Ariā Pūihi – Te Pūihi Whakapiko Haurua-Ngaru
Ko te pūihi he pūihi e rua ngā ara iahiko whakarara e honoa ana i ngā pito e rua, e hanga ana i tētahi hanganga porowhita kati, me te pūwāhi whāngai kei waenganui. Ko te roa katoa o te pūihi he haurua o te roangaru, koia i huaina ai hoki ko te haurua-ngaru kua takai...Pānuihia atu -
Ariā Pūihi – Te Pūrua-Ngaru-Haurua
Ka tapahia, ka pikohia te pūihi dipole hei whakatutuki i te irahiko whai hua. Ko te roa katoa o te waea e whakamahia ana hei dipole he rite ki te haurua o te roanga ngaru (arā, l=λ/2). Ka kiia tēnei momo pūihi he antenna dipole haurua-ngaru. Nā ōna painga, koinei te antenna e whakamahia whānuitia ana...Pānuihia atu -
Ariā Pūihi – Waea
Ko ngā pūihi waea tētahi o ngā momo pūihi taketake. He mea rongonui, ā, he whānui te whakamahinga. Hei mārama ake ki ngā pūihi waea, me titiro tuatahi tātou ki te raina tuku. Raina Tuku He raina tuku, he waea rānei, e kawe ana i te pūngao hiko mai i...Pānuihia atu -
Ariā Pūihi – Te Wetereo Poynting
Ka tukuna, ka whiwhi rānei ngā pūihi i ngā kōrero mā te tuku i te pūngao hikohiko. Nō reira, ko te pūngao me te mana ngā tawhā matua e pā ana ki ēnei ngaru hikohiko, ā, he mea nui kia matapakihia ēnei. Kei roto i te ngaru hikohiko he papa hiko me te...Pānuihia atu -
Ariā Pūihi – Whānuitanga Hiko
I roto i te tauira irahiko o te pūihi, ko te pū matua te tohu o te hihi matua o te pūihi, e tukuna atu ai te pūngao mōrahi me te tino kukū. Ko te whānui hihi te whānui koki o te kōhao e tukuna atu ai te nuinga o te mana. Ko ngā hihi matua e rua ...Pānuihia atu -
Ariā Pūihi – Ngā Hiko me te Whakapūtanga
E matapakihia ana i tēnei upoko ngā tawhā o ngā hihi irahiko o te pūihi, hei āwhina i a tātou ki te mārama ki ngā whakatakotoranga hihi. Te Horahanga Hira E ai ki te whakamāramatanga paerewa: "Mēnā ka noho tonu te kaha hihi P(θ,ϕ) ki tōna uara mōrahi i runga ake i...Pānuihia atu -
Ariā Pūihi — Irahiko Irahiko
I te upoko o mua, i kōrerohia e tātou ngā tauira irahiko. Hei tātari pai ake i te irahiko pūihi, me whai i tētahi pūwāhi tohutoro. Ko te irahiko o tētahi pūihi isotropic te mea e tutuki ai tēnei mahi. Whakamāramatanga Ko te irahiko isotropic e pā ana ki te irahiko mai i tētahi pūtake pūwāhi...Pānuihia atu -
Ariā Pūihi – Ngā Tauira Irahiko
Ko te irahiko he kupu e whakaahua ana i te kaha o ngā ngaru hikohiko e tukuna ana, e whiwhihia ana rānei e te pūihi. I roto i ngā whakaahua katoa o te pūihi, ko te hoahoa e whakaatu ana i ngā āhuatanga irahiko o te pūihi e mōhiotia ana ko tōna tauira irahiko. Mā te mātakitaki i te irahiko p...Pānuihia atu -
Ariā Pūihi – Papa Tata me Papa Tawhiti
Whai muri i te matapakinga o ngā tawhā pūihi taketake i te upoko o mua, ko tētahi atu kaupapa nui hei whakaaroaro ko ngā rohe tata-papa me ngā rohe tawhiti-papa o te pūihi. He rerekē te kaha o te irahiko e inehia ana i te taha tata o te pūihi i tērā e inehia ana i tawhiti. ...Pānuihia atu -
Ariā Pūihi – Ngā Tawhā Taketake
Ka whakaurua e tēnei upoko ngā tawhā matua o te whakawhitiwhiti kōrero ahokore, e whai ana kia pai ake te māramatanga ki te tūranga o ngā pūihi i roto i ngā pūnaha whakawhitiwhiti kōrero. Ka whakahaerehia te whakawhitiwhiti kōrero ahokore i roto i te āhua o ngā ngaru hikohiko, nā reira he mea nui kia mārama...Pānuihia atu -
Te Aratohu Tino Pai ki ngā Antenna: Te Mahi a ngā Antenna
He taputapu whakawhitiwhiti kōrero noa ngā pūihi i roto i ō tātou ao. Heoi, kāore te nuinga o te tangata e tino mārama ki a rātou, e mōhio ana pea rātou he mea whakamahi hei tuku me te whiwhi tohu. Heoi anō, mai i te wa i angitu ai te hanga a te kaipūtaiao Rūhia, a Popov, i te pūihi i te tau 18...Pānuihia atu -
AESA vs PESA: Te Hurihanga o ngā Hoahoa Pūihi Hou ki ngā Pūnaha Radar
Ko te whanaketanga mai i te Passive Electronically Scanned Array (PESA) ki te Active Electronically Scanned Array (AESA) te whanaketanga nui rawa atu o te hangarau radar hou. Ahakoa e whakamahi ana ngā pūnaha e rua i te urungi hihi hiko, he rerekē ngā hanganga taketake...Pānuihia atu
