Kutanga, Iyo Antenna Pfungwa:
1.1 Tsanangudzo yeAntenna:
Chishandiso chinogona kunyatso kupenya electromagnic mafungu kune imwe nzira iri munzvimbo kana inogona kuwana zvinobudirira magetsi emagetsi kubva kune yakatarwa nzira munzvimbo yakatarwa munzvimbo.
1.2 Antenna Mabasa:
Ø Energy kushandurwa - kutendeuka kwekutungamirirwa wave uye nzvimbo yemahara mafungu; Kutungamira radiation (kugamuchira) - ine kumwe kukaniswa.
1.3 Antenna Radiation Nheyo:
1.4 antenna parameter
Radiation paramende
Ø Hafu Simba Beam Yepamhi yakafara, kumberi kudzoka ratio;
Ø Mudziviriro modhi, kuyambuka polisization kusarura;
Ø Kukwirisa kutaura, uye antenna kuwana;
Ø Main lobel, Sekondari Lobe, Sidelobe kudzvinyirira, zero kuzadza, beam downtilt ...
Circer Paramende
Voltage yakamira wave wave ratio vswr, kuratidzwa coefficien γ, kudzoka kurasikirwa rl;
Ø Input Imcedance zin, kutamisa kurasikirwa TL;
Ø kuparadzaniswa imo;
Ø Passive yechitatu kuraira kupindirana pim3 ...
Antenna Sidelobe
Yakatwasuka beam yakafara
Pamberi pekudzokera kumashure Ratio: Inotsanangura huwandu hwerudzi rwemberi rakatsemuka simba kune antenna uye iyo yakadzorerwa yakadururwa simba mukati me10 °.
Hukama pakati pekuwana uye antenna size uye beamwidth
Flatting the "Tire" yakanyanya kumira seyakaenzana, iyo yakakwira mibairo, yakakura size, saizi yakadzikama, uye inoyera ngowani;
Pfungwa shoma dzinokosha dzeAntenna kuwana:
Iyo Antenna mudziyo unopfuura uye haugone kuburitsa simba. Antenna kuwana ingori kugona kwekutarisisa simba rinobudirira kupenya kana kugashira mafungu electromagnet.
Ø Kuwana kweAntenna kunogadzirwa nehuremu hwevanhu vibrators. Iyo yakakwira kuwana, yakareba iyo antenna kureba. Wedzera kuwana iyo 3db uye kaviri vhoriyamu.
Iyo yepamusoro iyo antenna kuwana, zviri nani kuwirirana, iyo yakanyanya kusimbisa simba, uye inoyevedza dombo.
1.5 radiation parameter
Polarization: zvinoreva kune trajectory kana shanduko yeiyo yemagetsi munda vector munzvimbo.

3.1 Simba Divider
Iyo Simba Divider chishandiso chinokamura simba reimwe chiratidzo chiratidzo kuita maviri kana anopfuura ekubuda. Izvo zvinonyadziswa zvinoshandurwa.
Ø Inogona kuganhurana simba rinodzoserwa kutsiva here?
Kana ichishandiswa seyakagadziriswa, haina kungoda kuzviparadzanisa zvakanyanya, yakamira zera ratio, asiwo inotarisa pane chinodiwa kuti irambe yakasimba simba. Kufunga kuti iyo inobuda muchiteshi cheiyo inowanzoshandiswa masimba eCavity Splitter haafanane, akareba akamira masaya; Nekuda kwekudzikisira kwemagetsi simba kweiyo microsttrip Simba Splitter, isu hatikurudzire kushandisa simba kupururudza kutsiva iyo inosanganisa.
Cavity Simba Divider
Ina, iyo coupler sumo
4.1 coupler
Ø Coupler rudzi rwechikamu chinogovera simba rekuisa siginecha yemusangano nemagirazi uye magineti muchikamu chekupedza chidimbu chekupedzisira, uye zvimwe zvinobuda mugumo kupedzisa kugovera kwesimba.
Ø Kugoverwa kwesimba kwemupiyaniso hakuna kupatsanurwa zvakaenzana. Inozivikanwa seSimba Sampuli.
Kutungamira kaviri
Mabhonari anotungamira anowanzo shandiswa neyekutaurwa nzira yekuyerera yeMicrowave Signals, chinangwa chikuru ndechekusanganisa chiratidzo, mukushaikwa kwemutoro wemukati, kutungamira kwemativi emukati kazhinji kune ina-port network.
Cavity Coupler
Zvimiro: Kutakura simba rakakwira, kurasikirwa kwakaderera kwekuita.
Chikonzero:
1. Iyo yemukati izere nemhepo, uye nenzira yekufambisa, iyo midhiya yekusagadzikana inokonzerwa neyemhepo yakadzika zvakanyanya.
2. Iyo yarayori wire bhandi inowanzogadzirwa nemucheto neakanaka magetsi maitiro (senge sirivheri puru pane yemhangura), uye kurasikirwa kweConders hakuenderani.
3. Huru yeCavity vhoriyamu, inokurumidza kupisa kusarongeka. Ingarasa simba repamusoro.
Attenuator
Ø The Attenuator ndeye maviri-port recrocal element
Inonyanya kushandiswa maAgenthuators ari vateveri.
A colaaator attenuator inowanzoshandiswa muinjiniya, inosanganisira ye "π" kana "t" dentenuation network.
Colaxal Atenuators anowanzove nemhando mbiri dzakarongedzwa uye dzakasarudzika vatenzi.
Ø Vatenderi vanonyanya kushandiswa kudzora simba rekutapurika reMicrowave System uye vanowedzera simba rekuyera, senge metres metrums, vanoongorora special, amplifiers, vanogamuchira, nezvimwe.
