I-Log Spiral Antenna 8 dBi Uhlobo Lokuthola, Ibanga Lokuphindaphindeka Eliyi-1-12 GHz RM-LSA112-8R

I-Log Spiral Antenna 8 dBi Uhlobo Lokuzuza, Ibanga Lemvamisa Eliyi-1-12 GHz RM-LSA112-8R Isithombe Esifakiwe

Incazelo emfushane:

Imodeli ye-RF MISO i-RM-LSA112-8R iyi-antenna ejikelezayo ejikelezayo ejikelezayo esebenza kusukela ku-1-12GHz. I-antenna inikeza uhlobo lwe-gain 8 dBi kanye ne-VSWR ephansi <2.5 enesixhumanisi se-SMA-Female. Yenzelwe ngqo izinkambu ezinezidingo eziphezulu kakhulu ze-bandwidth kanye nokuguquguquka kwe-polarization, njengokuhlola nge-elekthronikhi, ukuhlolwa kwe-EMC, kanye nokuxhumana kwe-broadband.

I-antenna ye-log-spiral iyi-antenna ye-angular yakudala enemingcele yengalo yensimbi echazwa ngama-logarithmic spiral curves. Nakuba ifana ngokubonakalayo ne-Archimedean spiral, isakhiwo sayo esiyingqayizivele sezibalo senza kube "yi-antenna engaxhomekile kumaza."

Ukusebenza kwayo kuncike esakhiweni sayo esihambisanayo (izikhala zensimbi nomoya ziyafana ngesimo) kanye nohlobo lwayo oluyi-angular kuphela. Indawo esebenzayo ye-antenna ku-frequency ethile iyindawo emise okwendandatho enomjikelezo ongaba yi-wavelength eyodwa. Njengoba i-frequency yokusebenza ishintsha, le ndawo esebenzayo ihamba kahle ezingalweni ezijikelezayo, kodwa isimo sayo kanye nezici zikagesi zihlala zinjalo, okuvumela i-bandwidth ebanzi kakhulu.

Izinzuzo ezibalulekile zale antenna ukusebenza kwayo kwe-ultra-wideband (ama-bandwidth angu-10:1 noma ngaphezulu avamile) kanye nekhono layo elingokwemvelo lokukhipha amagagasi ahlukaniswe ngendilinga. Izithiyo zayo eziyinhloko ukutholakala okuphansi kanye nesidingo senethiwekhi yokuphakelayo elinganiselayo eyinkimbinkimbi. Isetshenziswa kabanzi ezinhlelweni zokusebenza ezidinga ukusebenza kwe-wideband, njenge-Electronic Countermeasures (ECM), ukuxhumana kwe-broadband, kanye nezinhlelo zokuqapha i-spectrum.
