I-RM-SGHA10-25 Standard Gain Horn Antenna ye-75–110 GHz W-Band Applications

Ukusebenza ngokuchanekileyo kokulinganisa i-RF ye-W-Band

Kwi-millimeter-wave frequency, yonke into ekwi-measurement chain ibalulekile. Ukungalingani okuncinci kwe-impedance, iipatheni zemitha ezingazinzanga, okanye izinto ezingafunekiyo ze-polarisation zinokuchaphazela ngokukhawuleza ukuchaneka kovavanyo.I-RF MISOI-RM-SGHA10-25 I-Antenna ye-Standard Gain Hornyenzelwe usetyenziso olupheleleyo75 ukuya kwi-110 GHz, ebonelela ngesisombululo se-antenna esizinzileyo nesijolise kakhulu kwiinjineli ezisebenza kwi-W-band.

Yakhiwe ngeenxa zonkeUjongano lwe-waveguide ye-WR10, i-RM-SGHA10-25 idibanisa ukugubungela okubanzi kunyeInzuzo eqhelekileyo ye-25 dBikwaye1.1:1 i-VSWR eqhelekileyoOlu dibaniso lunceda ekunikezeni udluliselo lwamandla e-RF olufanelekileyo ngelixa lugcina ulwalathiso oluqinileyo kulo lonke uluhlu lokusebenza. I-antenna isebenzisaukuphola okuthe ngqokwaye icacisaUkwahlulwa kwe-cross-polarization ye-50 dB, exhasa imilinganiselo apho ucalucalulo lwe-polarization luyinxalenye ebalulekileyo yokusebenza kwenkqubo.

Ulawulo Oluphezulu Kuyo yonke i-75–110 GHz

I-standard gain horn ibaluleke kakhulu xa indlela esebenza ngayo kwimitha ihlala iqikelelwa njengoko amaza etshintsha. Idatha yokulinganisa ebonelelweyo yeRM-SGHA10-25Ibonisa ukwanda ngokuthe ngcembe kwibhendi, ukusuka kuluhlu oluphakathi lwe-25 dBi kwicala elisezantsi ukuya kwi-27 dBi kufutshane ne-110 GHz.

Le ndlela yokuziphatha ikwabonakala nakwiipateni zemitha.I-75 GHz, 92.5 GHz, kunye ne-110 GHz, iipateni ezilinganisiweyo zigcina umqadi oyintloko ochazwe ngokucacileyo, ngelixa umqadi uba mxinwa njengoko imvamisa isanda. Amaxabiso e-3 dB beawidth abikiweyo abonisa olu qhubekeko, enika iinjineli idatha yesalathiso eluncedo xa kuvavanywa isisombululo se-angular, iimfuno zolungelelwaniso, kunye nejometri yokulinganisa.

Ukubonakaliswa Okuphantsi KweeTyathanga Zokulinganisa Ezicocekileyo

Kwiifrikhwensi ze-W-band, ukuhambelana okuhle kwe-impedance kubaluleke kakhulu kuba ilahleko kunye nokubonakaliswa kunokuchaphazela ngokulula ukungaqiniseki komlinganiselo ngokubanzi.

I-RM-SGHA10-25 ichazwe ngei-VSWR eqhelekileyo ye-1.1:1, kwaye i-simulation curve kwiphepha ledatha ihlala isondelelene nomanyano kulo lonke uluhlu lokusebenza lwe-75–110 GHz. Olu hlobo lokubonakalisa oluphantsi lunceda ukunciphisa iziphumo ezingafunekiyo ze-standing-wave kwaye luvumela amandla amaninzi e-RF afumanekayo ukuba afikelele kwi-antenna aperture.

Kwiiseti zelebhu kunye neenkqubo zovavanyo lwe-millimeter-wave, oku kuthetha ukuba i-antenna ingasebenza njengento ezinzileyo yokurhawuzelela okanye yokwamkela apho ukuphindaphindwa kunye nokuziphatha kwe-RF okulawulwayo kubalulekile.

Ubumsulwa obuqinileyo bokuHlambuluka

Uyilo lwe-linear-polarization ye-antenna luncediswa yi-cross-polarization isolation ephezulu. Uluhlu lweenkcukachaUkwahlulwa kwe-cross-polarization ye-50 dB, ngelixa idatha yokulinganisa ehamba nayo inika ulwazi olongezelelekileyo malunga nocalucalulo lwe-polarisation kulo lonke ibhendi yokusebenza.

Ukuhlukaniswa kwe-polarization ephezulu kubaluleke kakhulu xa iinjineli zifuna ukwahlula i-polarization component efunekayo kumandla angafunekiyo e-orthogonal. Endaweni yokugxila kuphela kwi-gain, olu phawu longezelelweyo lunika umfanekiso opheleleyo wokusebenza kwe-antenna kwiimilinganiselo ze-RF ezichanekileyo.

Incinci, Ilula kwaye Yakhelwe Ukuhlanganiswa kweMillimeter-Wave

Nangona ikwazi ukusebenza rhoqo, i-RM-SGHA10-25 ihlala incinci. Uqwalaselo lohlobo lwe-C lulinganisa malunga82.5 × 26.09 × 33.68 mmkwaye inobunzima kuphela0.03 kgUlwakhiwo lwayo lobhedu oluneukugqitywa ngegolideidibanisa ukuhanjiswa kombane kunye noyilo lobuchwephesha lwecandelo le-millimeter-wave.

Iphepha ledatha likwabonisa zombini i-waveguide/flange kunye noqwalaselo lwe-connector-interface, nto leyo enika iinjineli ukuguquguquka okongezelelweyo xa zidityaniswe i-antenna kwiisetingi ezahlukeneyo ze-RF.

Ngenxa yayoUgutyungelwe yi-75–110 GHz, i-25 dBi eqhelekileyo, i-VSWR ephantsi, ukuhlukaniswa okunamandla kwe-polarisation, kunye noyilo oluncinci lwe-WR10, iRM-SGHA10-25ibonelela ngesisombululo esichanekileyo nesisebenzayo se-gain horn esisemgangathweni se-RF ye-W-band kunye neendawo zokulinganisa i-antenna ezifuna amandla.
