- Inyungu ya antene niyihe nyungu?
Antennainyungu bivuga ikigereranyo cyubucucike bwimbaraga za signal zakozwe na antenne nyirizina hamwe nigice cyiza cyo kumurika ahantu hamwe mumwanya muburyo bwo kwinjiza imbaraga zingana. Irasobanura muburyo urwego antenne yerekana imbaraga zinjiza muburyo bwibanze. Inyungu biragaragara ko ifitanye isano ya hafi na antenne. Gufunga umurongo nyamukuru wubushushanyo kandi ntoya kuruhande, niko inyungu nyinshi. Inyungu ya Antenna ikoreshwa mugupima ubushobozi bwa antenne yo kohereza no kwakira ibimenyetso muburyo bwihariye. Nibimwe mubintu byingenzi byingenzi byo guhitamo sitasiyo ya sitasiyo.
Muri rusange, iterambere ryunguka ahanini rishingiye ku kugabanya ubugari bwumurambararo wimirasire ihagaritse mugihe gikomeza imikorere yimirasire yibintu byose mumurongo utambitse. Kwiyongera kwa Antenna ni ingenzi cyane kumikorere yimikorere ya sisitemu yitumanaho rya terefone igendanwa kuko igena urwego rwibimenyetso kuruhande rwakagari. Kongera inyungu birashobora kongera ubwishingizi bwurusobe muburyo runaka, cyangwa kongera inyungu murwego runaka. Sisitemu iyo ari yo yose ni inzira ebyiri. Kongera inyungu za antenne birashobora icyarimwe kugabanya inyungu yingengo yimari ya sisitemu yuburyo bubiri. Mubyongeyeho, ibipimo byerekana inyungu za antenne ni dBd na dBi. dBi ninyungu ugereranije na antenne yinkomoko, kandi imirasire mubyerekezo byose irasa; dBd ijyanye ninyungu ya antenna ya simmetrike ya antenna dBi = dBd + 2.15. Mubihe bimwe, uko inyungu nyinshi, niko intera ya radiyo ishobora gukwirakwiza.
Antenna yunguka igishushanyo
Mugihe uhitamo antenne yunguka, bigomba kugenwa ukurikije ibikenewe bya porogaramu yihariye.
- Itumanaho rigufi: Niba intera y'itumanaho ari ngufi kandi nta mbogamizi nyinshi, inyungu ya antenne ntishobora gukenerwa. Muri iki kibazo, inyungu yo hasi (nka0-10dB) birashobora gutoranywa.
RM-BDHA0308-8 （0.3-0.8GHz ， 8 Ubwoko.dBi）
Itumanaho rito hagati: Kugirango itumanaho rito, inyungu ya antenne iringaniye irashobora gusabwa kwishyura indishyi zerekana Q zatewe nintera yoherejwe, mugihe hanazirikanwa inzitizi zibidukikije. Muri iki gihe, inyungu ya antenne irashobora gushirwa hagati10 na 20 dB.
RM-SGHA28-15 (26.5-40 GHz, 15 Ubwoko. DBi)
Itumanaho rirerire: Kubireba itumanaho rigomba gukora urugendo rurerure cyangwa rufite inzitizi nyinshi, inyungu nyinshi za antenne zirashobora gusabwa gutanga imbaraga zihagije zo gutsinda ibibazo byintera yoherejwe nimbogamizi. Muri iki gihe, inyungu ya antenne irashobora gushirwa hagati 20 na 30 dB.
RM-SGHA2.2-25 (325-500GHz ， 25 Ubwoko. DBi）
Ibidukikije-urusaku rwinshi: Niba hari byinshi bivangavanze n urusaku mubidukikije byitumanaho, antene yunguka cyane irashobora gufasha kunoza igipimo cyerekana-urusaku bityo bikazamura ireme ryitumanaho.
Twabibutsa ko kwiyongera kwa antenne bishobora guherekezwa nigitambo mubindi bice, nko kuyobora antenne, ubwishingizi, ikiguzi, nibindi. Kubwibyo rero, mugihe uhisemo inyungu za antenne, ni ngombwa gusuzuma ibintu bitandukanye no gufata ibyemezo bikwiye ukurikije umwihariko. uko ibintu bimeze. Imyitozo myiza nugukora ibizamini byo murwego cyangwa gukoresha software yigana kugirango isuzume imikorere munsi yinyungu zinyuranye kugirango ubone inyungu zisanzwe zishyirwaho.
Kugira ngo umenye byinshi kuri antene, nyamuneka sura:
