Muri sisitemu z'itumanaho rya mikoroonde, kwiyongera kwa antene ni ikimenyetso cy'ingenzi cyo gupima imikorere y'imirasire. Nk'umunyamwuga, nk'umuhanga mu by'ikoranabuhanga.umucuruzi wa antene za mikoroonde, tuzi neza akamaro ko kubara no gupima neza inyungu ya antene kugira ngo sisitemu irusheho kuba nziza. Iyi nkuru izafataAntene ya 40GHznaAntene ya Cassegrainnk'ingero zo kwerekana mu buryo burambuye uburyo bwo kubara n'ingingo zifatika zo gukurura antene.
1. Ishingiro ry'ibarura ry'inyigisho
Kongera antena (dBi) bigenwa n'ubuyobozi n'imikorere myiza:
Inyungu (dBi) = ubuyobozi × imikorere myiza
1. Kubara Ubuyobozi:
Antene zifite icyerekezo cyo hejuru (nk'antene za Cassegrain) ziboneka binyuze mu guhuza imiterere y'imirasire, zishobora gushyira ingufu mu rumuri ruto.
2. Ibipimo byo gukora neza:
Ibintu bikurikira by'igihombo bigomba kwitabwaho:
- Gutakaza uburyo bwo kohereza (nk'uko umutwaro w'umuyoboro utari uhuye neza)
- Igihombo cy'ibikoresho
- Ubuhanga bwo gutunganya ubuso
2. Uburyo bw'ubuhanga bwo gupima
1. Uburyo bwo gupima kugereranya:
Gereranya antene iri kugeragezwa (nk'antene ya 40GHz) na antene isanzwe ya gain horn.
2. Ikizamini cya kure:
Pima imiterere y'imirasire mu cyumba cy'umwijima cya mikoroonde, ari bwo buryo bw'igerageza bukoreshwa n'abatanga antena**.
3. Ikizamini cyo gusesengura umuyoboro w'itumanaho:
Suzuma igihombo cyo kugaruka kw'imirasire n'ubushobozi bw'imirasire binyuze mu isesengura rya S parameter.
Antena y'ihembe rya interineti(18-40GHz)
Antena yo gupima umuyoboro wa Waveguide(26.5-40GHz)
RFmisoIbicuruzwa bya Antena ya 40Ghz
3. Ikoranabuhanga ryo kugenzura imikorere y'ibishushanyo
Koresha porogaramu z’umwuga zo gupima amashanyarazi nka HFSS na CST:
- Kubara neza ubushobozi bw'ahasengerwa (cyane cyane ingenzi kuri **Antene ya Cassegrain** n'izindi antene zigarura urumuri)
- Sesengura uburyo feed ihagaze
- Suzuma ingaruka za **umuyobozi w'ishushoumutwaro**
4. Ingingo z'ingenzi z'imyitozo y'ubwubatsi
1. Ibiranga inshuro:
Inyongera ya antena ifite isano ikomeye (nk'uko inyongera ya antena ya 40GHz izagabanuka kuri 30GHz).
2. Ibintu bifitanye isano n'ibidukikije:
Aho ikoranabuhanga rishyirwa, aho rihurira n'ibindi, bizagira ingaruka ku mikorere nyayo y'inyungu.
3. Ibisabwa mu buryo bwo gukora:
Uburyo bwo gutunganya neza butuma igishushanyo mbonera cy’ibishushanyo mbonera gishobora kugerwaho.
Antena ya Cassegrain (26.5-40GHz)
Inama z'abahanga:
Ku byangombwa byihariye nka antene ya **40GHz** mu gice cy’umuraba wa milimetero cyangwa antene ya **Cassegrain** ifite inyungu nyinshi, ni byiza gukorana n’umucuruzi w’inzobere wa **antene za microwave** ufite ubushobozi bwo gupima neza kugira ngo arebe ko ibicuruzwa bikora neza.
Dufite:
- Icyumba cyuzuye cy'ibizamini
- Itsinda ry'abahanga mu gupima
- Ubunararibonye buhanitse mu by'ubwubatsi
Kugira ngo ubone ibisubizo byinshi byo kunoza ubushobozi bwa antene, nyamuneka hamagara itsinda ryacu rya tekiniki.
Kugira ngo umenye byinshi kuri antene, sura:
