Izisekelo ze-Antenna: Ama-Antenna Akhanya Kanjani?
Uma kukhulunywa ngama-antenna, umbuzo abantu abakhathazeke kakhulu ngawo uthi "Kufinyelelwa kanjani ngempela imisebe?" Insimu kagesi ekhiqizwa ngumthombo wesignali isakazeka kanjani ngomugqa wokudlulisela nangaphakathi kwe-antenna, futhi ekugcineni "ihlukane" ...Funda kabanzi -
Isingeniso kanye nokuHlela i-Antena
1. Isingeniso kuma-Antenna I-antenna iyisakhiwo sokushintsha phakathi kwesikhala esikhululekile nomugqa wokudlulisela, njengoba kuboniswe kuMfanekiso 1. Umugqa wokudlulisela ungaba ngesimo somugqa we-coaxial noma ithubhu elingenalutho (i-waveguide), elisetshenziselwa ukudlulisa amandla kagesi...Funda kabanzi -
Ukusebenza Kahle Kwe-Antena Nokuzuza: Amafomula, Ukulahlekelwa Nokulinganisa
Ukusebenza kahle kwe-antenna kuchaza ukuthi amandla e-RF amukelwa kahle aguqulwa kanjani abe amandla akhishwa imisebe. Kuyipharamitha ebalulekile ye-antenna ngoba ukulahlekelwa ngumqhubi, ukulahlekelwa yi-dielectric kanye nokungafani kwe-impedance kunganciphisa imisebe esebenzisekayo ngisho noma i-antenna inephethini efanelekile. Isisekelo...Funda kabanzi -
Kuyini i-Beamforming?
Emkhakheni wama-antenna e-array, i-beamforming, eyaziwa nangokuthi ukuhlunga kwesikhala, iyindlela yokucubungula isignali esetshenziselwa ukudlulisa nokwamukela amaza omsakazo angenantambo noma amaza omsindo ngendlela eqondisa ngqo. I-Beamforming iwukuxhumana...Funda kabanzi -
Incazelo eningiliziwe yesibonisi sekona se-trihedral
Uhlobo lwe-radar target noma i-reflector ye-passive esetshenziswa ezinhlelweni eziningi ezifana nezinhlelo ze-radar, ukulinganisa, kanye nokuxhumana ibizwa ngokuthi i-reflector engunxantathu. Amandla okubonakalisa amaza kagesi (njengamaza omsakazo noma izimpawu ze-radar) abuyele ngqo emthonjeni,...Funda kabanzi -
Ama-antenna empondo kanye nama-antenna ahlukaniswe kabili: izinhlelo zokusebenza nezindawo zokusebenzisa
I-antenna yempondo kanye ne-antenna ephindwe kabili kuyizinhlobo ezimbili zama-antenna asetshenziswa emikhakheni eyahlukene ngenxa yezici nemisebenzi yawo eyingqayizivele. Kulesi sihloko, sizohlola izici zama-antenna empondo kanye ne-antenna ephindwe kabili...Funda kabanzi -
Ukusetshenziswa kobuchwepheshe be-RFMISO vacuum brazing
Indlela yokubilisa esithandweni somoya iwuhlobo olusha lobuchwepheshe bokubilisa olwenziwa ngaphansi kwezimo zomoya ngaphandle kokwengeza ukugeleza. Njengoba inqubo yokubilisa yenziwa endaweni yomoya, imiphumela elimazayo yomoya emsebenzini ingasuswa ngempumelelo...Funda kabanzi -
Isingeniso sohlelo lokusebenza lwe-Waveguide kuya ku-coaxial converter
Emkhakheni wokudluliselwa kwesignali yerediyo kanye ne-microwave, ngaphezu kokudluliselwa kwesignali engenantambo engadingi imigqa yokudlulisela, izimo eziningi zisadinga ukusetshenziswa kwemigqa yokudlulisela...Funda kabanzi -
I-RHCP vs LHCP: Indlela Yokubona Ukuhlukaniswa Okuyindilinga
I-polarization eyindilinga yesandla sokunene (RHCP) kanye ne-polarization eyindilinga yesandla sokunene (LHCP) zichaza indlela i-vector yensimu kagesi ejikeleza ngayo njengoba igagasi le-electromagnetic lisakazeka. Ukuhlonza okulungile kubalulekile ekuxhumaneni kwesathelayithi, i-radar, ukulinganiswa kwe-antenna kanye ...Funda kabanzi -
Isebenza kanjani i-antenna ye-microstrip? Uyini umehluko phakathi kwe-antenna ye-microstrip ne-antenna ye-patch?
I-antenna ye-Microstrip uhlobo olusha lwe-antenna ye-microwave esebenzisa imichilo yokuhambisa ephrintiwe ku-substrate ye-dielectric njengeyunithi yokukhipha imisebe ye-antenna. Ama-antenna e-Microstrip asetshenziswe kabanzi ezinhlelweni zokuxhumana zesimanje ngenxa yobukhulu bawo obuncane, isisindo esincane, kanye nephrofayili ephansi...Funda kabanzi -
Incazelo kanye nokuhlaziywa kwezigaba okuvamile kwama-antenna e-RFID
Phakathi kobuchwepheshe bokuxhumana obungenantambo, ubuhlobo kuphela phakathi kwedivayisi ye-transceiver engenantambo kanye ne-antenna yohlelo lwe-RFID obukhetheke kakhulu. Emndenini we-RFID, ama-antenna kanye ne-RFID kubaluleke ngokulinganayo ...Funda kabanzi -
Iyini imvamisa yomsakazo?
Ubuchwepheshe be-Radio Frequency (RF) buwubuchwepheshe bokuxhumana obungenantambo, obusetshenziswa kakhulu emsakazweni, kwezokuxhumana, kwi-radar, kwi-remote control, kumanethiwekhi ezinzwa ezingenantambo nakwezinye izinkambu. Umgomo wobuchwepheshe be-radio frequency obungenantambo usekelwe ekusakazweni nasekuguqulweni...Funda kabanzi
