Iindaba - Qonda imigaqo yoyilo kunye neempawu zokusebenza kwee-antenna ze-biconical

I-Antenna yeBiconical yi-antenna ekhethekileyo ebanzi enesakhiwo sayo esineekhowuni ezimbini zesinyithi ezilinganayo ezidityaniswe ezantsi kwaye ziqhagamshelwe kumthombo wesignali okanye umamkeli ngenethiwekhi yokutrim. Ii-antenna zeBiconical zisetyenziswa kakhulu kuvavanyo lokuhambelana kwe-electromagnetic (EMC), unxibelelwano olungenazingcingo kunye neenkqubo zeradar. Umgaqo osebenzayo we-antenna ye-biconical kukusebenzisa iimpawu zokubonakalisa kunye nemitha yamaza e-electromagnetic kwiikhondisi zesinyithi. Xa i-electromagnetic wave ingena kwi-antenna ye-biconical, iya kubonakaliswa amaxesha amaninzi kumphezulu wekhowuni, yenze isiphumo sokusasazwa kwe-multipath. Olu sasazo lwe-multipath lubangela ukuba i-antenna ivelise ipateni yemitha efanayo kwicala lemitha. Uphawu oluphambili lwee-antenna ze-biconical kukusebenza kwazo kwe-wide-band. Ingasebenza kuluhlu olukhulu lwe-frequency, idla ngokugubungela amakhulu ambalwa e-megahertz ukuya kwi-gigahertz ezininzi. Olu phawu lwenza ii-antenna ze-biconical zisetyenziswe kakhulu kuvavanyo lonxibelelwano olungenazingcingo lwe-wide-band kunye nokulinganisa, kunye novavanyo lwe-EMC lwezixhobo kwiindidi ezahlukeneyo ze-frequency. Ukongeza, ulwakhiwo lwe-antenna ye-biconical lulula kwaye kulula ukulwenza, ukuyifaka kunye nokusebenzisa. Nangona kunjalo, ii-antenna ze-biconical nazo zinemida ethile. Okokuqala, inzuzo ye-antenna iphantsi kakhulu ngenxa yokusebenza kwayo kwe-broadband. Okwesibini, ekubeni uyilo kunye nokuveliswa kwee-antenna kufuneka kuqwalaselwe uluhlu lwee-frequency kunye nezinye iimfuno, kunokubakho iimpawu ezahlukeneyo ze-antenna kwiibhendi ezithile ze-frequency. Ke ngoko, kuyimfuneko ukukhetha i-antenna efanelekileyo ye-biconical ngokweemfuno ezithile kwisicelo. Ngokubanzi, i-antenna ye-biconical yi-antenna ekhethekileyo enomsebenzi we-wide-band kwaye ifanelekile kunxibelelwano olungenazingcingo lwe-wide-band, uvavanyo lwe-EMC kunye nokulinganisa. Inezibonelelo zesakhiwo esilula, ukwenziwa kunye nokusetyenziswa okulula, kodwa kufuneka kuqwalaselwe ukukhethwa kwe-gain kunye neempawu ezahlukeneyo zebhendi ye-frequency.
