Antene ya log-periodic ni antene ifite umugozi munini, ihame ryayo rishingiye ku miterere ya resonance n'imiterere ya log-periodic. Iyi nkuru izakwereka kandi antene za log-periodic zishingiye ku bintu bitatu: amateka, ihame ry'imikorere n'ibyiza bya antene za log-periodic.

Amateka ya antene zikoresha log-periodic

Antene ya Log-periodic ni antene ifite umugozi munini, imiterere yayo ikaba ishingiye ku miterere ya log-periodic. Amateka ya antene za log-periodic ahera mu myaka ya 1950.

Antene ya log-periodic yavumbuwe bwa mbere mu 1957 n'abahanga b'Abanyamerika Dwight Isbell na Raymond DuHamel. Ubwo bakoraga ubushakashatsi muri Bell Labs, bakoze antene ya interineti ibasha gutwikira imirongo myinshi ya frequency. Iyi miterere ya antene ikoresha log-periodic geometry, iyiha imiterere isa y'imirasire mu rugero rwose rwa frequency.

Mu myaka yakurikiyeho, antene za log-periodic zakoreshejwe cyane kandi zigakorwaho ubushakashatsi. Zikoreshwa mu nzego nko mu itumanaho ridafite insinga, kwakira televiziyo na radiyo, sisitemu za radar, gupima radiyo, no mu bushakashatsi bwa siyansi. Imiterere ya antene za log-periodic zifite umurongo mugari ituma zikoresha imirongo myinshi ya frequency, bikagabanya gukenera guhindura umurongo no gusimbuza antene, no kunoza uburyo bworoshye bwo guhindura no gukora neza kwa sisitemu.

Ihame ry'imikorere ya antene ya log-periodic rishingiye ku miterere yayo yihariye. Igizwe n'uruhererekane rw'ibyuma bisimburana, buri kimwe kikiyongera mu burebure n'intera bitewe n'igihe cya logarithmic. Iyi miterere ituma antene ikora itandukaniro ry'ibyiciro ku miterere itandukanye, bityo ikagira imirasire yagutse.

Uko ikoranabuhanga rigenda ritera imbere, uburyo bwo gushushanya no gukora antene za log-periodic bwarushijeho gutera imbere. Antene za none za log-periodic zikoresha ibikoresho bigezweho n'uburyo bwo gukora kugira ngo zinoze imikorere n'ubwizerwe bya antene.

Ihame ry'imikorere yaryo rishobora gusobanurwa muri make ku buryo bukurikira

1. Ihame ry’impinduka: Imiterere ya antene ya log-periodic ishingiye ku ihame ry’impinduka. Ku muvuduko runaka, imiterere ya antene izarema umuzunguruko w’impinduka, bigatuma antene yakira neza kandi igatanga imiraba ya electromagnetic. Mu gushushanya neza uburebure n’intera y’amabati y’icyuma, antene za log-periodic zishobora gukora mu byiciro byinshi by’impinduka.

2. Itandukaniro ry'icyiciro: Igipimo cya log-periodic cy'uburebure bw'igice cy'icyuma n'intera ya antene ya log-periodic gituma buri gice cy'icyuma gitanga itandukaniro ry'icyiciro ku mibare itandukanye. Iri tandukaniro ry'icyiciro rituma antene ikora neza ku mibare itandukanye, bityo bigatuma habaho imikorere ya bande. Ibice bigufi by'icyuma bikora ku mibare myinshi, mu gihe ibice birebire by'icyuma bikora ku mibare mike.

3. Gupima urumuri: Imiterere ya antene ya log-periodic ituma igira imiterere itandukanye y'imirasire ku mibare itandukanye. Uko imibare ihinduka, icyerekezo cy'imirasire n'ubugari bw'umuraba wa antene nabyo birahinduka. Ibi bivuze ko antene za log-periodic zishobora gusuzuma no guhindura imirasire ku murongo munini w'umuraba.

Ibyiza bya antene za log-periodic

1. Ibiranga umurongo wa interineti: Antene ya Log-periodic ni antene ifite umurongo munini ishobora gutwikira imirongo myinshi ya frequency. Imiterere yayo ya log-periodic ituma antene igira imiterere isa y'imirasire mu cyiciro cyose cya frequency, bikuraho gukenera guhindura frequency cyangwa gusimbuza antene, binoza uburyo bworoshye bwo guhindura no gukora neza kwa sisitemu.

2. Ingufu nyinshi zo gupima no kwakira imirasire: Antene za Log-periodic akenshi zigira ingufu nyinshi zo gupima no kwakira imirasire. Imiterere yazo ituma habaho amajwi menshi mu byiciro bitandukanye by'amajwi, bigatuma imirasire ikomeye n'ubushobozi bwo kwakira imirasire.

3. Kugenzura icyerekezo: Antene za log-periodic akenshi ziba zerekeza mu cyerekezo, ni ukuvuga ko zifite ubushobozi bukomeye bwo kwakira imirasire cyangwa kwakira mu byerekezo bimwe na bimwe. Ibi bituma antene za log-periodic zikwiriye gukoreshwa mu bikorwa bisaba icyerekezo cyihariye cy’imirasire, nko mu itumanaho, radar, nibindi.

4. Koroshya imiterere ya sisitemu: Kubera ko antene zikoresha log-periodic zishobora gukwirakwira mu buryo bwinshi, imiterere ya sisitemu ishobora koroshywa kandi umubare wa antene ukagabanuka. Ibi bifasha kugabanya ikiguzi cya sisitemu, kugabanya ubukana no kunoza uburyo bwo kwizera.

5. Imikorere yo kurwanya ingaruka mbi: Antene ya Log-periodic ifite imikorere myiza yo kurwanya ingaruka mbi mu mubare munini w'amajwi. Imiterere yayo ituma antene ibasha gukusanya neza ibimenyetso by'amajwi bidakenewe no kunoza uburyo sisitemu irwanya ingaruka mbi.

Muri make, iyo hakozwe neza uburebure n'intera by'amabati y'icyuma, antene ya log-periodic ishobora gukora mu byiciro byinshi bya resonant frequency, ifite imiterere ya wide-band, ubushobozi bwo kwiyongera no gukoresha imirasire neza, kugenzura icyerekezo, imiterere yoroshye ya sisitemu no gukumira ingaruka. Ibi bituma antene za logarithmic periodic zikoreshwa cyane mu itumanaho ridafite insinga, radar, ubushakashatsi bwa siyansi n'ahandi.
