Kuyini ukuqondiswa kwe-antenna
Ukuqondisa kuyipharamitha ye-antenna eyisisekelo. Lesi yisilinganiso sokuthi iphethini yemisebe ye-antenna eqondisayo injani. I-antenna ekhipha ngokulinganayo kuzo zonke izinkomba izoba nokuqondisa okulingana no-1. (Lokhu kulingana nama-decibel ayi-zero -0 dB). Umsebenzi we...Funda kabanzi -
Funda ngama-antenna ahleliwe
I-antenna eqondile uhlobo lwe-antenna olusetshenziswa kakhulu ezinhlelweni zokuxhumana. Inesakhiwo esilula futhi kulula ukusenza. Ingahlelwa endaweni eyisicaba, njengepuleti lensimbi, ibhodi lesifunda eliphrintiwe, njll. Ama-antenna eqondile enziwe ngensimbi futhi ngokuvamile...Funda kabanzi -
Ukusebenza kahle kwe-antenna kanye nokuzuza kwe-antenna
Ukusebenza kahle kwe-antenna kuhlobene namandla anikezwa i-antenna kanye namandla akhishwa yi-antenna. I-antenna esebenza kahle kakhulu izokhipha iningi lamandla alethwa ku-antenna. I-antenna engasebenzi kahle imunca iningi lamandla alahlekile ngaphakathi kwe-antenna...Funda kabanzi -
Ukuhlaziywa kwesakhiwo, isimiso sokusebenza kanye nezimo zokusetshenziswa kwama-antenna e-microstrip
I-antenna ye-Microstrip iyi-antenna encane evamile, equkethe i-patch yensimbi, i-substrate kanye ne-ground plane. Isakhiwo sayo simi kanje: Ama-patch ensimbi: Ama-patch ensimbi avame ukwenziwa ngezinto eziqhuba ugesi, njengethusi, i-aluminium,...Funda kabanzi -
Ububanzi be-antenna
I-bandwidth ingenye ipharamitha ye-antenna eyisisekelo. I-bandwidth ichaza ububanzi bemvamisa i-antenna engakhipha noma yamukele amandla ngendlela efanele. Ngokuvamile, i-bandwidth edingekayo ingenye yamapharamitha asetshenziswa ukukhetha uhlobo lwe-antenna. Isibonelo, kune-m...Funda kabanzi -
Ukubaluleka kwama-antenna emkhakheni wezempi
Emkhakheni wezempi, ama-antenna awubuchwepheshe obubaluleke kakhulu. Inhloso ye-antenna ukwamukela nokudlulisa izimpawu zemvamisa yomsakazo ukuze kuvunyelwe ukuxhumana okungenantambo namanye amadivayisi. Ezicini zokuzivikela nezempi, ama-antenna adlala indima ebalulekile njengoba esetshenziswa...Funda kabanzi -
Imvamisa ye-antenna
I-antenna ekwazi ukudlulisa noma ukwamukela amaza kagesi (EM). Izibonelo zala maza kagesi zihlanganisa ukukhanya okuvela elangeni, kanye namaza atholwa yiselula yakho. Amehlo akho athola ama-antenna athola amaza kagesi kagesi endaweni ethile...Funda kabanzi -
Idizayini yesiguquli semvamisa ye-RF-Isiguquli se-RF Up, Isiguquli se-RF Down
