Monga imodzi mwa njira zodyetsera za tinyanga ta ma waveguide, mapangidwe a microstrip to waveguide amatenga gawo lofunikira pakufalitsa mphamvu.Mtundu wa microstrip to waveguide model uli motere.Chofufuzira chonyamula gawo la dielectric ndikudyetsedwa ndi chingwe cha microstrip chimalowetsedwa mumpata wa khoma lalikulu la mafunde a rectangular waveguide.Mtunda pakati pa probe ndi khoma lachifupi-circuit kumapeto kwa waveguide ndi pafupifupi kanayi kutalika kwa ntchito.gawo limodzi.Pansi pa chisankho chosankha gawo la dielectric, momwe pulojekitiyi imayendera kumadalira kukula kwa mzere wa microstrip, ndipo momwe mafunde afupikitsa amayendera zimadalira malo a khoma lachifupi.Magawo awa amakometsedwa bwino kuti akwaniritse zofananira za ma resistors oyera ndikuchepetsa kufalikira kwa mphamvu.
Microstrip to waveguide structure mumawonedwe osiyanasiyana
Zogulitsa za RFMISO Microstrip Antenna:
RM-MA25527-22

Malinga ndi malingaliro apangidwe omwe aperekedwa m'mabuku, pangani ma waveguide to microstrip converter yokhala ndi bandwidth yogwira ntchito ya 40 ~ 80GHz.Zitsanzo zamitundu yosiyanasiyana ndi izi.Monga chitsanzo chodziwika bwino, ma waveguide osakhala okhazikika amagwiritsidwa ntchito.Makulidwe ndi ma dielectric okhazikika azinthu za dielectric zimatengera Makhalidwe a impedance ya kafukufuku wa microstrip adasinthidwa.
Zida zoyambira: dielectric nthawi zonse 3.0, makulidwe 0.127mm
Waveguide kukula a * b: 3.92mm * 1.96mm
Kukula kwapakati pakhoma lalikulu ndi 1.08 * 0.268, ndipo mtunda kuchokera pakhoma lalifupi ndi 0,98.Onani chithunzi cha magawo a S ndi mawonekedwe a impedance.
Kuwona kutsogolo
Mawonedwe akumbuyo
S magawo: 40G-80G
Kutayika koyikapo mumtundu wa passband ndikochepera 1.5dB.
Makhalidwe a Port impedance
Zref1: Kulowetsedwa kwa mzere wa microstrip ndi 50 ohms, Zref1: Kusokoneza mafunde mu waveguide ndi pafupifupi 377.5 ohms;
Magawo omwe amatha kukhathamiritsa: kuzama kwa probe D, kukula kwa W * L ndi kutalika kwa kusiyana kuchokera pakhoma lalifupi.Malinga ndi ma frequency point 45G, dielectric constant ndi 3.0, wavelength yofanana ndi 3.949mm, ndipo kotala yofananira kutalika ndi pafupifupi 0.96mm.Ili pafupi ndi kufananitsa koyera kofananira, ma waveguide amagwira ntchito munjira yayikulu ya TE10, monga momwe zikuwonetsedwera pagawo lamagetsi lamagetsi pachithunzi pansipa.
