Mawonekedwe:
- Mtengo wapatali wa magawo VSWR
Short size waveguide termination ndi mawonekedwe a waveguide opangidwa mwapadera okhala ndi miyeso yayifupi, yomwe imagwiritsidwa ntchito kuyamwa ndikutaya mphamvu zama siginecha amphamvu otsika a microwave, potero amakwaniritsa kugwiritsa ntchito ma siginecha osafunikira pozungulira. Mfundo ya kuyimitsa kwa ma waveguide yayifupi imatengera njira ziwiri: kuwonetsera ndi kuyamwa. Chizindikiro cha microwave chikadutsa pakuyimitsidwa kwakanthawi kochepa mu waveguide, siginecha ina imawonekeranso kugwero, ndipo gawo lina la siginecha lidzatengedwa ndi kuthetsedwa kwa waveguide. Mwa kupanga ndi kusankha koyenera, kutayika kowunikira kumatha kuchepetsedwa ndipo kutayika kwa kuyamwa kumatha kukulitsidwa.
1. Kukhala ndi dongosolo losavuta.
2. Kukula kochepa
3. Mtengo wotsika wopanga
4.The stand wave index ndiabwino kwambiri.
1. Kuwongolera ndi kuyezetsa dera: Kuletsa kwa ma waveguide aafupi kumagwiritsidwa ntchito kwambiri pakuwongolera ndi kuyesa mabwalo a microwave. Mwa kulumikiza kuthetsedwa kwa waveguide ku doko lotuluka la dera kuti liyesedwe, kuwunikira kwa ma siginecha kumatha kupewedwa, potero kumateteza zigawo zadera kuti zisawonongeke ndikuwonetsetsa kuti zoyeserera zolondola komanso zodalirika.
2. Reflection coefficient muyeso: Poyezera koyezetsa kofananira, magwiridwe antchito ofananira a dera lomwe akuyesedwa akhoza kuyesedwa. Kutha kwa ma waveguide aafupi angagwiritsidwe ntchito ngati kumalizidwa kwanthawi zonse, ndikuyerekeza ndi dera lomwe likuyesedwa, poyesa kuchuluka kwa chizindikiro chomwe chikuwonetsedwa, choyezera chowoneka bwino chikhoza kuwerengedwa ndipo magwiridwe antchito ofananirako amatha kuwunikidwa.
3. Kuyeza kwa phokoso: Kutha kwa ma waveguide aafupi amakhalanso ndi gawo lofunikira pakuyezera phokoso. Pogwiritsa ntchito mayamwidwe ake, ma sign aphokoso amatha kudyedwa bwino, potero amachepetsa kusokoneza kwa phokoso pakuyezera.
Kuyesa kwa antenna ndi RF: Pakuyesa kwa mlongoti ndi RF, kuimitsidwa kwa ma waveguide aafupi angagwiritsidwe ntchito kutengera kusagwiritsa ntchito mphamvu kwa chilengedwe chomwe mlongoti uli. Mwa kulumikiza kuthetsedwa ku doko lotulutsa mlongoti, magwiridwe antchito a mlongoti ndi makina amatha kuyesedwa, kusinthidwa, ndi kukhathamiritsa.
Qualwaveimapereka VSWR yotsika komanso kuimitsidwa kwa ma waveguide ang'onoang'ono kumaphimba ma frequency 5.38 ~ 40GHz. Kuletsa kumagwiritsidwa ntchito kwambiri m'mapulogalamu ambiri.
