Seimwe yenzira dzekudyisa dzewaveguide antennas, dhizaini yemicrostrip kune waveguide inoita basa rakakosha mukufambiswa kwesimba. Iyo yechinyakare microstrip kune waveguide modhi yakaita seinotevera. Probe inotakura dielectric substrate uye inodyiswa ne microstrip line inopinzwa mugomba mumadziro akafara erectangular waveguide. Chinhambwe chiri pakati pekuferefeta uye madziro-pfupi-sekete pamagumo ewaveguide angangoita kana mana ekushanda wavelength. chikamu chimwe. Pasi pechigadziro chekusarudza dielectric substrate, kuita kweiyo probe kunoenderana nehukuru hweiyo microstrip line, uye kuita kweiyo pfupi-circuit waveguide kunoenderana nechinzvimbo chepfupi-circuit rusvingo. Aya ma paramita akakwenenzverwa zvakakwana kuti awane impedance yekufananidza yeakachena resistors uye kuderedza kutapurirana kurasikirwa kwesimba.
Microstrip kune waveguide chimiro mune akasiyana maonero
RFMISO Microstrip Antenna akatevedzana zvigadzirwa:
RM-MA25527-22
RM-MA425435-22
Nyaya
Zvinoenderana nemazano ekugadzira akapihwa muzvinyorwa, gadzira waveguide kune microstrip inoshandura ine inoshanda bandwidth ye40 ~ 80GHz. Mienzaniso kubva pamaonero akasiyana ndeaya anotevera. Semuenzaniso wakajairika, isiri-standard waveguide inoshandiswa. Ukobvu uye dielectric kugara kweiyo dielectric zvinhu zvinoenderana neImpedance maitiro eiyo microstrip probe yakagadziridzwa.
Base zvinhu: dielectric inogara 3.0, ukobvu 0.127mm
Waveguide saizi a*b: 3.92mm*1.96mm
Iyo gap size pamadziro akafara ndeye 1.08 * 0.268, uye chinhambwe kubva kupfupi-yedunhu madziro ndeye 0.98. Ona iyo nhamba yeS paramita uye impedance maitiro.

S parameters: 40G-80G
Iko kurasikirwa kwekuisa mupassband renji iri pasi pe1.5dB.
Port impedance maitiro
Zref1: Iyo yekupinza impedance yemutsetse we microstrip ndeye 50 ohms, Zref1: Iyo wave impedance mu waveguide inenge 377.5 ohms;
Maparamita anogona kugadziridzwa: probe yekuisa kudzika D, saizi W * L uye kureba kwegeji kubva kupfupi-yedunhu madziro. Zvinoenderana nepakati frequency point 45G, iyo dielectric inogara iri 3.0, yakaenzana wavelength i3.949mm, uye imwe-kota yakaenzana wavelength ingangoita 0.96mm. Kana yave padyo neyakajeka kuramba inoenderana, iyo waveguide inoshanda muTE10 main mode, sezvakaratidzwa mukugovera kwemagetsi munda mumufananidzo uri pazasi.
