Antenna ya log-periodic ni antenne yagutse ya antenne ihame ryakazi rishingiye kuri resonance nuburyo bwa logique. Iyi ngingo izanakumenyesha kuri antenne ya log-periodic uhereye kubintu bitatu: amateka, ihame ryakazi nibyiza bya antenne ya log-periodic.

Amateka ya antenne yigihe-gihe

Antenna yigihe-ni antenne yagutse-antenne igishushanyo cyayo gishingiye kumiterere-yigihe. Amateka ya antenne yigihe-gihe yatangiriye muri 1950.

Antenna y'ibihe byavumbuwe bwa mbere mu 1957 n'abashakashatsi b'Abanyamerika Dwight Isbell na Raymond DuHamel. Mugihe bakora ubushakashatsi muri Bell Labs, bakoze antenne yagutse ishobora gutwikira imirongo myinshi. Imiterere ya antenne ikoresha log-periodic geometrie, itanga imirasire isa kumurongo wose.

Mu myaka icumi yakurikiyeho, antenne ya log-period yakoreshejwe cyane kandi yizwe. Zikoreshwa mubice nk'itumanaho ridafite insinga, televiziyo na radiyo yakira, sisitemu ya radar, gupima radiyo, n'ubushakashatsi bwa siyansi. Ikirangantego cyagutse kiranga antenne ya log-periodic ibafasha gupfundika imirongo myinshi yumurongo, kugabanya gukenera guhinduranya inshuro no gusimbuza antene, no kunoza imikorere no gukora neza.

Ihame ryakazi rya antenne yigihe-gihe ishingiye kumiterere yihariye. Igizwe nurukurikirane rw'ibyuma bisimburana, buri kimwe cyiyongera muburebure no gutandukanya ukurikije igihe cya logarithmic. Iyi miterere itera antene kubyara ibice bitandukanye mumirongo itandukanye, bityo ikagera kumirasire yagutse.

Uko ikoranabuhanga rigenda ritera imbere, igishushanyo mbonera nuburyo bwo gukora antenne yigihe-gihe byateye imbere. Antenna igezweho ya antenne ikoresha ibikoresho bigezweho hamwe nuburyo bwo gukora kugirango tunoze imikorere ya antenne kandi yizewe.

Ihame ryakazi rishobora gusobanurwa muri make nkibi bikurikira

1. Ihame rya Resonance: Igishushanyo cya antenne yigihe-gihe ishingiye ku ihame rya resonance. Mugihe cyihariye, imiterere ya antenne izakora rezonant yumurongo, ituma antenne yakira neza kandi ikwirakwiza imiraba ya electronique. Mugushushanya neza uburebure hamwe nintera yimpapuro zicyuma, antenne yigihe-gihe irashobora gukora mumirongo myinshi yumurongo.

2. Itandukaniro ryicyiciro riganisha ku myitwarire ya antenne kuri radiyo zitandukanye, bityo bigatuma ibikorwa-bigari bikora. Ibice bigufi byicyuma bikora kumurongo mwinshi, mugihe ibice birebire byicyuma bikora kumurongo muto.

3. Gusikana ibiti: Imiterere ya antenne yigihe-ituma igira imirasire itandukanye kumirongo itandukanye. Mugihe inshuro zihinduka, icyerekezo cyimirasire nubugari bwa antenna nayo irahinduka. Ibi bivuze ko antenne yigihe-gishobora gusikana no guhindura imirongo hejuru yumurongo mugari.

Ibyiza bya antenne yigihe-gihe

1. Ibiranga umurongo mugari: Antenna ya Log-periodic ni antenne yagutse ishobora gutwikira imirongo myinshi. Imiterere ya log-periodic ituma antenne igira imiterere isa nimirasire yumurongo wose, bikuraho gukenera guhinduranya inshuro cyangwa gusimbuza antene, kunoza imikorere ya sisitemu no gukora neza.

2. Kwunguka kwinshi no gukoresha imirasire: Antenne yigihe-isanzwe ifite inyungu nyinshi nubushobozi bwimirasire. Imiterere yacyo itanga resonance mumirongo myinshi yumurongo, itanga imirasire ikomeye nubushobozi bwo kwakira.

3. Ibi bituma antenne yigihe-ikwiranye na porogaramu isaba imirasire yihariye, nk'itumanaho, radar, nibindi.

4. Koroshya igishushanyo cya sisitemu: Kubera ko antenne ya log-periodic ishobora gukwirakwiza umurongo mugari, igishushanyo cya sisitemu gishobora koroshya kandi umubare wa antene urashobora kugabanuka. Ibi bifasha kugabanya ibiciro bya sisitemu, kugabanya ibintu bigoye no kunoza ubwizerwe.

5. Imikorere yo kurwanya-kwivanga: Antenna ya Log-periodic ifite imikorere myiza yo kurwanya-kwivanga mumurongo mugari. Imiterere yacyo ifasha antenne gushungura neza ibimenyetso byinshyi bidakenewe no kunoza sisitemu yo kwivanga.

Muri make, mugushushanya neza uburebure nintera yimpapuro zicyuma, antenne yigihe-gihe irashobora gukora mumirongo myinshi yumurongo wa resonant, hamwe nibiranga umurongo mugari, inyungu nyinshi hamwe nimirasire yimikorere, kugenzura ibyerekezo, gushushanya sisitemu yoroshye no kurwanya kwivanga . ibyiza byo gukora. Ibi bituma antarine ya logarithmic ikoreshwa cyane mubitumanaho bidafite insinga, radar, ubushakashatsi bwa siyansi nizindi nzego.
