RF MISO | Gwaro rekusarudza maAntena
A kanyanga yelenziinoshandisa lenzi kudzora kupararira kwechikamu chemagetsi. Mu antenna yehorn yelenzi, horn inovhenekera lenzi ye dielectric inoumba danda rinobuda. Kubatsira kwayo hakusi kungowedzera chete: lenzi inogona kubatsira kugadzira danda rinoenda kune rimwe divi kana kuisa simba rakawanda padanho rakatarwa rekushanda.
Kune mainjiniya eRF nemapoka ekutenga, mubvunzo wekutanga ndewekuti:Ko application yacho inoda danda rekure here kana kuti nzvimbo ine finite focal?Gwaro iri rinotsanangura musiyano, magadzirirwo akakosha, uye zvigadzirwa zviviri zveRF MISO zvinoratidza zvinodiwa zvakasiyana zvekusarudza.

Antena yeLens Inoshanda Sei?
Horn yekudyisa inogadzira wavefront ine phase inosiyana munzvimbo yakavhenekerwa. Lenzi ye dielectric inounza kunonoka kwephase inosiyana-siyana kuburikidza nechimiro chayo, hunhu hwayo, kana zvese zviri zviviri. Pakurongeka kwe collimating, lenzi inotsiva musiyano wenzira neurefu saka wavefront inobuda inenge yakarongwa. Aperture chaiyo, ine finite ichiri kugadzira diffraction uye beam ine upamhi husina zero angular.
Nzvimbo yekudyisa inokosha. Nzvimbo yayo inoshanda inofanira kunge inoenderana nekugadzirwa kwelenzi; nzvimbo yacho haisi iyo inofanira kunge iri paburi rehorn. Kuvhenekerwa kwezvikafu, kurongeka uye nzvimbo inopinda zvinopesvedzera maitiro azvinoita. Tsvagiridzo yeyunivhesiti pamusoro pemasisitimu ehorn-lens inotsanangura hukama uhwu nebasa rayo mukuwana nzvimbo imwe chete inobuda.[1]
Magirazi eRF haagumiri pagirazi re optical. Magadzirirwo ema microwave anogona kushandisa zvinhu zve dielectric zvinoderedza kurasikirwa kwechiedza zvakaita sePTFE kana polyethylene; zvinhu zvakakodzera zvinoenderana nehuwandu, kurasikirwa uye zvinodiwa ne mechanical. Lenzi isinganyanyi kuwedzera simba reRF. Kuvandudzwa kwekuwedzera kwechiedza kunobva mukugoverwa kwemwaranzi uye kushanda kwayo, nekurasikirwa kwezvinhu uye kuratidzwa kwechiedza kuchiripo.
Kuisana kweMadonhwe (Collimation) vs. Kuisa Nzvimbo paMadonhwe (Spot Focusing)
Antena yeRF MISO RM-SFLHA90-25 ine nyanga yegirazi inotarisa nzvimbo. Nzvimbo dzekutarisa chaidzo dzine saizi yakaganhurirwa; tarisiro yenzvimbo yekushanda inofanira kutsanangurwa kune antena yakasarudzwa.
Danda rinotenderera
Kana chinodiwa chiri chekuyerwa kwekutumira kwakanangana kana kuyera antenna, ongorora gain vs frequency, E- uye H-plane beamwidths, sidelobes uye cross-polarization. Danda rakamanikana rinoitawo kuti pointing and fixture alignment ive yakakosha. Usafunge kuti high-gain lens horn inopa daro rakatarwa re near-field focal distance.
Nzvimbo yekuyera yemuno
Nyanga yelenzi inotarisa nzvimbo inoisa chiedza chakatenderedza nzvimbo yakatarwa iri kure. Izvi zvinobatsira pakurongeka kwakakodzera kwemavara echinhu chiri munzvimbo yakasununguka, uko saizi yemuenzaniso uye geometry yekujekesa zvinokanganisa kuyerwa. Tsvagiridzo yekuyerwa kwezvinhu zve microwave yakatarisana inoratidza kuti nei hunhu hwenzvimbo ye focal-plane huchikosha pamwe chete nehukuru hwenzvimbo.[2]
Taura daro rinodiwa uye kuti rinoyerwa sei, mashandisirwo aro, zviyero zvemuenzaniso uye nzvimbo inovhenekerwa inogamuchirwa. Bvunza kana dhayamita yenzvimbo yacho yakatsanangurwa padanho re3 dB, 10 dB, first null, kana chimwe chinodiwa. Manhamba anoshandisa tsananguro dzakasiyana haaenzaniswi zvakananga.
