Sida mid ka mid ah hababka quudinta ee anteenooyinka waveguide, naqshadeynta microstrip to waveguide ayaa door muhiim ah ka ciyaarta gudbinta tamarta. The microstrip dhaqameed in model waveguide waa sida soo socota. Baadhitaanka sidda substrate dielectric oo lagu quudiyo xariiqda microstrip ayaa la geliyaa farqiga u dhexeeya gidaarka ballaaran ee waveguide leydi ah. Fogaanta udhaxeysa baaritaanka iyo gidaarka wareega-gaaban ee dhamaadka mawjadaha waa qiyaastii afar jeer dhererka hirarka shaqada. qayb ka mid ah. Marka la eego dhismaha xulashada substrate dielectric, falcelinta baaritaanka waxay kuxirantahay xajmiga khadka microstrip, iyo falcelinta waveguide-gaaban waxay kuxirantahay booska derbiga wareega gaaban. Halbeegyadan si dhammaystiran ayaa loo hagaajiyay si loo gaaro isbarbardhigga is-hortaaga ee iska caabiyeyaasha saafiga ah iyo in la yareeyo gudbinta lumista tamarta.

Microstrip si ay u waveguide qaab dhismeedka aragtiyo kala duwan

RFMISO Microstrip Antenna badeecooyin taxane ah:

Kiis
Marka loo eego fikradaha naqshadeynta ee lagu bixiyo suugaanta, u qaabee waveguide si aad u beddesho microstrip oo leh bandwidth shaqeynaya 40 ~ 80GHz. Moodooyinka laga soo xigtay dhinacyo kala duwan waa sida soo socota. Tusaale ahaan, hagaha mawjada aan caadiga ahayn ayaa la isticmaalaa. Dhumucda iyo joogtada dielectric ee walxaha dielectric waxay ku salaysan yihiin sifooyinka impedance ee baaritaanka microstrip ayaa la hagaajiyay.
Waxyaabaha salka: dielectric joogto ah 3.0, dhumucdiisuna waa 0.127mm
Cabbirka waveguide a*b: 3.92mm*1.96mm
Cabbirka farqiga derbiga ballaaran waa 1.08 * 0.268, masaafada u jirta derbiga gaaban waa 0.98. Fiiri jaantuska cabbirrada S iyo astaamaha impedance.

Xaddiga S: 40G-80G

Luminta galinta ee xadka baasaaska ayaa ka yar 1.5dB.

Tilmaamaha xannibaadda dekedda

Zref1: Xakamaynta gelinta ee xariiqda microstrip waa 50 ohms, Zref1: Xakamaynta mawjada ee waveguide waa qiyaastii 377.5 ohms;

Halbeegyada la hagaajin karo: qoto dheer ee gelinta baaritaanka D, cabbirka W*L iyo dhererka farqiga u dhexeeya derbiga wareegga gaaban. Marka loo eego barta inta jeer ee xarunta 45G, joogtaynta dielectric waa 3.0, mawjada u dhiganta waa 3.949mm, iyo hal-meelood meel u dhiganta hirarku waa ilaa 0.96mm. Marka ay ku dhowdahay isbarbardhigga iska caabbinta saafiga ah, waveguide wuxuu ku shaqeeyaa qaabka ugu muhiimsan ee TE10, sida ku cad qaybinta goobta korontada ee sawirka hoose.
