Kutanga, iyo antenna musimboti:
1.1 Tsanangudzo yeantenna:
Chishandiso chinogona kunyatso kupenya mafungu emagetsi kune imwe nzira munzvimbo kana kuti inogona kunyatso kugashira masaisai emagetsi kubva kune imwe nzira munzvimbo.
1.2 Antenna inoshanda:
Ø Shanduko yesimba - shanduko yeinotungamirwa wave uye yemahara nzvimbo wave;Directional mwaranzi (reception)- ine imwe nzira yakananga.
1.3 Antenna radiation musimboti:
1.4 Antenna Parameters

Ø Half simba danda upamhi, kumberi kune kumashure chiyero;
Ø polarization mode, kuyambuka polarization kusarura;
Ø Directivity factor, antenna kuwana;
Ø Main lobe, yechipiri lobe, sidelobe kudzvinyirira, zero kuzadza, danda kudzika ...
Circuit parameter
Voltage yakamira wave ratio VSWR, reflection coefficient Γ, kudzoka kurasikirwa RL;
Ø Input impedance Zin, kutapurirana kurasikirwa TL;
Ø kuparadzaniswa Iso;
Ø Passive wechitatu odha Intermodulation PIM3…
Antenna parutivi
Horizontal Beam Width
Pamberi neshure reshiyo: Inotsanangura reshiyo yesimba remberi rakavhenekerwa kune antenna uye yekumashure inopenya simba mukati me ± 30 °.
Hukama huri pakati pekuwana uye saizi yeantenna uye beamidth
Kupfapfaidza "tairi", iyo yakanyanya kuisa chiratidzo, iyo inowedzera kuwedzera, iyo yakakura saizi yeantenna, uye yakamanikana iyo beamwidth;
Mamwe mashoma mapoinzi ekuwana antenna:
Iyo antenna chigadziriso uye haigone kuburitsa simba.Antenna kuwana ingori kugona kunyatso kumisa simba kupenya kana kugashira mafungu emagetsi mune imwe nzira.
Ø Kuwana kweantenna kunogadzirwa nepamusoro peiyo vibrators.Iyo yakakwirira kuwana, iyo yakareba iyo antenna kureba.Wedzera kuwana ne 3dB uye kaviri vhoriyamu.
Iyo yakakwira iyo antenna kuwana, zviri nani kurongeka, iyo yakawedzera kuisa simba, uye kutetepa lobe.
1.5 Radiation Parameters
Polarization: inoreva trajectory kana shanduko yemagetsi munda vector munzvimbo.
1.6 Circuit Parameters

3.1 Power Divider
Simba divider mudziyo unopatsanura simba reimwe inobuda chiratidzo kuita zviviri kana kupfuura zvinobuda.Izvo chaizvo inoshandura impedance.
Ø Ko iyo inoparadzanisa simba inogona kudzoserwa kutsiva musanganisi?
Kana ichishandiswa se synthesizer, haingodi chete yakakwirira yekuzviparadzanisa nevamwe, yakaderera yakamira wave ratio, asi zvakare inotarisisa pane chinodiwa kumira nesimba repamusoro.Tichifunga kuti zvinobuda zviteshi zveanowanzo shandiswa mhango simba splitter hazvienderane, hombe yakamira wave;Nekuda kwekushomeka kwesimba rekudzivirira kweiyo microstrip simba splitter, isu hatikurudzire kushandisa simba rekuparadzanisa kutsiva musanganisi.
Cavity Power Divider
Chechina, chisumo che coupler
4.1 Coupler
Ø Coupler imhando yechikamu chinogovera simba reiyo yekuisa chiratidzo kuburikidza nemagetsi emagetsi uye magineti yekubatanidza magineti kuti ive chikamu chekubatanidza kupera kunobuda, uye yakasara yekubuda kunopera kupedzisa kugovera kwemagetsi.
Ø Kugovewa kwesimba kwevaviri hakuna kugovaniswa zvakaenzana.Iyo inozivikanwawo sesimba sampler.
Directional coupler
Directional couplers inowanzoshandiswa neyakatsanangurwa kuyerera kwechiratidzo che microwave masaini esampling, chinangwa chikuru ndechekuparadzanisa uye kupatsanura chiratidzo, kana kusanganisa kusanganisa masaini akasiyana, mukushaikwa kwemutoro wemukati, anotungamira mabhatani anowanzo ari mana-chiteshi network.
Cavity coupler
Zvimiro: Kutakura simba guru, kuderera kwekurasikirwa kwekuita.
Chikonzero:
1. Iyo mhango yakazadzwa nemhepo, uye muhutano hwekutumira, kusvibiswa kwevhidhiyo kunokonzerwa nemhepo yemhepo yakaderera zvikuru.
2. Bhandi rewaya rakasanganiswa rinowanzoitwa nekondukita ane yakanaka magetsi conductivity (senge sirivheri plating pamusoro pemhangura pamusoro), uye kurasikirwa conductor kunonyanya kusakosha.
3. Hombe mhango volume, kukurumidza kupisa kupera.Kumirisana nesimba guru.
Attenuator
Ø Iyo attenuator chinhu chechipiri-chiteshi chekudzoka
Iwo anonyanya kushandiswa attenuators ndeaya absorption attenuators.
Coaxial attenuator inowanzo shandiswa muinjiniya, inosanganisira "π" kana "T" attenuation network.
Coaxial attenuators kazhinji ane marudzi maviri eakagadziriswa uye akasiyana attenuators.
Ø Attenuators anonyanya kushandiswa kudzora simba rekutapurirana rema microwave masiginecha muhurongwa hwekuona uye kushandisa simba rakawandisa, nekudaro achiwedzera huwandu hwesimba hwekuyerwa kwechiratidzo, senge magetsi metres, spectrum analyzers, amplifiers, vanogamuchira, nezvimwe.
