Ubwa mbere, ihame rya antene:

1.1 Ibisobanuro bya antene:
Igikoresho gishobora gutangaza neza imiraba ya elegitoronike mu cyerekezo runaka mu isanzure cyangwa gishobora kwakira neza imiraba ya elegitoronike mu cyerekezo runaka mu isanzure.

1.2 Imikorere ya antena:

Ø Guhindura ingufu – guhindura umuraba uyobowe n'umuraba w'ikirere cyigenga; Imirasire iyobora (kwakira)- ifite icyerekezo runaka.

1.3 Ihame ry'imirasire ya antena:

1.4 Ibipimo bya Antena

Igipimo cy'imirasire

Ø Ubugari bw'igice cy'umuraba w'ingufu, igipimo cy'imbere n'inyuma;

Ø uburyo bwo gutandukanya amoko, ivangura rishingiye ku moko;

Ø Igipimo cy'ubuyobozi, inyungu ya antene;

Ø Agace k'ibanze, agace k'inyongera, gufunga agace k'inyongera, kuzura nta kintu na kimwe, kumanuka kw'umuraba…

Ibipimo by'uruziga

Igipimo cy'umuraba uhagaze wa VSWR, igipimo cyo kugarura Γ, igihombo cyo kugaruka kwa RL;

Ø Impedance yinjiye Zin, gutakaza kwa transmission TL;

Ø kwitandukanya na Iso;

Ø Intermodulation ya gatatu idakora PIM3…

Antena yo ku ruhande

Ubugari bw'umurabyo utambitse

Igipimo cy'imbere n'inyuma: Gisobanura igipimo cy'imbaraga z'imirasire y'imbere kuri antene n'imbaraga z'imirasire y'inyuma muri ± 30°.

Isano iri hagati y'ubwiyongere n'ingano ya antene n'ubugari bwa beamwidth

Gutera "ipine" kuzura, niko ikimenyetso gikomeza kwiyongera, niko ingano ya antene iba nini, kandi ubugari bw'imirasire burushaho kuba buto;

Ingingo nke z'ingenzi zo kongera antene:

Antene ni igikoresho kidakora kandi ntigishobora gukora ingufu. Kubona antene ni ubushobozi bwo gushyira ingufu mu buryo bunoze kugira ngo zitange cyangwa zakire imiraba ya elegitoroniki mu cyerekezo runaka.

Ø Inyungu ya antene iterwa no gushyira ibintu bihindagurika. Uko inyungu irushaho kuba nyinshi, niko uburebure bwa antene buba burebure. Ongera inyungu ho 3dB hanyuma wongere inshuro ebyiri ijwi.

Uko antene irushaho kwiyongera, niko icyerekezo kirushaho kuba cyiza, niko ingufu zirushaho kwiyongera, kandi igice cyayo kirushaho kuba gito.

1.5 Ibipimo by'imirasire

Polarization: yerekeza ku nzira cyangwa impinduka ya vector y'amashanyarazi mu kirere.

1.6 Ibipimo by'Urugendo

Igihombo cyo kugaruza

Icya kabiri, ibikoresho bya antene

2.1 Uburyo bwo Kwita Antena:

Ibyiciro bya Antena: ODP (Antena y'aho hanze iherereye), OOA (Antena y'aho hanze iherereye), IXD (Antena yo mu gisenge cy'inzu), OCS (Antena y'aho hanze iherereye), OCA (Antena y'aho hanze iherereye), OYI (Antena ya Yagi yo hanze), ORA (Antena yo hanze ishyirwa hejuru), IWH (Antena yo mu nzu ishyizwe ku rukuta) n'ibindi.

Igice cy'ingufu Inguni: 032,065,090,105,360 (antene yo guhagarara) 020,030,040,050,060,075,090,120,160,360 (antene isubiramo)

Uburyo bwa Polarization: R (polarization ebyiri), V (polarization imwe)

Antena yo hejuru

                                                                       Antena iri ku rukuta

Antena ya Yagi

Antena y'urukuta

Antena y'umurongo ugororotse ya Broadband Omnidirectional Log-Periodic Antena Plate Antena

3.1 Igitandukanya imbaraga

Imashini igabanya ingufu z'ikimenyetso kimwe cy'umusaruro mu bisohoka bibiri cyangwa byinshi. Mu by'ukuri ni imashini ihindura impedance.

