Ka taea e te pūihi haona takirua-porowhita te tuku me te whiwhi i ngā ngaru hiko porowhita whakapae me te porowhita poutū, me te pupuri tonu i te āhua o te tūranga kia kore e rerekē, kia kore ai e puta te hapa rerekētanga o te tūranga pūnaha i puta mai i te whakarerekētanga o te tūranga pūihi kia tutuki ai ngā whakaritenga o te whakawhiti porowhita, kia taea ai hoki te whakapai ake i te tika o te pūnaha. He painga nui o te pūihi haona takirua-porowhita ko te whakanui nui, te ahunga pai, te wehenga porowhita teitei, te kaha hiko teitei, me ētahi atu, ā, kua whānuitia te rangahau me te whakamahi. Ka taea e te pūihi takirua-porowhita te tautoko i te porowhita raina, te porowhita porowhita me ngā ngaru porowhita porowhita.
Aratau Whakahaere:
| Aratau Whiwhi |
| • Ina whiwhi te pūihi i tētahi ngaru poutū porotaka rārangi, ko te tauranga poutū anake ka taea te whiwhi, ā, ka wehea te tauranga whakapae. • Ina whiwhi te pūihi i tētahi ngaru poutū porotaka rārangi, ko te tauranga whakapae anake ka taea te whiwhi, ā, ka wehea te tauranga poutū. • Ina whiwhi te pūihi i tētahi ngaru porowhita, porowhita rānei, ka whiwhi ngā tauranga poutū me te whakapae i ngā wāhanga poutū me te whakapae o te tohu. I runga i te porowhita maui (LHCP) te porowhita matau rānei (RHCP) o te ngaru, ka 90-tohu te whakaroa, te neke rānei i waenganui i ngā tauranga. Mena he porowhita tino tika te porowhita o te ngaru, ka rite tonu te kaha o te tohu mai i te tauranga. Mā te whakamahi i tētahi hononga ranu tika (90 tohu), ka taea te whakakotahi i te wāhanga poutū me te wāhanga whakapae hei whakaora i tētahi ngaru porowhita, porowhita rānei. |
| Aratau Tuku |
| • Ina whāngaihia te pūihi e tētahi putanga poutū, ka tukuna he ngaru porowhita rārangi poutū. • Ina whāngaihia te pūihi e te tauranga whakapae, ka tukuna e ia te āhua ngaru whakapolarisasi rārangi whakapae. • Ina whāngaihia te pūihi ki ngā tauranga poutū me te whakapae mā te rerekētanga ā-wāhanga 90-tohu, he rite te kaha o te awhe, ka tukuna te ngaru LHCP, RHCP rānei i runga i te whakaroa ā-wāhanga, te neke whakamua rānei i waenga i ngā tohu e rua. Mēnā kāore i te ōrite te kaha o te tohu o ngā tauranga e rua, ka tukuna te ngaru porowhita porowhita. |
| Aratau Whakawhiti |
| • Ina whakamahia te pūihi i te aratau tuku me te aratau whiwhi, nā te wehewehe i waenga i ngā tauranga poutū me te whakapae, ka taea e ia te tuku me te whiwhi i te wā kotahi. |
RF MISOe tuku ana i ngā raupapa e rua o ngā pūihi takirua-polarized, ko tētahi e hangai ana ki te hanganga whā-ridge, ko tētahi e hangai ana ki te Waveguide Ortho-Mode Transducer (WOMT). E whakaaturia ana ēnei i te Pikitia 1 me te Pikitia 2.
Pikitia 1 Pūihi haona porowhita-rua-porowhita
Pikitia 2. Pūihi haona takirua-polarized i runga i te WOMT
Kei te Ripanga 1 ngā āhuatanga ōrite me ngā rerekētanga i waenga i ngā pūihi e rua. I te nuinga o te wā, ka taea e te pūihi i runga i te hanganga whā-tuara te hipoki i te whānuitanga o te whānui o te mahi, he nui ake i te roopu octave, pērā i te 1-20GHz me te 5-50GHz. Mā ngā pūkenga hoahoa tino pai me ngā tikanga tukatuka tino tika,RF MISOKa taea e te pūihi porowhita-rua tino whānui te mahi ki ngā auau teitei o ngā ngaru mirimita. Ko te whānuitanga mahi o ngā pūihi e hangai ana ki te WOMT he mea here e te whānuitanga mahi o te arataki ngaru, engari ko tōna whakanui, te whānui hihi, ngā taha taha me te porowhita whakawhiti/wehenga tauranga-ki-tauranga ka taea te pai ake. I tēnei wā kei te mākete, ko te nuinga o ngā pūihi porowhita-rua e hangai ana ki te WOMT he 20% noa iho o te whānuitanga mahi, ā, kāore e taea te hipoki i te whānuitanga auau arataki ngaru paerewa. Ko te pūihi porowhita-rua e hangai ana ki te WOMT i hangaia eRF MISOka taea te kapi i te roopu auau arataki ngaru katoa, i runga ake rānei i te roopu octave. He maha ngā tauira hei whiriwhiri māu.

He pai te pūihi haona poro-rua-whakakotahi-whā-tuatahi mō ngā tono e horapa ana te whānuitanga ine i ngā roopu auau arataki-ngaru maha, ā, he painga anō hoki o te whānuitanga whānui-rahi me te whakamātautau tere. Mō ngā pūihi poro-rua-whakakotahi i runga i te WOMT, ka taea e koe te whiriwhiri i ngā momo pūihi rerekē, pērā i te haona kōniko, te haona piramita, te tirotiro arataki-ngaru tuwhera, te haona arotahi, te haona tauine, te haona kowakawaka, te haona whāngai kowakawaka, te pūihi Gaussian, te pūihi rihi, me ētahi atu. He maha ngā pūihi e tika ana mō tētahi tono pūnaha.RF MISOka taea te whakarato i tētahi kōwae whakawhiti arataki ngaru porowhita ki te tapawhā hei whakatū hononga tika i waenga i tētahi pūihi me te atanga arataki ngaru porowhita paerewa me tētahi WOMT me te atanga arataki ngaru tapawhā. Ko ngā pūihi haona pōro-rua e hangai ana ki te WOMT eRF MISOka taea te whakarato kei te whakaatuhia i te Ripanga 2.
