kunye nokunciphisa ukuhanjiswa kwelahleko yamandla.
I-Microstrip kwisakhiwo se-waveguide kwiimbono ezahlukeneyo
Iimveliso ze-RFMISO Microstrip Antenna:
RM-MA25527-22
RM-MA425435-22
Ityala
Ngokweengcamango zoyilo ezinikezelwe kuncwadi, yila i-waveguide kwi-converter ye-microstrip kunye ne-bandwidth yokusebenza ye-40 ~ 80GHz.Iimodeli ezivela kwiimbono ezahlukeneyo zimi ngolu hlobo lulandelayo.Njengomzekelo oqhelekileyo, i-waveguide engekho-standard isetyenziswa.Ubunzima kunye ne-dielectric constant of the dielectric material isekelwe kwiimpawu ze-impedance ze-microstrip probe zahlengahlengiswa.
Izinto ezisisiseko: i-dielectric rhoqo 3.0, ubukhulu be-0.127mm
Ubungakanani besikhokelo samaza a * b: 3.92mm * 1.96mm
Ubungakanani be-gap eludongeni olubanzi yi-1.08 * 0.268, kwaye umgama ukusuka eludongeni olufutshane lwesekethe ngu-0.98.Jonga umzobo we-S parameters kunye neempawu zokuphazamiseka.
Ukujonga ngaphambili
Isipili sangaphakathi
Iiparamitha ze-S: 40G-80G
Ilahleko yokufaka kuluhlu lokupasa lungaphantsi kwe-1.5dB.
Iimpawu zePort impedance
I-Zref1: I-impedance yegalelo lomgca we-microstrip yi-50 ohms, i-Zref1: Ukuxhatshazwa kwamaza kwi-waveguide malunga ne-377.5 ohms;
Iiparamitha ezinokuthi ziphuculwe: ubunzulu bokufakwa kwe-probe D, ubukhulu be-W * L kunye nobude besithuba ukusuka kudonga olufutshane.Ngokweziko le-frequency point 45G, i-dielectric constant yi-3.0, i-wavelength elinganayo yi-3.949mm, kunye ne-quarter ye-wavelength elinganayo malunga ne-0.96mm.Xa isondele ekuchaseni ukuchasana okucocekileyo, i-waveguide isebenza kwimodi ephambili ye-TE10, njengoko kubonisiwe kwintsimi yombane yokusasazwa kumfanekiso ongezantsi.
