A cikin tsarin sadarwa na microwave, ribar eriya babbar alama ce ta auna aikin radiation. A matsayina na ƙwararreMai samar da eriya ta microwave, mun san muhimmancin ƙididdigewa da auna ribar eriya daidai don inganta tsarin. Wannan labarin zai ɗaukiEriya ta 40GHzkumaEriya ta Cassegraina matsayin misalai don gabatar da cikakken bayani game da hanyar lissafi da kuma wuraren amfani na samun eriya.
1. Tushen lissafin ka'ida
Ana ƙayyade ribar eriya (dBi) ta hanyar aiki kai tsaye da inganci:
Riba (dBi) = aiki kai tsaye × inganci
1. Lissafin shugabanci:
An samo ta hanyar haɗa tsarin hasken rana, eriya masu aiki kai tsaye (kamar eriya ta Cassegrain) na iya tattara kuzari a cikin ƙaramin haske.
2. La'akari da inganci:
Ya kamata a yi la'akari da waɗannan abubuwan asara:
- Asarar mai ciyarwa (kamar rashin daidaiton nauyin jagoran raƙuman ruwa)
- Asarar kayan aiki
- Daidaiton sarrafa saman
2. Hanyoyin auna ƙwararru
1. Hanyar gwaji ta kwatantawa:
Kwatanta eriyar da ake gwadawa (kamar eriyar 40GHz) da eriyar ƙaho ta gain.
2. Gwajin filin nesa:
Auna tsarin hasken rana a cikin dakin duhu na microwave, wanda wata hanya ce ta gwaji ta ƙwararru da masu samar da eriya ke amfani da ita**.
3. Gwajin nazarin hanyar sadarwa:
Kimanta asarar dawowa da ingancin radiation ta hanyar nazarin sigogin S.

3. Fasahar tabbatar da kwaikwayo
Yi amfani da software na kwaikwayo na lantarki na ƙwararru kamar HFSS da CST:
- Yi lissafin ingancin buɗewa daidai (musamman mahimmin mahimmanci ga ** eriya ta Cassegrain** da sauran eriya masu haskakawa)
- Yi nazarin daidaiton ciyarwa
- Kimanta tasirin **jagoran igiyar ruwakaya**
4. Muhimman abubuwan da suka shafi aikin injiniya
1. Halayen mita:
Karuwar eriya tana da alaƙa mai mahimmanci tsakanin mitar (kamar yadda karuwar eriya ta 40GHz za ta ragu a 30GHz).
2. Abubuwan da suka shafi muhalli:
Wurin shigarwa, tsangwama da ke kewaye, da sauransu za su shafi ainihin aikin riba.
3. Bukatun tsari:
Injin gyara yana tabbatar da cewa za a iya cimma ƙirar ka'idar.
Eriya ta Cassegrain (26.5-40GHz)
Shawarwari na ƙwararru:
Don buƙatu na musamman kamar eriya ta **40GHz** a cikin millimeter wave band ko **eriya ta Cassegrain** tare da babban riba, ana ba da shawarar yin aiki tare da ƙwararren mai samar da eriya ta microwave** tare da cikakken ƙarfin gwaji don tabbatar da aikin samfur.
Muna da:
- Cikakken ɗakin gwaji
- Ƙungiyar auna ƙwararru
- Kwarewa mai zurfi a fannin injiniya
Don ƙarin hanyoyin ingantawa na samun eriya, da fatan za a tuntuɓi ƙungiyar fasaha ta mu.
