Iimveliso ze-RFMISOCircular Polarization Horn Antenna

Imbali ye-antenna yophondo olujikelezileyo olune-polarized

I-antenna ye-circularly polarized horn luhlobo olubalulekileyo lwe-antenna oluneendlela ezahlukeneyo zokusetyenziswa, kubandakanya unxibelelwano, i-radar, unxibelelwano lwesathelayithi kunye nokulinganisa irediyo. Oku kulandelayo yintshayelelo yembali kwii-antenna ze-circularly polarized horn:

Ukususela ekupheleni kweminyaka yoo-1940 ukuya ekuqaleni kweminyaka yoo-1950, kwaqala ukubonakala ingcamango kunye noyilo lwee-antenna ze-horn ezijikelezileyo ezijikelezileyo. Ngeli xesha, iinjineli ze-antenna zaqala ukuqonda ukuba ii-antenna zendabuko ezijikelezileyo ezijikelezileyo zinemida kwimisebenzi ethile. Ngoko ke, baqala ukuphanda nokuphonononga ingcamango yee-antenna ezijikelezileyo ezijikelezileyo ukuze bafumane ukusebenza okungcono kokuhambisa isignali kunye nokwamkela.

Ngo-1958, uPaul G. Montgomery, injineli kwiRadar Systems Corporation eMelika, wayila i-antenna ye-horn eneempawu ze-circular polarization, ebizwa ngokuba yiMontgomery Antenna. Le yayiyeyokuqala ukuphunyezwa ngempumelelo kwe-antenna ye-circularly polarized horn kwaye yatsala ingqalelo enkulu kunye nophando.

Kwiminyaka emashumi alandelayo, ii-antenna zeempondo ezijikelezileyo ziye zaphandwa kwaye zaphuhliswa. Iinjineli zenze uvavanyo olubanzi kunye nohlalutyo lwethiyori ekuyileni nasekuphuculeni ulwakhiwo kunye nokusebenza kwee-antenna zeempondo ezijikelezileyo.

Kwiminyaka yoo-1960, ii-antenna ze-horn ezijikelezileyo nezine-polarized zazisetyenziswa kakhulu kwicandelo lonxibelelwano. Inzuzo ye-antenna ye-horn ejikelezileyo kukuba inokufikelela kwi-signal coverage engcono kunye nokukwazi ukulwa nokuphazamiseka, kwaye ifanelekile ngakumbi kwiindawo zokusasaza ngeendlela ezininzi kwiinkqubo zonxibelelwano ezingenazingcingo.

Kwiminyaka yoo-1980 noo-1990, ngophuhliso olongezelelekileyo lonxibelelwano lwesathelayithi kunye netekhnoloji yeradar, uluhlu lokusetyenziswa kwee-antenna ze-horn ezijikelezileyo zandiswa ngakumbi. Ii-antenna ze-horn ezijikelezileyo zisetyenziswa kakhulu kwizikhululo zomhlaba zonxibelelwano lwesathelayithi, kwiinkqubo zeradar, nakwiindawo zomkhosi nezomoya.

Ngokuqhubeka nokuqhubela phambili kwetekhnoloji ye-elektroniki, uyilo kunye nenkqubo yokuvelisa ii-antenna ze-horn ezijikelezileyo nezine-polarized nazo ziye zaphuculwa. Ii-antenna ze-horn ezijikelezileyo nezine-polarized zanamhlanje zisebenzisa izixhobo eziphambili kunye neendlela zokwenza ukubonelela ngamaza aphezulu okusebenza, ukusebenza okungcono kunye nobukhulu obuncinci.

Isebenza njani i-antenna yephondo ejikelezileyo e-polarized

Ii-antenna zephondo ezijikelezileyo ezijikelezileyo zifumana iimpawu zemitha ezijikelezileyo ezijikelezileyo ngokuyintloko ngejometri yazo ekhethekileyo kunye noyilo. Umgaqo wokusebenza wale antenna usekelwe kwezi mpawu zilandelayo ziphambili:

Imilo yephondo: Ii-antenna zephondo ezijikelezileyo ezijikelezileyo zihlala zinesakhiwo se-radiator esimile okwephondo. Uyilo lwe-antenna yephondo lubangela ukuba isignali isasazeke rhoqo ngaphakathi kwephondo, ngaloo ndlela yenze uphawu oluthile lwemitha olunokuhlangabezana neemfuno ze-polarization ejikelezayo.

Isixhumi esinqamlezileyo: Isixhumi esinqamlezileyo esikhethekileyo sidla ngokufakelwa ngaphakathi kwi-antenna ye-horn ukuze sidibanise izinto zombane ezithe tye nezithe nkqo kunye nomahluko wesigaba sama-90 degrees. Olu yilo luvumela i-antenna ukuba ivelise ipateni yemitha ejikelezileyo ejikelezayo.

Imisebe yeendlela ezininzi: Uyilo lwe-antenna ye-polarized horn eyi-circularly polarized luyenza ikwazi ukukhupha iindlela ezininzi ze-electromagnetic fields ngaxeshanye, kuquka ne-circularly polarized signals ezijikeleza kwiindlela ezahlukeneyo ze-polarization.

Okwangoku, ii-antenna ze-horn ezijikelezileyo ezi-polarized zisetyenziswa kakhulu kwiimeko ezahlukeneyo zesicelo, kubandakanya unxibelelwano lwesathelayithi, unxibelelwano oluphathwayo, umlinganiselo werediyo, i-aerospace, i-radar, kunye nee-drones.
