Chekutanga, musimboti we antenna:
1.1 Tsanangudzo yeantenna:
Mudziyo unogona kuburitsa mafungu emagetsi anotungamira kune rimwe divi munzvimbo kana kuti unogona kugamuchira mafungu emagetsi anotungamira kubva kune rimwe divi munzvimbo.
1.2 Mabasa eAntena:
Ø Kushandurwa kwesimba - kushandurwa kwemafungu anotungamirwa uye mafungu enzvimbo yakasununguka; Mwaranzi inotungamira (kugamuchira) - ine gwara rakati.
1.3 Antena mwaranzi musimboti:
1.4 Magadzirirwo eAntena
Paramita yemwaranzi
Ø Upamhi hwesimbi yesimba hafu, chiyero chekumberi nekumashure;
Ø nzira yekuparadzanisa polarization, kusarurana kwe cross polarization;
Ø Chinhu chinotungamira, kuwedzera kweantenna;
Ø Chidimbu chikuru, chidimbu chechipiri, kudzvinyirirwa kwedivi, zero kuzadza, kudzika kwedanda…
Paramita yedunhu
Chiyero cheVSWR chevoltage standing wave, reflection coefficient Γ, return loss RL;
Ø Impedance yekupinda Zin, kurasikirwa kwekutapurirana TL;
Ø kuzviparadzanisa Iso;
Ø Kupindirana kwepakati kwepakati kwechikamu chechitatu chePIM3…
Kaneti yedivi reAntena
Upamhi hwedanda rakatwasuka
Chiyero chemberi neshure: Chinotsanangura chiyero chesimba rinopfuudzwa mberi neantenna uye simba rinopfuudzwa kumashure mukati me±30°.
Hukama huripo pakati pekuwedzera nehukuru hweantenna uye beamwidth
Kuderedza "tai", chiratidzo chinowedzera kusimba, kuwedzera kwekuwedzera, saizi yeantenna yakakura, uye hupamhi hwebeamwidth hunowedzera kutetepa;
Zvimwe zvinhu zvakakosha zvekuwedzera antenna:
Antena iyi mudziyo usingashande uye haigone kugadzira simba. Kuwana maAntena kunongoreva kugona kusanganisa simba zvinobudirira kuti ribudise kana kugamuchira mafungu emagetsi nenzira yakatarwa.
Ø Kuwana kweantenna kunogadzirwa ne superposition yema vibrator. Kuwana kwakakwira, ndiko kureba kwe antenna. Wedzera kuwana ne 3dB uye wedzera vhoriyamu kaviri.
Kana antenna ikawedzera, kutungamira kuri nani, simba rakawanda rakawanda, uye chikamu chayo chidiki.
1.5 Maparamita eMwaranzi
Polarization: zvinoreva nzira kana shanduko yemagetsi emagetsi muchadenga.
1.6 Maparamita eDunhu
Kurasikirwa kwekudzoka
Chechipiri, zvigadzirwa zve antenna
2.1 Nzira yeKutumidza Mazita eAntena:
Mapoka eantena: ODP (antenna yeplate yekunze), OOA (antenna yekunze yemhoni), IXD (antenna yedenga remukati), OCS (antenna yekunze yemativi maviri), OCA (antenna yekunze yeboka), OYI (antenna yekunze yeYagi), ORA (antenna yekukanda pamusoro pekunze), IWH (antenna yakaiswa pamadziro emukati) nezvimwewo.
Hafu yesimba Angle: 032,065,090,105,360 (antenna yechiteshi chepasi) 020,030,040,050,060,075,090,120,160,360 (antenna inodzokorora)
Maitiro ekupopotera: R(popotera kaviri), V(popotera imwe chete)
Kuwana: Kukosha kwakanyanya i21dbi zvichibva pamutengo chaiwo
Mhando dzemajoini: D (musoro weDin), N (musoro werudzi rweN), S (musoro weSMA), T (musoro weTNC) nezvimwewo
Bhendi remafrequency:
Kodhi yekutsanangura: Mabhii echiRoma anoratidza kugadzirwa kwechigadzirwa. Mabhii nenhamba zvinotevera zvinoratidza kudonha kweAngle, chimiro, nerumwe ruzivo. Rudzi rweF; V regulation yemagetsi; RV remote electric modulation
2.2 Antena yeBase Station
Kanema yeOmnidirectional Dual-Frequency
Kaneti yeMakanzuru Atatu
Antena yedenga
Antena Yakaiswa pamadziro
Antena yeYagi
Antena yeGrid
Broadband Omnidirectional Antena Log-Periodic Antena Plate Antena
3.1 Mugovanisi weSimba
Chinoparadzanisa simba mudziyo unoparadzanisa simba rechiratidzo chimwe chete chinobuda kuita ma outputs maviri kana kupfuura. Chaizvoizvo i-impedance converter.
