QHAGAMSHELANA NGOKU

I-eriyali ecwangcisiweyo yi-eriyali esetyenziselwa ukusasaza nokufumana imiqondiso yombane ejikelezayo ejikelezayo esithubeni, enezi mpawu zilandelayo kunye nokusetyenziswa.

Uphawu

1. Imo ye-polarization: I-eriyali ye-Planar spiral ine-polarization mode yesandla sasekhohlo okanye imo ye-polarization yasekunene.
2. I-impedance ehambelanayo: I-eriyali ye-Planar spiral ine-impedance elungileyo ehambelana nokusebenza.
3. Umkhombandlela wokusasazeka kwemitha: I-antenna inokusebenza kakuhle kwicala lemitha yemitha, kunye necala lemitha yemitha ephezulu likwicala eliqhelekileyo kumacala omabini enqwelomoya kunye namaza asasaza kwipolarized circularly.
4. Iimpawu ezingaxhomekekanga kwi-frequency: ezifana ne-equiangular spiral antennas, imilo yazo imiselwa nge-engile kwaye ayibandakanyi ubude bomgca, iimpawu zazo azichatshazelwa lutshintsho lwamaza, kwaye zinebhendi yefrikhwensi ebanzi ngokugqithisileyo.

Isicelo

1. Ukuqhelaniswa nokuqhelaniswa: Ngenxa yemowudi yesandla sasekhohlo okanye sasekunene kunye nokusebenza kakuhle kolwalathiso lwemitha, i-eriyali yophondo inokufumana ngokuchanekileyo imiqondiso ye-electromagnetic kwiindlela ezithile kunye ne-polarizations yokwamkelwa kwakhona kokujoliswa ekujoliswe kuko kunye nemithombo yomqondiso.
2. Unxibelelwano ngesathelayithi: I-eriyali ye-RF inokusetyenziswa njengomthombo wesondlo kwiisathelayithi ezikhanyayo, ukondla ngokufanelekileyo imiqondiso yesathelayithi ebuthathaka efunyenweyo kwisixhobo sokwamkela.
3. Eminye imimandla: I-antenna ye-Microwave horn nayo inezicelo kwiinkqubo zonxibelelwano lwe-ultra-wideband, i-radar yomkhosi, i-biotechnology, kunye nezinye iinkalo, ezifana nokuphepha ukuphazamiseka phakathi konxibelelwano lwe-ultra-wideband kunye ne-narrowband yonxibelelwano.

QualwaveIbonelela ngee-eriyali zeplani ezijikelezayo zigubungela uluhlu lwamaza ukuya kuthi ga kwi-40GHz. Sinikezela ngee-eriyali zophondo oluqhelekileyo lwenzuzo ye-5dB, kunye nee-eriyali ezilungelelanisiweyo eziphindwe kabini zophondo ngokweemfuno zabathengi.
