I tīmata te hītori o ngā pūihi haona i te tau 1897, i te wā i whakahaerehia ai e te kairangahau reo irirangi a Jagadish Chandra Bose ngā hoahoa whakamātautau matua mā te whakamahi i ngā ngaruiti. Nō muri mai, i hangaia e GC Southworth rāua ko Wilmer Barrow te hanganga o te pūihi haona hou i te tau 1938. Mai i taua wā, kua rangahauhia tonutia ngā hoahoa pūihi haona hei whakamārama i ō rātou tauira irahiko me ngā tono i roto i ngā momo mara. He tino rongonui ēnei pūihi i roto i te mara o te tuku arataki ngaru me ngā ngaruiti, nō reira i karangatia ai rātou kongā pūihi ngaruitiNō reira, ka tūhuratia e tēnei tuhinga te mahi a ngā pūihi haona me ā rātou tono i roto i ngā momo mara.
He aha te pūihi haona?
A pūihi pūHe pūihi tuwhera tēnei i hangaia mō ngā auau ngaruiti he pito whānui, he pito āhua haona rānei. Mā tēnei hanganga ka nui ake te aronga o te pūihi, ka taea ai te tuku ngāwari i te tohu i tukuna ki tawhiti. Ko te nuinga o ngā pūihi haona ka mahi i ngā auau ngaruiti, nō reira ko te whānuitanga o te auau he UHF, he EHF rānei.
Pūihi haona RFMISO RM-CDPHA618-20 (6-18GHz)
Ka whakamahia ēnei pūihi hei haona whāngai mō ngā pūihi nunui pērā i ngā pūihi parabolic me ngā pūihi ahunga. Ko ō rātou painga ko te ngāwari o te hoahoa me te whakarerekētanga, te ōwehenga ngaru tū iti, te ahunga taurite, me te whānui o te whānui.
Te hoahoa me te whakahaere i te pūihi haona
Ka taea te whakatinana i ngā hoahoa pūihi haona mā te whakamahi i ngā arataki ngaru āhua-haona hei tuku me te whiwhi i ngā tohu ngaruiti auau reo irirangi. I te nuinga o te wā, ka whakamahia ngātahitia ēnei me ngā whāngai arataki ngaru me ngā ngaru reo irirangi tika hei hanga i ngā hihi whaiti. Ka taea te tae mai te wāhanga whariki i roto i ngā momo āhua, pērā i te tapawhā, te kōniko, te tapawhā tapawhā rānei. Kia tika ai te mahi, me iti te rahi o te pūihi. Mena he tino nui te roanga ngaru, he iti rānei te rahi o te haona, kāore te pūihi e mahi tika.
Te tuhi whakarāpopototanga o te pūihi haona
I roto i te pūihi haona, ka tukuna tetahi wāhanga o te pūngao taupatupatu mai i te tomokanga o te arataki ngaru, ko te toenga o te pūngao ka whakaatahia mai i te tomokanga kotahi nā te mea he tuwhera te tomokanga, ka hua ake he taurite koretake i waenga i te wāhi me te arataki ngaru. Hei tāpiri, i ngā taha o te arataki ngaru, ka pā te diffraction ki te kaha o te arataki ngaru.
Hei whakakore i ngā ngoikoretanga o te arataki ngaru, kua hangaia te whakatuwheratanga pito ki te āhua o te haona hikohiko. Mā tēnei ka taea te whakawhiti maeneene i waenga i te wāhi me te arataki ngaru, ka pai ake te aronga mō ngā ngaru reo irirangi.
Mā te whakarerekē i te arataki ngaru pērā i te hanganga o te haona, ka whakakorea te motumotu me te aukati 377 ohm i waenga i te wāhi me te arataki ngaru. Ka whakarei ake tēnei i te aronga me te whiwhinga o te pūihi tuku mā te whakaiti i te diffraction i ngā taha hei whakarato i te kaha taupatupatu e tukuna ana i te ahunga whakamua.
Anei te mahi a te pūihi pūoro: Kia whakaohokia tetahi pito o te arataki ngaru, ka puta he papa aukume. Mō te horapa o te arataki ngaru, ka taea te whakahaere i te papa horapa mā roto i ngā pakitara arataki ngaru kia kore ai te papa e horapa porowhita engari kia rite ki te horapa o te wāhi wātea. Kia tae te papa whakawhiti ki te pito arataki ngaru, ka horapa pērā i te wāhi wātea, nō reira ka puta he mata ngaru porowhita i te pito arataki ngaru.
