I roto i ngā pūnaha whakawhitiwhiti kōrero ngaruiti, ko te whakanui pūihi he tohu matua mō te ine i te mahi irahiko. Hei tohungakaiwhakarato pūihi ngaruiti, e mōhio ana mātou ki te hiranga o te tatau me te ine tika i te whakanui pūihi mō te arotautanga pūnaha. Ka tangohia e tēnei tuhinga tePūihi 40GHzmePūihi Cassegrainhei tauira hei whakauru taipitopito i te tikanga tatau me ngā āhuatanga mahi o te whakanui pūihi.
1. Pūtake tātaitanga ariā
Ka whakatauhia te pikinga pūihi (dBi) e te aronga me te whai huatanga:
Te pikinga (dBi) = te aronga × te whai huatanga
1. Tātaitanga aronga:
Mā te whakauru i te tauira irahiko, ka taea e ngā pūihi aronga-tiketike (pērā i ngā pūihi Cassegrain) te whakaemi i te pūngao ki roto i tētahi hihi whaiti.
2. Ngā whakaaro mō te whai huatanga:
Me whai whakaaro ki ngā āhuatanga ngaronga e whai ake nei:
- Te ngaronga o te whāngai (pēnei i te kore taurite o te kawenga arataki ngaru)
- Ngaronga rauemi
- Te tika o te tukatuka mata
2. Ngā tikanga ine ngaio
1. Tikanga whakamātautau whakatairite:
Whakatauritea te pūihi kei te whakamatautauria (pēnei i te pūihi 40GHz) me te pūihi haona whakanui paerewa.
2. Whakamātautau mara-tawhiti:
Inehia te tauira irahiko i roto i te rūma pouri o te ngaruiti, he tikanga whakamātautau ngaio tēnei e whakamahia whānuitia ana e ngā **kaituku pūihi**.
3. Whakamātautau tātari whatunga:
Aromatawaihia te ngaronga whakahokinga me te whai huatanga o te irahiko mā te tātari tawhā S.

3. Hangarau manatoko whakatauira
Whakamahia ngā pūmanawa whakatauira hikohiko ngaio pērā i te HFSS me te CST:
- Tātai tika i te whai huatanga o te whakatuwheratanga (he mea tino nui mō te **pūihi Cassegrain** me ētahi atu pūihi whakaata)
- Tātarihia te whakaritenga whāngai
- Arotakehia te pānga o **arataki ngaruutaina**
4. Ngā kaupapa matua o te mahi hangarau
1. Ngā āhuatanga o te auau:
He nui te hononga auau o te whakanui pūihi (pēnei i te hekenga o te whakanui o te pūihi 40GHz i te 30GHz).
2. Ngā āhuatanga taiao:
Ka pā te wāhi tāutanga, te pokanoa e karapoti ana, me ērā atu mea ki te mahi tuturu o te whakanui.
3. Ngā whakaritenga tukanga:
Mā te miihini tika ka taea te whakatutuki i te hoahoa ariā.
Pūihi Kakara (26.5-40GHz)
Tohutohu ngaio:
Mō ngā whakaritenga motuhake pēnei i te **pūihi 40GHz** i roto i te roopu ngaru mirimita, te **pūihi Cassegrain** rānei me te whakanui teitei, me mahi tahi me te **kaituku pūihi ngaruiti** ngaio me ngā āheinga whakamātautau katoa hei whakarite i te mahi a te hua.
Kei a mātou:
- Rūma whakamātautau katoa
- Rōpū ine ngaio
- He wheako hangarau whai rawa
Mō ētahi atu otinga whakapai ake i te whakanui pūihi, tēnā whakapā mai ki tā mātou tīma hangarau.
