Pūihi miroitihe momo ngaruiti houpūihie whakamahi ana i ngā rīpene arataki kua tāia ki runga i tētahi papa hiko-kore hei waeine whakawhiti antenna. Kua whānuitia te whakamahinga o ngā antenna rīpene iti i roto i ngā pūnaha whakawhitiwhiti kōrero hou nā te iti o te rahi, te māmā, te iti o te kōtaha, me te ngāwari o te whakauru.
Te mahi a te pūihi microstrip
Ko te kaupapa mahi o te pūihi microstrip e hangai ana ki te tuku me te irahiko o ngā ngaru hikohiko. Ko te tikanga he papa irahiko, he papa dielectric me te pereti whenua. Ka tāia te papa irahiko ki te mata o te papa dielectric, ko te pereti whenua kei tera taha o te papa dielectric.
1. Pātaki irahiko: He wāhanga nui te pātaki irahiko o te pūihi moroiti. He pātaki whakarewa angiangi e hopu ana, e tuku ana hoki i ngā ngaru hikohiko.
2. Papa whakakāhikohiko: Ko te papa whakakāhikohiko he mea hanga i ngā rauemi iti-ngaronga, teitei-pūmau-whakakāhiko, pērā i te polytetrafluoroethylene (PTFE) me ētahi atu rauemi uku. Ko tana mahi he tautoko i te papa irahiko me te mahi hei reo mō te horapa o ngā ngaru hikohiko.
3. Pereti whenua: Ko te pereti whenua he paparanga whakarewa nui ake kei tera taha o te papa dielectric. Ka hanga hononga capacitive ki te papa irahiko, ā, ka whakarato i te tohatoha mara hikohiko e tika ana.
Ina tukuna te tohu ngaruiti ki roto i te pūihi moroiti, ka hangaia he ngaru tū i waenganui i te papa irahiko me te pereti whenua, ka puta he irahiko o ngā ngaru hikohiko. Ka taea te whakarite i te whai huatanga me te tauira o te pūihi moroiti mā te whakarerekē i te āhua me te rahi o te papa me ngā āhuatanga o te papa dielectric.

Te rerekētanga i waenga i te pūihi microstrip me te pūihi patch
Ko te pūihi papaki he momo pūihi moroiti, engari he rerekētanga kei waenganui i te hanganga me te mātāpono mahi:
1. Ngā rerekētanga hanganga:
Pūihi iti-whiri: he maha ngā wā ka hangaia he papa irahiko, he papa whakapūngao hiko me he pereti whenua. Ka whakairihia te papa ki runga i te papa whakapūngao hiko.
Pūihi papaki: Ko te wāhanga hihi o te pūihi papaki e piri tika ana ki te papa hiko-kore, kāore he hanganga iri e kitea ana.
2. Tikanga whāngai:
Pūihi riipene iti: Ko te tikanga ka honoa te whāngai ki te wāhi hihi mā roto i ngā tirotiro, i ngā aho riipene iti rānei.
Antenna papaki: He rerekē ngā tikanga whāngai, arā, ko te whāngai taha, te whāngai mokowā, te whāngai papatahi rānei, me ētahi atu.
3. Te whai huatanga o te irahiko:
Pūihi iti-ira: Nā te mea he āputa kei waenganui i te papa irahiko me te pereti whenua, tera pea ka ngaro te āputa hau, ka pā ki te whai huatanga o te irahiko.
Pūihi papaki: Ko te huānga hihi o te pūihi papaki he mea hono tata ki te papa whakapūmau hiko, he nui ake te pai o te hihi.
4. Te mahi whānui o te hononga:
Pūihi iti-whiri: He whaiti te whānui o te hononga, ā, me whakanui ake te whānui o te hononga mā te hoahoa kua arotauhia.
Antenna papaki: Ka taea te whakatutuki i te whānui o te whānui mā te hoahoa i ngā hanganga rerekē, pērā i te tāpiri i ngā rara radar, te whakamahi rānei i ngā hanganga paparanga-maha.
5. Ngā wā tono:
Pūihi iti-ripanga: he pai mō ngā tono he tino whakaritenga mō te teitei o te kōtaha, pērā i ngā whakawhitiwhitinga amiorangi me ngā whakawhitiwhitinga pūkoro.
Ngā pūihi papaki: Nā te kanorau o te hanganga, ka taea te whakamahi i roto i te whānuitanga o ngā tono, tae atu ki te radar, ngā LAN ahokore, me ngā pūnaha whakawhitiwhiti kōrero whaiaro.
Hei whakamutunga
He mea whakamahi whānuitia ngā pūihi moroiti me ngā pūihi papaki hei pūihi ngaruiti i roto i ngā pūnaha whakawhitiwhiti kōrero hou, ā, he āhuatanga me ngā painga anō ō rāua. He tino pai ngā pūihi moroiti i roto i ngā tono he iti te wāhi nā te mea he iti te kōtaha me te ngāwari o te whakauru. Ko ngā pūihi papaki, i tētahi atu taha, he mea noa ake i roto i ngā tono e hiahia ana ki te whānui o te whānui me te tino pai o te mahi nā te mea he nui te pai o te irahiko me te hoahoa.
