Jwalo ka e nngwe ya mekgwa ya ho fepa ya di-antenna tsa waveguide, moralo wa microstrip ho waveguide o bapala karolo ya bohlokwa phetisong ya eneji. Mohlala wa setso wa microstrip ho waveguide ke o latelang. Probe e jereng substrate ya dielectric mme e fepuwa ke mola wa microstrip e kenngwa ka hara lerako le sephara la waveguide e kgutlonne. Sebaka se pakeng tsa probe le lebota la potoloho e kgutshwane qetellong ya waveguide se ka ba makgetlo a mane ho feta bolelele ba leqhubu la tshebetso. Karolo e le nngwe. Tlas'a motheo wa ho kgetha substrate ya dielectric, karabelo ya probe e itshetlehile ka boholo ba mola wa microstrip, mme karabelo ya waveguide ya potoloho e kgutshwane e itshetlehile ka boemo ba lebota la potoloho e kgutshwane. Diparamitha tsena di ntlafaditswe ka botlalo ho fihlella ho bapisa impedance ya di-resistor tse hlwekileng le ho fokotsa phetiso ya tahlehelo ya eneji.

Sebopeho sa Microstrip ho ea ho waveguide ka maikutlo a fapaneng

Lihlahisoa tsa letoto la li-antenna tsa RFMISO Microstrip:

Ho ya ka mehopolo ya moralo e fanweng dingolweng, rala converter ya waveguide ho ya ho microstrip e nang le bandwidth e sebetsang ya 40 ~ 80GHz. Mehlala e tswang mahlakoreng a fapaneng ke e latelang. E le mohlala o tlwaelehileng, ho sebediswa waveguide e seng ya maemo a tlwaelehileng. Botenya le botsitso ba dielectric ba thepa ya dielectric di itshetlehile hodima Dibopeho tsa impedance tsa probe ya microstrip di ile tsa lokiswa.
Thepa ea motheo: e sa fetoheng ea dielectric 3.0, botenya 0.127mm
Saese ea tataiso ea maqhubu a*b: 3.92mm*1.96mm
Boholo ba sekheo leboteng le sephara ke 1.08*0.268, 'me sebaka se tlohang leboteng la potoloho e khuts'oane ke 0.98. Sheba setšoantšo bakeng sa liparamitha tsa S le litšobotsi tsa impedance.

Pono e ka morao

Liparamente tsa S: 40G-80G

Tahlehelo ea ho kenya ka har'a mefuta ea passband e ka tlase ho 1.5dB.

Litšobotsi tsa impedance ea koung

Zref1: Phetiso ea ho kenya ea mola oa microstrip ke 50 ohms, Zref1: Phetiso ea leqhubu ho waveguide e ka bang 377.5 ohms;

Diparamithara tse ka ntlafatswang: botebo ba ho kenngwa ha probe D, boholo ba W*L le bolelele ba sekgeo ho tloha leboteng la potoloho e kgutshwane. Ho ya ka ntlha ya maqhubu a bohareng ba 45G, kamehla ya dielectric ke 3.0, bolelele ba leqhubu bo lekanang ke 3.949mm, mme bolelele ba leqhubu bo lekanang le kotara bo ka ba 0.96mm. Ha e le haufi le ho bapisa kganyetso e hlwekileng, leqhubu la maqhubu le sebetsa mokgweng o ka sehloohong wa TE10, jwalo ka ha ho bontshitswe kabong ya tshimo ya motlakase setshwantshong se ka tlase.
