I-Antenna Ejwayelekile Yokuthola Uphondo lwe-RM-SGHA159-10 Yokulinganisa Okuthembekile kwe-RF okungu-4.90–7.05 GHz

Ukulinganiswa kwe-antenna okuthembekile kuqala nge-antenna yokubhekisela enikeza inzuzo ebikezelwayo, ukufana okuzinzile, kanye nezici zokukhanya ezichazwe ngokucacile.RM-SGHA159-10I-Antenna Ejwayelekile Yokuthola Uphondoyenzelwe ukuhlolwa kwe-RF kochwepheshe kulo lonke4.90–7.05 GHzububanzi bemvamisa, enikeza ikhambi elisebenzayo lama-laboratory e-antenna, ukuhlolwa kohlelo lokuxhumana, ukuhlolwa kwe-radar, kanye nezicelo zokulinganisa ama-microwave ezijwayelekile.

Ukusebenza ngeUmhlahlandlela wamagagasi we-WR159, i-RM-SGHA159-10 inikezaInzuzo ejwayelekile engu-10 dBikanye ne-linear polarization. Izici zayo zomsebe olinganiselayo—ngobubanzi obujwayelekile be-3 dB be-beadwidths51.6° ku-E-planefuthi52.1° ku-H-plane—sekela ukukhanya okulawulwayo kanye nokulinganisa okuphindaphindwayo. Lokhu kuziphatha kwemisebe okucishe kube yi-symmetrical kuyasiza kakhulu lapho onjiniyela bedinga ukumbozwa okulinganayo kumabanga e-antenna, amakamelo angenamsindo, noma ukulinganisa inzuzo yokuqhathanisa.

Ukuqhathaniswa okuhle kwe-impedance kubaluleke ngokulinganayo kuchungechunge lokulinganisa.i-VSWR ejwayelekile engu-1.3:1, i-antenna isiza ukunciphisa amandla abonakalayo futhi isekela ukudluliselwa kwesignali okusebenzayo kulo lonke ibhendi yayo yokusebenza. Ama-curve okusebenza eshidini ledatha abonisa impendulo ebushelelezi ye-VSWR kanye nomkhuba wokuzuza okhula kancane kancane kulo lonke ibanga lemvamisa, okunikeza onjiniyela ukuziphatha okuwusizo nokubikezelwayo kwe-broadband.

Ukuze kuhlangatshezwane nezakhiwo ezahlukene zesistimu yokuhlola, i-RM-SGHA159-10 iyatholakala nganoma iyiphiisikhombimsebenzisi se-FDP58 waveguidenomaI-SMA-Female coaxial interfaceInguqulo ye-waveguide ifanelekela ukuhlanganiswa okuqondile nezinhlelo ze-WR159, kuyilapho inguqulo ye-coaxial inikeza uxhumano olulula kumakhebula e-RF avamile, amathuluzi, kanye namapulatifomu okulinganisa.

Ukuguquguquka kokufakwa kungenye inzuzo ewusizo. I-RF MISO inikeza izinketho ezijwayelekile zokufaka uhlobo lwe-L, uhlobo lwe-L olujikelezayo, kanye nohlobo lwe-I. I-bracket ejikelezayo ivumela ukulungiswa kwe-polarization ku-0°, 45°, kanye no-90°, okusiza onjiniyela ukuthi balondoloze ukuhambisana kwe-polarization ngesikhathi sokulinganisa, ukuqhathanisa, kanye nokuhlolwa kwephethini yemisebe.

Yakhiwe nge-aluminium enesiphetho esipendiwe, i-antenna ihlanganisa isakhiwo esilula nokuqina komshini. Inguqulo ye-coaxial-interface iyasekelaAmandla aphakathi angu-150 WfuthiAmandla aphezulu angu-3000 W, kuyilapho ububanzi bokushisa obubekiwe bokusebenza−40°C kuya ku-+85°Civumela ukusetshenziswa kokubili ezindaweni zelebhu kanye nezinhlelo ezidinga kakhulu.

Ngenxa yokuqina kwayo okuzinzile, i-VSWR ephansi, ububanzi be-beammth obulawulwayo, izixhumi eziguquguqukayo, kanye nezinketho zokufaka ezisebenzayo,I-antenna ejwayelekile ye-RM-SGHA159-10 yophondo lokuzuzakuyisinqumo esithembekile sokulinganisa i-antenna, ukuhlanganiswa kwesistimu ye-microwave, ukuqhathanisa inzuzo, ukuhlolwa kwe-radar, kanye nokuhlolwa kwe-C-band RF.
