Dunida anteenada, waxaa jira sharci noocaas ah. Marka si toosan loo sameeyoanteeno kala qaybsangudbiya, waxaa heli kara oo keliya anteeno toosan oo kala qaybsan; marka anteeno toosan oo kala qaybsan ay gudbiso, waxaa heli kara oo keliya anteeno si toosan u kala qaybsan; marka gacanta midigAnteeno wareegsan oo kala qaybsanGudbinta, waxaa lagu heli karaa oo keliya anteeno wareegsan oo gacanta midig ah; marka anteeno wareegsan oo bidix ah ay gudbiso, waxaa lagu heli karaa oo keliya anteeno wareegsan oo gacanta midig ah; Anteenada wareegsan ee kala qaybsan ayaa gudbisa waxaana lagu heli karaa oo keliya anteeno wareegsan oo bidix ah.

RFMISOAlaabooyinka anteenada geeska ee wareegsan ee la kala fogeeyay
Anteenada toosan ee loo yaqaan 'voltage polarized anteenada' waxay tilmaamaysaa hirarka ay soo saarto anteenada, jihada kala-goysyaduna waa mid toosan.
Jihada kala-goynta ee hirarka waxay tilmaamaysaa jihada vector-ka goobta korantada.
Sidaa darteed, jihada kala-goynta ee hirarku waa mid toosan, taasoo la macno ah in jihada vector-ka goobta korontada uu yahay mid toosan.
Sidoo kale, anteeno si toosan u kala qaybsan macnaheedu waa in jihada hirarku ay tahay mid toosan, taasoo macnaheedu yahay in jihada goobta korantada ee hirarka ay soo saarto ay la siman tahay dhulka.
Kala-soocidda toosan iyo kala-soocidda toosan labaduba waa nooc ka mid ah kala-soocidda toosan.
Waxa loogu yeero kala-goynta toosan waxay tilmaamaysaa kala-goynta hirarka, taas oo ah, jihada goobaha korontada ee jihada go'an. La hagaajiyay macnaheedu waa inaysan isbeddeli doonin.
Anteenada wareegsan ee kala qaybsan waxay tilmaamaysaa kala qaybsanaanta hirarka, taas oo ah, jihada goobta korantada, taas oo ku wareegta xawaare isku mid ah oo xagal ah marka waqtigu isbeddelo.
Haddaba sidee loo go'aamiyaa kala-soocidda wareegyada ee bidix iyo midig?
Jawaabtu waxay ku jirtaa gacmahaaga.
Labada gacmoodba dibadda u soo saar, iyagoo suulkooda ku tilmaamaya jihada faafitaanka hirarka, ka dibna arag faraha gacanta ee qaloocan ee u wareegaya jihada kala-goynta.
Haddii gacanta midig ay isku mid tahay, waa kala qaybsanaanta gacanta midig; haddii gacanta bidix ay isku mid tahay, waa kala qaybsanaanta gacanta bidix.
Marka xigta, waxaan kuu sharixi doonaa qaacidooyin. Hadda bal qiyaas in ay jiraan laba hirar oo si toosan u kala qaybsan.
Hal jiho oo kala-goyn ah waa jihada x iyo baaxadda waa E1; hal jiho oo kala-goyn ah waa jihada y iyo baaxadda waa E2; labada hirarba waxay ku faafaan jihada z.
Marka la eego labada hirar, wadarta guud ee gaaska korontada waa:
Laga soo bilaabo qaacidada kor ku xusan, waxaa jira fursado badan:
(1) E1≠0, E2=0, markaa jihada kala-goynta ee hirarka diyaaradda waa dhidibka x-
(2) E1=0, E2≠0, markaa jihada kala-goynta ee hirarka diyaaradda waa dhidibka y
(3) Haddii E1 iyo E2 labaduba yihiin tirooyin dhab ah oo aan ahayn 0, markaa jihada kala-goynta ee hirarka diyaaradda waxay samaysaa xagasha soo socota iyadoo la adeegsanayo dhidibka x:
(4) Haddii uu jiro farqi gaar ah oo u dhexeeya E1 iyo E2, sida ka muuqata sawirka hoose, hirarka diyaaraduhu waxay noqon karaan hirar wareegsan oo gacanta midig ah ama hirar wareegsan oo gacanta bidix ah.
Si anteenooyinka toosan ee kala fog ay u helaan hirarka toosan ee kala fog, iyo anteenooyinka toosan ee kala fog si ay u helaan hirarka toosan ee kala fog, waxaad ku fahmi kartaa adigoo eegaya sawirka hoose.
Laakiin ka waran hirarka wareegsan ee kala qaybsan? Inta lagu jiro geeddi-socodka soo saarista kala qaybsanaan wareegsan, waxaa lagu helaa iyadoo la dul saarayo laba kala qaybsanaan toosan oo leh kala duwanaansho marxaladeed.
