Igishushanyo 1 kirerekana igishushanyo mbonera gisanzwe cyerekana igishushanyo, gifite uburebure burebure kandi bugufi bwubatswe hamwe nu mwanya hagati. Aka gace karashobora gukoreshwa mugukwirakwiza amashanyarazi.

igishushanyo 1. Geometrie ya antenne ikunze kugaragara cyane.

Imbere-impera (Y = 0 ifunguye mumaso mu ndege ya xz) antenne iragaburirwa. Impera ya kure mubisanzwe ni umuzenguruko mugufi (metallic encosure). Umuhengeri urashobora gushimishwa na dipole ngufi (igaragara inyuma ya cavit slot antenna) kurupapuro, cyangwa nundi muyoboro.

Gutangira gusesengura antenne ya shusho 1, reka turebe moderi yumuzingi. Umuhengeri ubwawo ukora nkumurongo wohereza, kandi ibibanza biri mumurongo wizuba birashobora kubonwa nkibintu bisa (parallel). Umuhengeri ni muto-uzunguruka, bityo ikigereranyo cyumuzunguruko kigereranijwe cyerekanwe mubishusho 1:

igishushanyo cya 2.

Ahantu haheruka ni intera "d" kugeza ku ndunduro (ikaba izunguruka-ngufi, nkuko bigaragara ku gishushanyo cya 2), kandi ibice byerekana umwanya "L" hagati yundi.

Ingano ya groove izatanga umurongo wuburebure. Ubuyobozi bwa wavelegnth nuburebure bwumurongo muri waveguide. Ubuyobozi bwumurongo () nigikorwa cyubugari bwumurongo ("a") nuburebure bwumwanya wubusa. Kuburyo bwiganje bwa TE01, uburebure bwumurongo ni:

Intera iri hagati yanyuma nuheruka "d" ihitamo kuba uburebure bwa kane. Imiterere yuburyo bwumurongo woherejwe, kimwe cya kane-uburebure bwumurongo muto-inzitizi yumurongo woherejwe hepfo ni gufungura uruziga. Kubwibyo, Igishushanyo cya 2 kigabanuka kuri:

ishusho 3. Icyerekezo cyumuzunguruko cyerekana icyerekezo ukoresheje igihembwe-cyerekezo gihinduka.

Niba ibipimo "L" byatoranijwe kuba igice cyumurambararo, noneho ibyinjijwe ž ohmic impedance ireba igice cyumurambararo wa z ohms. "L" nimpamvu yo gushushanya kuba hafi igice cyumuraba. Niba antenne ya waveguide yakozwe muri ubu buryo, noneho ibibanza byose bishobora gufatwa nkibisanzwe. Kubwibyo, ibyinjira byinjira hamwe nimbogamizi yikintu cya "N" cyerekanwe umurongo gishobora kubarwa vuba nka:

Iyinjizwa ryimbogamizi ya waveguide nigikorwa cya slot impedance.

Nyamuneka menya ko ibipimo byavuzwe haruguru bifite agaciro gusa kumurongo umwe. Mugihe inshuro ziva aho ngaho igishushanyo mbonera cya waveguide gikora, hazabaho gutesha agaciro mumikorere ya antene. Nkurugero rwo gutekereza kubyerekeranye ninshuro ziranga umurongo wateganijwe, ibipimo byintangarugero nkigikorwa cyinshuro bizerekanwa muri S11. Umuhengeri wagenewe gukora kuri 10 GHz. Ibi bigaburirwa ibiryo bya coaxial hepfo, nkuko bigaragara ku gishushanyo cya 4.

Igicapo ca 4. Antenne yashizwe kumurongo igaburirwa nigaburo rya coaxial.

Igisubizo cya S-parameter cyerekanwe hepfo.

ICYITONDERWA: Antenna ifite igitonyanga kinini cyane kuri S11 kuri 10 GHz. Ibi birerekana ko ingufu nyinshi zikoreshwa mumirasire kuriyi radiyo. Umuyoboro wa antenne (niba usobanuwe nka S11 uri munsi ya -6 dB) uva kuri 9.7 GHz ukagera kuri 10.5 GHz, ugatanga umurongo wa 8%. Menya ko hari na resonance hafi 6.7 na 9.2 GHz. Munsi ya 6.5 GHz, munsi ya cutoff waveguide inshuro kandi hafi nta mbaraga zirasa. Umugambi wa S-parameter werekanye hejuru utanga igitekerezo cyiza cyukuntu umurongo wagutse washyizwe kumurongo wumuvuduko urasa.

Imirasire-itatu-yerekana imishwarara yerekana umurongo werekana hepfo (ibi byabazwe ukoresheje numero ya electromagnetic yamashanyarazi yitwa FEKO). Inyungu yiyi antenne igera kuri 17 dB.