Ese igikoresho cyo kugabanya ingufu gishobora guhindurwa kugira ngo gisimbuze icyo gikoresho cyo kugabanya ingufu?

Iyo ikoreshejwe nk'icyuma gihindura imiterere y'amashanyarazi, ntabwo isaba gusa kwitandukanya cyane n'umuraba uri hasi, ahubwo inareba ibisabwa kugira ngo ihangane n'imbaraga nyinshi. Ukurikije ko imiyoboro y'amashanyarazi akoreshwa cyane adahuye n'umuraba munini uhagaze; Kubera imbaraga nke zikoreshwa n'iki gice gihindura imiterere y'amashanyarazi, ntabwo twagira inama yo gukoresha iki gice gihindura imiterere y'amashanyarazi kugira ngo gisimbuze iki gice gihuza amashanyarazi.

Igabanyirizwa ry'ingufu zo mu mwobo

Icya kane, itangira ry'ihuza ry'amakuru

4.1 Igikoresho cyo guhuza

Ø Coupler ni ubwoko bw'igice gikwirakwiza ingufu z'ikimenyetso cyinjiye binyuze mu ngufu z'amashanyarazi n'imbaraga za rukuruzi kugira ngo bibe igice cy'umusaruro w'ingufu, n'ibindi bisigaye by'umusaruro kugira ngo birangize ikwirakwizwa ry'amashanyarazi.

Ø Ikwirakwizwa ry'ingufu z'icyuma gihuza amashanyarazi ntirigabanyijemo kabiri. Rizwi kandi nka power sampler.

Igikoresho cyo guhuza icyerekezo

Udukoresho duhuza icyerekezo gikunze gukoreshwa hamwe n'icyerekezo cyagenwe cy'urujya n'uruza rw'ibimenyetso bya mikoroonde mu gupima, intego nyamukuru ni ugutandukanya no gutandukanya ikimenyetso, cyangwa kuvanga ibimenyetso bitandukanye, mu gihe nta mutwaro w'imbere, utwo dukoresho duhuza icyerekezo akenshi tuba dufite umuyoboro w'ibyambu bine.

Igikoresho cyo gukurura mu mwobo

Ibiranga: Ingufu nyinshi, ubushobozi bwo gutakaza bike.

Impamvu:

1. Umwobo wuzuyemo umwuka, kandi mu nzira yo kohereza, ikwirakwira ry'amakuru riterwa n'umwuka uba uri hasi cyane.

2. Umukandara w'insinga ufatanye muri rusange ukozwe mu cyuma gitwara amashanyarazi gifite ubushobozi bwiza bwo gutwara amashanyarazi (nk'icyuma gitwikira umuringa), kandi igihombo cy'icyuma gitwara amashanyarazi muri rusange ni gito cyane.

3. Ubwinshi bw'aho hantu buherereye, ubushyuhe buhita bushira. Ihangana n'imbaraga nyinshi.

Attenuator

Ø Attenuator ni ikintu gifite impande ebyiri

Ibikoresho bigabanya ubushyuhe bikunze gukoreshwa cyane ni ibigabanya ubushyuhe.

Attenuator ya coaxial ikoreshwa mu buhanga, igizwe n'urusobe rw'attenuation rwa "π" cyangwa "T".

Ibikoresho bigabanya ubukana bwa coaxial ubusanzwe bigira ubwoko bubiri bw'ibigabanya ubukana buhamye n'ibihindagurika.

Ø Ibikoresho bigabanya ubushyuhe bikoreshwa cyane cyane mu kugenzura ingufu zo kohereza ibimenyetso bya mikoroonde mu buryo bwo kubitahura no gukoresha ingufu zirenze urugero, bityo bikongera urwego rwo gupima ibimenyetso, nk'ibipimo by'amashanyarazi, ibipimo bya spectrum, amplifiers, receivers, n'ibindi.

衰减器

Ø衰减器是二端口互易元件

Ø衰减器最常用的是吸收式衰减器.

Ø工程中通常使用的是同轴型衰减器，由 “π” 型或 “T” 型衰减网络组成。

Ø同轴衰减器通常有固定及可变衰减两种。

Ø衰减器主要用于检测系统中控制微波信号传输能量、消耗超额能量，因而扩展信号测量的动态范围，诸如功率计，频谱分析仪，放大器，接收器等。
