I-Antenna ye-RM-SGHA10-25 Standard Gain Horn yezinhlelo zokusebenza ze-W-Band ezingu-75–110 GHz

Ukusebenza Okunembile Kokulinganisa I-RF Yebhendi Ye-W

Kumaza e-millimeter-wave, yonke ingxenye eketangeni lokulinganisa ibalulekile. Ukungafani okuncane kwe-impedance, amaphethini emisebe angazinzile, noma izingxenye ze-polarisation ezingafuneki kungathinta ngokushesha ukunemba kokuhlolwa.I-RF MISOI-Antenna ye-RM-SGHA10-25 Standard Gain Hornyenzelwe izinhlelo zokusebenza kuzo zonke75 kuya ku-110 GHz, enikeza isixazululo se-antenna esizinzile nesiqondisa kakhulu konjiniyela abasebenza ku-W-band.

Yakhelwe eduzeisikhombimsebenzisi se-WR10 waveguide, i-RM-SGHA10-25 ihlanganisa ukumbozwa kwemvamisa ebanzi kanyeInzuzo ejwayelekile engu-25 dBifuthi1.1:1 i-VSWR ejwayelekile. Le nhlanganisela isiza ekuletheni ukudluliselwa kwamandla e-RF okuphumelelayo ngenkathi kugcinwa isiqondiso esinamandla kulo lonke uhla lokusebenza. I-antenna isebenzisaukwahlukana okuqondilefuthi icacisaUkuhlukaniswa kwe-cross-polarization okungu-50 dB, esekela izilinganiso lapho ukuhlukaniswa kwe-polarization kuyingxenye ebalulekile yokusebenza kwesistimu.

Ukuqondisa Okuphezulu Kuyo yonke i-75–110 GHz

I-standard gain horn ibaluleke kakhulu uma ukuziphatha kwayo kwemisebe kuhlala kubikezelwa njengoba imvamisa ishintsha. Idatha yokulingisa enikeziwe yeRM-SGHA10-25imibukiso iyanda kancane kancane kulo lonke ibhendi, kusukela cishe kububanzi obuphakathi kwama-dBi angu-25 ekugcineni okuphansi kuya ku-dBi engaphezu kwama-27 eduze kwe-110 GHz.

Lokhu kuziphatha kokuqondisa kubonakala futhi emaphethini emisebe.75 GHz, 92.5 GHz, kanye ne-110 GHz, amaphethini alingisiwe agcina umsebe oyinhloko ochazwe ngokucacile, kuyilapho umsebe uba mncane njengoba imvamisa ikhuphuka. Amanani abikiwe angu-3 dB beawidth abonisa lokhu kuqhubeka, enikeza onjiniyela idatha ewusizo yokubhekisela lapho behlola isixazululo se-angular, izidingo zokuqondanisa, kanye ne-geometry yokulinganisa.

Ukuzindla Okuphansi Kwamaketanga Okulinganisa Okuhlanzekile

Kumaza e-W-band, ukufanisa okuhle kwe-impedance kuba kubaluleke kakhulu ngoba ukulahlekelwa kanye nokuzindla kungathinta kalula ukungaqiniseki kokulinganisa okuphelele.

I-RM-SGHA10-25 ichazwe nge-i-VSWR ejwayelekile engu-1.1:1, futhi ijika lokulingisa kushidi ledatha lihlala liseduze nobunye kulo lonke ibanga lokusebenza le-75–110 GHz. Lokhu kuziphatha kokubonisa okuphansi kusiza ukunciphisa imiphumela engafuneki yamagagasi okuma futhi kuvumela amandla e-RF amaningi atholakalayo ukuthi afinyelele ekuvulekeni kwe-antenna.

Ngokusethwa kwelabhorethri kanye nezinhlelo zokuhlola amagagasi e-millimeter, lokhu kusho ukuthi i-antenna ingasebenza njengento ezinzile ekhipha imisebe noma eyamukelayo lapho ukuphindaphindeka nokuziphatha kwe-RF okulawulwayo kubalulekile.

Ukuhlanzeka Okuqinile Kokuhlukaniswa

Umklamo we-linear-polarization we-antenna uhambisana nokuhlukaniswa okuphezulu kwe-cross-polarization. Uhlu lwezincazeloUkuhlukaniswa kwe-cross-polarization okungu-50 dB, kuyilapho idatha yokulingisa ehambisanayo inikeza ukuqonda okwengeziwe ngokubandlululwa kwe-polarization kulo lonke ibhendi yokusebenza.

Ukuhlukaniswa okuphezulu kwe-polarization kubaluleke kakhulu lapho onjiniyela bedinga ukuhlukanisa ingxenye ye-polarization efiselekayo kumandla angafuneki e-orthogonal. Esikhundleni sokugxila ekuzuzeni kuphela, lesi sici esengeziwe sinikeza isithombe esiphelele sokusebenza kwe-antenna ekulinganisweni kwe-RF okunembile.

Incane, Ilula Futhi Yakhelwe Ukuhlanganiswa Kwe-Millimeter-Wave

Naphezu kokwazi kwayo ukusebenza ngesivinini esiphezulu, i-RM-SGHA10-25 ihlala incane. Ukucushwa kohlobo lwe-C kulinganisa cishe82.5 × 26.09 × 33.68 mmfuthi inesisindo kuphela0.03 kgUkwakhiwa kwayo ngethusiukuqeda okumbozwe ngegolideihlanganisa ukuhanjiswa kukagesi nomklamo wezingxenye zamagagasi angamamilimitha ochwepheshe.

Ishidi ledatha liphinde libonise kokubili umhlahlandlela wamagagasi/i-flange kanye nokulungiselelwa kwesixhumi-isikhombimsebenzisi, okunikeza onjiniyela ukuguquguquka okwengeziwe lapho behlanganisa i-antenna kumasethingi e-RF ahlukene.

NgayoUkumbozwa okungu-75–110 GHz, inzuzo ejwayelekile engu-25 dBi, i-VSWR ephansi, ukuhlukaniswa okunamandla kwe-polarization, kanye nokwakheka kwe-WR10 okuhlanganisiwe, iRM-SGHA10-25inikeza isisombululo esijwayelekile esinembile nesisebenzayo se-gain horn sezindawo zokulinganisa i-W-band RF kanye ne-antenna ezifunwayo.
