ʻAntenna Horn Gain Maʻamau RM-SGHA10-25 no nā noi W-Band 75–110 GHz

Hana Kūpono no ke Ana ʻana o ka W-Band RF

Ma nā alapine nalu millimeter, he mea nui kēlā me kēia ʻāpana i ke kaulahao ana. ʻO nā mismatch impedance liʻiliʻi, nā ʻano radiation paʻa ʻole, a i ʻole nā ​​​​ʻāpana polarization makemake ʻole ʻia e hiki ke hoʻopilikia koke i ka pololei o ka hoʻāʻo.RF MISOAntenna Pepeiao Loaʻa Maʻamau RM-SGHA10-25ua ʻenehana ʻia no nā noi ma nā ʻaoʻao75 a i 110 GHz, e hāʻawi ana i kahi hopena antenna paʻa a kuhikuhi pono hoʻi no nā ʻenekinia e hana ana ma ka W-band.

Kūkulu ʻia a puni kahiʻO ka pilina alakaʻi nalu WR10, hoʻohui ka RM-SGHA10-25 i ka uhi alapine ākea me25 dBi loaʻa maʻamaua me1.1:1 VSWR maʻamau. Kōkua kēia hui pū ʻana i ka hāʻawi ʻana i ka hoʻoili ikehu RF kūpono me ka mālama ʻana i ka kuhikuhi ikaika ma waena o ka laulā hana. Hoʻohana ka antennaka polarization lineara kuhikuhi50 dB ka hoʻokaʻawale ʻana o ke cross-polarization, e kākoʻo ana i nā ana kahi i lilo ai ka hoʻokae polarization i ʻāpana koʻikoʻi o ka hana o ka ʻōnaehana.

Kuhikuhi Kiʻekiʻe ma waena o 75–110 GHz

ʻOi aku ka waiwai o ka pepeiaohao loaʻa maʻamau ke mau ka wānana ʻana i kāna ʻano radiation i ka wā e loli ai ke alapine (frequency). ʻO ka ʻikepili simulation i hāʻawi ʻia no kaRM-SGHA10-25hōʻike i ka piʻi mau ʻana o ka loaʻa ma ke kāʻei, mai kahi o waena o 25 dBi ma ka ʻaoʻao haʻahaʻa a i ʻoi aku ma mua o 27 dBi kokoke i 110 GHz.

Hōʻike ʻia kēia ʻano kuhikuhi i nā ʻano radiation.75 GHz, 92.5 GHz, a me 110 GHz, mālama nā ʻano hoʻohālike i kahi kukuna nui i wehewehe pono ʻia, ʻoiai e lilo ka kukuna i mea haiki i ka piʻi ʻana o ke alapine (frequency). Hōʻike nā waiwai beamwidth 3 dB i hōʻike ʻia i kēia holomua, e hāʻawi ana i nā ʻenekinia me ka ʻikepili kuhikuhi pono i ka wā e loiloi ai i ka hoʻonā angular, nā koi hoʻonohonoho, a me ke geometry ana.

ʻIke Haʻahaʻa no nā Kaulahao Ana Maʻemaʻe

Ma nā alapine (frequencies) W-band, lilo ka hoʻohālikelike impedance maikaʻi i mea nui loa no ka mea hiki i nā pohō a me nā noʻonoʻo ʻana ke hoʻololi maʻalahi i ka maopopo ʻole o ke ana holoʻokoʻa.

Ua kuhikuhi ʻia ka RM-SGHA10-25 me kahiʻO ka VSWR maʻamau o 1.1:1, a ʻo ke kiʻikuhi hoʻohālike i loko o ka pepa ʻikepili e noho kokoke ana i ka hoʻokahi ma o ka pae hana 75-110 GHz. Kōkua kēia ʻano noʻonoʻo haʻahaʻa i ka hōʻemi ʻana i nā hopena nalu kū i makemake ʻole ʻia a ʻae i ka nui o ka mana RF i loaʻa e hiki i ka puka antenna.

No nā hoʻonohonoho hoʻokolohua a me nā ʻōnaehana hoʻāʻo nalu millimeter, ʻo ia hoʻi hiki i ka antenna ke lawelawe ma ke ʻano he mea hoʻomālamalama paʻa a i ʻole mea loaʻa kahi e nui ai ka hana hou ʻana a me ka hana RF i kāohi ʻia.

Ka Maʻemaʻe Polarization Ikaika

Ua hoʻokō ʻia ka hoʻolālā linear-polarization o ka antenna e ka hoʻokaʻawale cross-polarization kiʻekiʻe. Papa inoa kikoʻī50 dB ka hoʻokaʻawale ʻana o ke cross-polarization, ʻoiai ʻo ka ʻikepili simulation e hele pū ana e hāʻawi i ka ʻike hou aku i ka hoʻokaʻawale polarization ma waena o ke kāʻei hana.

He mea waiwai nui ka hoʻokaʻawale polarization kiʻekiʻe i ka wā e pono ai nā ʻenekinia e hoʻokaʻawale i ka ʻāpana polarization i makemake ʻia mai ka ikehu orthogonal i makemake ʻole ʻia. Ma mua o ka nānā wale ʻana i ka loaʻa, hāʻawi kēia ʻano hou i kahi kiʻi piha o ka hana antenna i nā ana RF pololei.

Paʻa, Māmā a Kūkulu ʻia no ka Hoʻohui Milimita-Nalu

ʻOiai kona hiki ke hoʻolohe pinepine kiʻekiʻe, ua noho paʻa ka RM-SGHA10-25. ʻO ke ana o ke ʻano C ma kahi o82.5 × 26.09 × 33.68 mma kaupaona wale nō0.03 kgʻO kona kūkulu keleawe me kahihoʻopau gulahoʻohui i ka conductivity uila me kahi hoʻolālā ʻāpana millimeter-wave ʻoihana.
