Amakuru - Uburyo bune bwibanze bwo kugaburira antenne ya microstrip

Imiterere ya aantenne ya microstripmuri rusange igizwe na dielectric substrate, radiator hamwe nicyapa cyubutaka. Ubunini bwa substrate ya dielectric ni buto cyane kurenza uburebure bwumuraba. Icyuma cyoroshye cyane munsi ya substrate ihujwe na plaque y'ubutaka. Kuruhande rwimbere, icyuma cyoroshye gifite ishusho yihariye gikozwe muburyo bwo gufotora nka radiator. Imiterere yisahani irasa irashobora guhinduka muburyo bwinshi ukurikije ibisabwa.
Ubwiyongere bwa tekinoroji ya microwave hamwe nuburyo bushya bwo gukora bwateje imbere iterambere rya antenne ya microstrip. Ugereranije na antenne gakondo, antenne ya microstrip ntabwo ari nto gusa mubunini, urumuri muburemere, hasi mumwirondoro, byoroshye guhuza, byoroshye guhuza, bidahenze, kandi bikwiriye kubyara umusaruro mwinshi, ariko kandi bifite ibyiza byo gutandukanya amashanyarazi atandukanye.

Uburyo bune bwibanze bwo kugaburira antenne ya microstrip nuburyo bukurikira:

1. (Kugaburira Microstrip): Ubu ni bumwe muburyo bukunze kugaburira antenne ya microstrip. Ikimenyetso cya RF gishyikirizwa igice kimurika cya antenne binyuze mumurongo wa microstrip, mubisanzwe binyuze muguhuza umurongo wa microstrip nuduce twinshi. Ubu buryo buroroshye kandi bworoshye kandi bukwiranye no gushushanya antenne nyinshi za microstrip.

2.. Ubu buryo bushobora gutanga impedance nziza ihuye nubushobozi bwimirasire, kandi irashobora kandi kugabanya ubugari bwa horizontal na vertical ubugari bwa lobes kuruhande.

3.. Irashobora gutanga impedance ihanitse ihuza umurongo mugari, kandi irakwiriye mugushushanya antenne yagutse.

4 .. Ubu buryo busanzwe butanga impedance nziza hamwe nubushobozi bwimirasire, kandi birakwiriye cyane cyane mubihe bikenewe antenne imwe.

Uburyo butandukanye bwo kugaburira bizagira ingaruka ku guhuza impedance, ibiranga inshuro, imikorere yimirasire nuburyo bwa antenne.

Nigute ushobora guhitamo coaxial feed point ya microstrip antenna

Mugihe utegura antenne ya microstrip, guhitamo aho ibiryo bigaburira coaxial nibyingenzi kugirango imikorere ya antenne ikorwe. Hano hari uburyo bwateganijwe bwo guhitamo ingingo zo kugaburira coaxial kuri antenne ya microstrip:

1. Ibi bifasha kunoza imishwarara ya antenne no guhuza impedance.

3. Aho ikigezweho ari kinini: Ingingo yo kugaburira ya coaxial irashobora gutoranywa hafi yumwanya aho antenna ya microstrip irenze kugirango ibone imbaraga zumuriro mwinshi kandi neza.

4. Umwanya w'amashanyarazi wa zeru muburyo bumwe: Muburyo bwa antenne ya microstrip, niba ushaka kugera kumirasire yuburyo bumwe, aho kugaburira coaxial mubisanzwe byatoranijwe kumwanya wumuriro wa zeru muburyo bumwe kugirango ugere kubintu byiza bihuye nimirasire. biranga.

6. Reba icyerekezo cy'ibiti: Niba hakenewe ibiranga imirasire hamwe nubuyobozi bwihariye, ahantu ho kugaburira coaxial hashobora gutoranywa ukurikije icyerekezo cya beam kugirango ubone imikorere ya antenna yifuzwa.

Mubikorwa nyabyo byo gushushanya, mubisanzwe birakenewe guhuza uburyo bwavuzwe haruguru no kumenya uburyo bwiza bwo kugaburira coaxial point ukoresheje isesengura ryigero hamwe nibisubizo nyabyo byo gupima kugirango ugere kubishushanyo mbonera n'ibipimo byerekana antenne ya microstrip. Muri icyo gihe, ubwoko butandukanye bwa antenne ya microstrip (nka antenne ya patch, antenne ya helical, nibindi) irashobora kugira ibitekerezo bimwe byihariye muguhitamo aho ibiryo bigaburira coaxial, bisaba gusesengura no gutezimbere ukurikije ubwoko bwa antenne yihariye kandi Porogaramu. .

Itandukaniro riri hagati ya antenne ya microstrip na antenna

Antenna ya Microstrip na antenna ya patch ni antenne ebyiri zisanzwe. Bafite itandukaniro n'ibiranga:

1. Imiterere n'imiterere:

- Antenna ya microstrip mubusanzwe igizwe na microstrip patch na plaque y'ubutaka. Igice cya microstrip gikora nk'ikintu kimurika kandi gihujwe na plaque y'ubutaka binyuze kumurongo wa microstrip.

2. Ingano n'imiterere:

- Antenne ya Microstrip ni ntoya mubunini, ikoreshwa kenshi mumirongo ya microwave, kandi ifite igishushanyo cyoroshye.

- Patch antenne irashobora kandi gushushanywa kugirango igabanuke, kandi mubihe bimwe na bimwe, ibipimo byayo bishobora kuba bito.

3. Urutonde rwinshuro:

- Umuvuduko wa antenne ya microstrip irashobora kuva kuri megahertz amagana kugeza kuri gigahertz nyinshi, hamwe nibiranga umurongo mugari.

- Patch antenne mubisanzwe ifite imikorere myiza mumirongo yihariye kandi ikoreshwa mubisabwa byihariye.

4. Gahunda yumusaruro:

- Antenne ya Microstrip isanzwe ikorwa hifashishijwe tekinoroji yumuzunguruko wacapwe, ishobora gukorwa cyane kandi ifite igiciro gito.

- Antenne yamashanyarazi ikozwe mubikoresho bishingiye kuri silikoni cyangwa ibindi bikoresho bidasanzwe, bifite ibyo bisabwa kugirango bitunganyirizwe, kandi birakwiriye kubyara umusaruro muto.

5. Ibiranga polarisiyasi:

- Antenne ya Microstrip irashobora gushushanyirizwa kumurongo cyangwa guhuza uruziga, kubaha urwego runaka rwo guhinduka.

- Ibiranga polarisiyasi ya antenne yubusanzwe biterwa nuburyo imiterere ya antenne kandi ntabwo byoroshye nka antenne ya microstrip.

Muri rusange, antenne ya microstrip na antenne ya patch iratandukanye muburyo, imiterere yumurongo, hamwe nuburyo bwo gukora. Guhitamo ubwoko bwa antenne bukwiye bigomba gushingira kubisabwa byihariye byo gusaba no gutekereza.