Ø Chinopatsanura simba chinogona kudzoserwa shure kuti chitsive chinosanganisa?
Kana ikashandiswa se synthesizer, haingodi chete kupatsanurwa kwakanyanya, chiyero chidiki chekumira, asiwo inotarisa pane zvinodiwa kuti ikwanise kutsungirira simba rakawanda. Tichifunga kuti maburi ekubuda e cavity power splitter anoshandiswa kazhinji haaenderane, mafungu makuru akamira; Nekuda kwesimba diki re microstrip power splitter, hatikurudzire kushandisa power splitter kutsiva combiner.
Mugovanisi weSimba reMugovanisi
Chechina, sumo yekubatanidza
4.1 Muchina wekubatanidza
Ø Coupler rudzi rwechikamu chinogovera simba rechiratidzo chekupinda kuburikidza nemagetsi uye magnetic field coupling kuti ive chikamu che coupling end output, uye zvimwe zvese zve output end output kuti zvipedzise kugoverwa kwesimba.
Ø Kugoverwa kwesimba kwemuchina wekubatanidza hakugovaniswe zvakaenzana. Inozivikanwawo semuchina wekuenzanisa simba.
Chinobatanidza chinonongedzera
Makomputa ekubatanidza anoshandiswa nenzira yakatarwa anowanzo shandiswa negwara rekufamba kwezviratidzo zve microwave pakutora sampuli, chinangwa chikuru ndechekuparadzanisa nekuparadzanisa chiratidzo, kana kusanganisa zviratidzo zvakasiyana, kana pasina mutoro wemukati, makomputa ekubatanidza nzira anowanzo kuve network ine madoko mana.
Muchina wekubatanidza mugomba
Zvimiro: Kutakura simba rakawanda, kurasikirwa kwakaderera.
Chikonzero:
1. Mugodhi wakazara nemhepo, uye panguva yekutumira, kupararira kwenhau kunokonzerwa nemhepo kunenge kwakaderera zvikuru.
2. Bhandi rewaya rakabatana rinowanzogadzirwa neconductor ine conductivity yakanaka yemagetsi (yakadai sekuputira sirivha pamusoro pemhangura), uye kurasikirwa kweconductor hakunyanyi kukosha.
3. Huremu hwakakura hwegomba, kupisa kunokurumidza kupera. Kutsungirira simba rakawanda.
Chinodzivirira
Ø Chinobatidza chinhu chine maburi maviri anopindirana
Zvinonyanya kushandiswa zvinoderedza kupisa ndezvinoderedza kupinza kwemvura.
Chinovhara masimbi chinowanzo shandiswa muinjiniya, chinosanganisira network ye "π" kana "T".
Zvishandiso zvinodzivirira tambo dzeCoaxial zvinowanzova nemhando mbiri dzezvishandiso zvinodzivirira tambo dzakagadzika uye dzinochinja-chinja.
Ø MaAttenuator anonyanya kushandiswa kudzora simba rekutumira kwezviratidzo zve microwave musystem yekuona uye kushandisa simba rakawandisa, nokudaro achiwedzera huwandu hwesimba rekuyera zviratidzo, zvakaita se power metres, spectrum analyzers, amplifiers, receivers, nezvimwewo.

衰减器
Ø衰减器是二端口互易元件
Ø衰减器最常用的是吸收式衰减器.
Ø工程中通常使用的是同轴型衰减器，由“π”型或“T”型衰减网络组成.
Ø同轴衰减器通常有固定及可变衰减两种.
Ø扩展信号测量的动态范围，诸如功率计，频谱分析仪，放大器，接收器等.
