Ma ke kahua o nā mea hoʻoheheʻe electromagnetic, huikau pinepine nā antenna RF a me nā antenna microwave, akā aia nā ʻokoʻa kumu. Ke alakaʻi nei kēia ʻatikala i ka loiloi ʻoihana mai ʻekolu mau ʻāpana: ka wehewehe ʻana i ka band frequency, ka loina hoʻolālā, a me ke kaʻina hana hana, ʻoi aku ka hoʻohui ʻana i nā ʻenehana koʻikoʻi e like mehoʻopaʻa haʻahaʻa.
RF MISOUhi Puhi Puhi
1. Ka laula o ka bana alapine a me na ano kino
Antenna RF:
ʻO 300 kHz - 300 GHz ka pā alapine hana, e uhi ana i ka hoʻolaha hawewe waena (535-1605 kHz) a i ka nalu millimeter (30-300 GHz), akā ʻo nā noi kumu i hoʻopaʻa ʻia ma <6 GHz (e like me 4G LTE, WiFi 6). ʻOi aku ka lōʻihi o ka nalu (kenimika a i ka pae mika), ʻo ke ʻano o ka dipole a me ka antenna whip, a haʻahaʻa ka naʻau i ka hoʻomanawanui (± 1% ka lōʻihi o ka nalu.
Antenna microwave:
ʻOi aku ka 1 GHz - 300 GHz (ka nalu millimeter a me ka nalu millimeter), nā pūnaʻi alapine noi maʻamau e like me X-band (8-12 GHz) a me Ka-band (26.5-40 GHz). Nā koi no ka lōʻihi hawewe pōkole (pae millimeter):
✅ Ka pololei o ka hoʻoili ʻana i ka pae submillimeter (ka hoʻomanawanui ≤±0.01λ)
✅ Ka hoʻomalu ʻana i ka ʻeleʻele ʻili (<3μm Ra)
✅ Pāpaʻa dielectric pohō haʻahaʻa (ε r ≤2.2, tanδ≤0.001)
2. ʻO ka wai o ka ʻenehana hana
ʻO ka hana o nā antenna microwave e hilinaʻi nui ʻia i ka ʻenehana hana kiʻekiʻe:
| ʻenehana | RF Antenna | Antenna Microwave |
| ʻenehana hoʻohui | Hoʻopaʻa ʻia ʻana/hoʻopaʻa ʻana | Puhi Puhi |
| Nā mea hoʻolako maʻamau | Hale Hana Uila Nui | ʻO nā hui Brazing e like me Solar Atmospheres |
| Koi wiliwili | Hoʻopili conductive | ʻO ke komo ʻana o ka oxygen zero, ka hoʻonohonoho hou ʻana o ka palaoa |
| Nā Ana Nui | Kū'ē <50mΩ | Hoʻohālikelike ʻia ka helu hoʻonui wela (ΔCTE<1ppm/℃) |
ʻO ka waiwai nui o ka vacuum brazing i nā antenna microwave:
1. Oxidation-free pilina: brazing i loko o ka 10 -5 Torr vacuum kaiapuni e pale aku oxidation o Cu/Al alloys a malama conductivity>98% IACS
2. Hoʻopau i ke koʻikoʻi wela: ka hoʻomehana ʻana i ka gradient ma luna o ka wai o ka mea hoʻoheheʻe ʻia (e laʻa me BAISi-4 alloy, liquidus 575 ℃) e hoʻopau i nā microcracks
3. Ka hoʻoponopono hoʻololi: ka hoʻololi holoʻokoʻa <0.1mm/m e hōʻoia i ka paʻa ʻana o ka pae millimeter.
3. Hoʻohālikelike i ka hana uila a me nā hiʻohiʻona noi
ʻO nā hiʻohiʻona hoʻomālamalama:
1.RF antenna: ka nui omnidirectional radiation, loaʻa ≤10 dBi
2.Antenna Microwave: kuhikuhi nui loa (ka laula o ka beam 1°-10°), loaʻa 15-50 dBi
Nā noi maʻamau:
| RF Antenna | Antenna Microwave |
| hale lekiō FM | Nā ʻāpana T/R Radar Array Phased |
| Nā mea ʻike IoT | hānai kamaʻilio Satellite |
| RFID Tags | 5G mmWave AAU |
4. E ho'āʻo i nā ʻokoʻa hōʻoia
Antenna RF:
- Nānā: Hoʻohālikelike impedance (VSWR <2.0)
- Ke Kaʻina Hana: Holoi pinepine ʻana i ka mea hōʻike pūnaewele Vector
Antenna microwave:
- Manaʻo: ʻO ke ʻano o ka hoʻoheheʻe ʻana/ke ʻano kūlike
- Ke Kaʻina Hana: Ma kahi kokoke i ka mākaʻikaʻi kahua (pololei λ/50), hoʻāʻo kahua paʻa
ʻO ka hopena: ʻO nā antenna RF ka pōhaku kihi o ka hoʻohui ʻana i ke kelepona ākea, ʻoiai ʻo nā antenna microwave ke kumu o nā ʻōnaehana kiʻekiʻe a me nā ʻōnaehana kiʻekiʻe. ʻO ka wai ma waena o nā mea ʻelua:
1. ʻO ka hoʻonui ʻana i ke alapine e alakaʻi i kahi lōʻihi hawewe pōkole, e hoʻoulu i kahi hoʻololi paradigm i ka hoʻolālā
2. Hoʻololi kaʻina hana - hilinaʻi nā antenna microwave i nā ʻenehana ʻokiʻoki e like me ka vacuum brazing e hōʻoia i ka hana.
3. Piʻi nui ka paʻakikī hoʻāʻo
ʻO nā hoʻonā ʻana o ka vacuum brazing i hāʻawi ʻia e nā ʻoihana brazing ʻoihana e like me Solar Atmospheres ua lilo i mea hōʻoia nui no ka hilinaʻi o nā ʻōnaehana nalu millimeter. I ka hoʻonui ʻana o 6G i ka band frequency terahertz, e ʻoi aku ka nui o ka waiwai o kēia kaʻina hana.
No ka ʻike hou aku e pili ana i nā antenna, e kipa:
