Hei urutau ki ngā whakaritenga koki pūihi o te hua hou, me te tohatoha i te pokepokea ai pepa PCB o te whakatupuranga o mua, ka taea te whakamahi i te tahora pūihi e whai ake nei hei whakatutuki i te whakanui pūihi o te 14dBi@77GHz me te mahi irahiko o te 3dB_E/H_Beamwidth=40°. Mā te whakamahi i te pereti Rogers 4830, te matotoru 0.127mm, Dk=3.25, Df=0.0033.
Te tahora o te pūihi
I te ahua o runga ake nei, e whakamahia ana he pūihi whatunga iti-ripene. Ko te pūihi rarangi whatunga iti-ripene he āhua pūihi i hangaia mā te whakarara i ngā huānga hihi me ngā raina tuku i hangaia e ngā mowhiti iti-ripene N. He hanganga kiato, he nui te whiwhinga, he māmā te whāngai me te Māmā o te hanga me ētahi atu painga. Ko te tikanga matua o te whakarara ko te whakarara raina, he rite ki ngā pūihi whatunga iti noa, ā, ka taea te tukatuka mā te hangarau whakairo. Ko te aukati o te whatunga, te taunga whāngai, me te hanganga hononga e whakatau tahi ana i te tohatoha o te iahiko puta noa i te rarangi, ā, ko ngā āhuatanga hihi e whakawhirinaki ana ki te āhua o te whatunga. Ka whakamahia he rahi whatunga kotahi hei whakatau i te auau pokapū o te pūihi.

Tātaritanga mātāpono
He rite te kaha o te ia e rere ana i te ahunga poutū o te huānga rarangi, he rite te kaha whakamuri, ā, he ngoikore te kaha o te irahiko, he iti noa te pānga ki te mahi a te pūihi. Whakatakotoria te whānui o te pūtau l1 ki te haurua o te roanga ngaru, ā, whakatikatikahia te teitei o te pūtau (h) kia eke ki te rerekētanga ā-wāhanga o te 180° i waenga i a0 me b0. Mō te irahiko whānui, ko te rerekētanga ā-wāhanga i waenga i ngā pūwāhi a1 me b1 he 0°.
Hanganga huānga rarangi
Hanganga whāngai
Ko ngā pūihi momo-mātiti he tikanga whakamahi i tētahi hanganga whāngai coaxial, ā, kua honoa te whāngai ki te tuara o te PCB, nō reira me hoahoa te whāngai mā roto i ngā paparanga. Mō te tukatuka tuturu, ka puta he hapa tika, ka pā ki te mahi. Hei whakatutuki i ngā mōhiohio āhuahanga kua whakaahuatia i te pikitia i runga ake nei, ka taea te whakamahi i tētahi hanganga whāngai rerekētanga papatahi, me te whakahihiri kaha ōrite i ngā tauranga e rua, engari he rerekētanga āhuahanga o te 180°.
Hanganga whāngai honohono[1]
Ko te nuinga o ngā pūihi whāngai whatunga iti-ripeka e whakamahi ana i te whāngai coaxial. Ko ngā tūranga whāngai o te pūihi whāngai whatunga e wehea ana ki ngā momo e rua: te whāngai pokapū (te pūwāhi whāngai 1) me te whāngai taha (te pūwāhi whāngai 2 me te pūwāhi whāngai 3).
Hanganga huinga whatunga noa
I te wā e whāngai ana i te taha, ka horapa ngā ngaru haere puta noa i te whatunga katoa i runga i te pūihi whatunga, he whatunga mutunga-ahi kotahi-aronga kore-oro. Ka taea te whakamahi i te pūihi whatunga hei pūihi ngaru haere me te pūihi oro. Mā te whiriwhiri i te auau tika, te pūwāhi whāngai, me te rahi whatunga ka taea e te whatunga te mahi i roto i ngā āhua rerekē: te ngaru haere (te horapa auau) me te oro (te tuku taha). Hei pūihi ngaru haere, ka tangohia e te pūihi whatunga he āhua whāngai taha-whāngai, me te taha poto o te whatunga he paku nui ake i te kotahi-tuatoru o te roangaru ārahi, me te taha roa i waenganui i te rua me te toru ngā wā o te roa o te taha poto. Ka tukuna te iahiko i te taha poto ki tērā taha, ā, he rerekētanga ā-wāhanga i waenganui i ngā taha poto. Ka tukuna e ngā pūihi whatunga ngaru haere (kore-oro) ngā hihi whakarara e peka ana mai i te ahunga noa o te papa whatunga. Ka huri te ahunga hihi me te auau, ā, ka taea te whakamahi mō te matawai auau. Ina whakamahia te pūihi whatu hei pūihi whakapūmau, ka hangaia ngā taha roa me ngā taha poto o te whatu kia kotahi te roangaru kawe me te haurua o te roangaru kawe o te auau pokapū, ā, ka whakamahia te tikanga whāngai pokapū. Ko te ia tere o te pūihi whatu i te āhua whakapūmau ka whakaatu i te tohatoha ngaru tū. Ko te nuinga o te hihi ka puta mai i ngā taha poto, ko ngā taha roa hei raina tuku. Ka whiwhi te pūihi whatu i te pānga hihi pai ake, ko te hihi mōrahi kei te āhua hihi taha whānui, ā, ko te pōraritanga he whakarara ki te taha poto o te whatu. Ina rerekē te auau mai i te auau pokapū kua hoahoatia, kāore te taha poto o te whatu e haurua i te roangaru aratohu, ā, ka puta te wehenga hihi i roto i te tauira hihi. [2]
Tauira Array me tōna tauira 3D
E ai ki te pikitia o runga ake nei o te hanganga pūihi, ina he 180° te tawhiti o te P1 me te P2 i te āhua, ka taea te whakamahi i te ADS mō te whakatauira kauwhata (kāore i te tauirahia i roto i tēnei tuhinga). Mā te whāngai rerekē i te tauranga whāngai, ka taea te kite i te tohatoha o te iahiko i runga i tētahi huānga whatunga kotahi, e ai ki te tātaritanga matua. Kei ngā ahunga rerekē ngā iahiko i te tūranga roa (whakakorenga), ā, he ōrite te kaha o ngā iahiko i te tūranga whakawhiti, ā, kei roto i te āhua (taupatupatu).
Te tohatoha o nāianei i runga i ngā ringa rerekē1
Te tohatoha o nāianei i runga i ngā ringa rerekē 2
Kei runga ake nei he whakataki poto mō te pūihi whatunga, ā, e hoahoa ana i tētahi rarangi mā te whakamahi i tētahi hanganga whāngai moroiti e mahi ana i te 77GHz. Inaa, e ai ki ngā whakaritenga kimi radar, ka taea te whakaiti, te whakanui rānei i ngā tau poutū me ngā tau whakapae o te whatunga kia tutuki ai he hoahoa pūihi i tētahi koki motuhake. Hei tāpiri, ka taea te whakarerekē i te roa o te raina tuku moroiti i roto i te whatunga whāngai rerekētanga kia tutuki ai te rerekētanga ā-wāhanga e rite ana.
