Antennas anonzwisisa nharaunda yavo. Naizvozvo, kana paine kanyanga pane iyo PCB, dhizaini yekugadzira inofanira kutora zvinodiwa neantenna, sezvo izvi zvinogona kukanganisa zvakanyanya kushanda kusina wireless kwechigadzirwa. Kuchenjerera kukuru kunofanirwa kutorwa kana uchibatanidza maantena mune zvigadzirwa zvitsva. Kunyangwe izvo zvinhu, huwandu hwematanho uye ukobvu hwePCB zvinogona kukanganisa mashandiro eiyo antenna.

Isa antenna kuti uvandudze mashandiro

Antennas anoshanda nenzira dzakasiyana, uye zvinoenderana nekuti maantenna anopenya sei, vangangoda kuiswa munzvimbo dzakatarwa – padivi pfupi, padivi refu, kana pakona yePCB.

Kazhinji, kona yePCB inzvimbo yakanaka yekuisa antenna. Izvi zvinodaro nekuti nzvimbo yekona inobvumira kanyanga kuve nemikahwira munzira shanu dzenzvimbo, uye chikafu cheiyo antenna chiri munzira yechitanhatu.

Vagadziri veantenna vanopa sarudzo dzekumakondenendi munzvimbo dzakasiyana, saka vagadziri vezvigadzirwa vanogona kusarudza iyo antenna inonyatsoenderana nemamiriro avo. Kazhinji, data remugadziri rinoratidza dhizaini iyo, kana ikateverwa, inopa kuita kwakanaka kwazvo.

Chigadzirwa dhizaini ye4G uye LTE inowanzo shandisa akawanda maantena kuvaka MIMO masisitimu. Mumagadzirirwo akadaro, kana ma antenna mazhinji achishandiswa panguva imwe chete, maanti anowanzoiswa pamakona akasiyana ePCB

Izvo zvakakosha kuti usaise chero chinhu mukati memunda uri padyo neiyo antenna sezvo inogona kukanganisa mashandiro ayo. Naizvozvo, iyo antenna yakatarwa inotsanangura saizi yenzvimbo yakachengetwa, inova nzvimbo iri padyo uye yakatenderedza antenna iyo inofanirwa kuchengetedzwa kure nezvinhu zvesimbi. Izvi zvinoshanda kune yega yega rukoko muPCB. Uye zvakare, usaise chero chinhu kana kuisa masikirini munzvimbo ino pane chero chikamu chebhodhi.

Iyo antenna inopenya kune iyo yepasi ndege, uye iyo yepasi ndege inoenderana nekuwanda iko iko iyo antenna inoshanda. Naizvozvo, zvinokurumidza kupa saizi chaiyo uye nzvimbo yepasi ndege yeiyo antenna yakasarudzwa.

Ndege yepasi

Kukura kwendege yepasi kunofanirwawo kufunga nezve chero waya dzinoshandiswa kutaurirana nemudziyo uye mabhatiri kana tambo dzemagetsi dzinoshandiswa kusimbisa mudziyo. Kana iyo ndege yekumisikidza iri yehukuru hwakaringana, ita shuwa kuti tambo nemabhatiri akanangana nemudziyo hazvina zvazvinobatsira paiyo kanyanga

Dzimwe antenna dzakabatana neyendege ndege, zvinoreva kuti iyo pcb pachayo inova chikamu chevhu cheiyo antenna kuenzanisa iyo yazvino antenna, uye yakaderera rukoko rwePCB inogona kukanganisa mashandiro eiyo antenna. Muchiitiko ichi, zvakakosha kuti usaisa mabhatiri kana maLCDS pedyo neantenna.

Pepa remugadziri wedata rinofanirwa kugara richitsanangura kana antenna ichida radiation yepasi uye, kana zvakadaro, saizi yendege yekudzika inodiwa. Izvi zvinogona kureva kuti nzvimbo yemahara inofanira kukomberedza kanyanga.

Pedyo nezvimwe zvinhu zvePCB

Izvo zvakakosha kuchengetedza antenna kure kubva kune zvimwe zvikamu zvinogona kukanganisa nzira iyo antenna inopenya. Chinhu chimwe chete chekucherechedza mabhatiri; LCD simbi zvinhu, senge USB, HDMI uye Ethernet zvinongedzo; Uye mheremhere kana yepamusoro-soro inoshandura zvinhu zvine chekuita nekuchinja magetsi.

Chinhambwe chakakodzera pakati peantenna nechimwe chikamu chinosiyana zvichienderana nekukwirira kwechikamu. Kazhinji, kana mutsetse wakadhirowewa pamadhigirii masere kusvika pazasi peiyo antenna, chinhambwe chakachengeteka pakati pechinhu uye kanyanga kana iri pazasi pemutsara.

Kana paine mamwe ma antenna ari kushanda munzvimbo dzakafanana padyo, zvinogona kukonzera maantena maviri kuti asvibise, sezvo achipesana nemwaranzi yemumwe neumwe. Isu tinokurudzira kuti izvi zvidzikiswe nekuzviparadzanisa angangoita -10 dB maantenna pane mafrifti anosvika ku1 GHz uye angangoita -20 dB antennas pa20 GHz. Izvi zvinogona kuitwa nekusiya imwe nzvimbo pakati peiyo antenna kana nekuitenderedza kuitira kuti iiswe 90 kana 180 madhigirii zvakasiyana kubva kune imwe.

Gadzira mitsetse yekufambisa

Mitsetse yekufambisa ndeye rf tambo dzinoendesa simba reRF kuenda nekubva kune antenna kuendesa masaini kuredhiyo. Matanho ekutakurisa anoda kugadzirwa kuti ave makumi mashanu, zvikasadaro anogona kuratidza masaini kudzokera kuredhiyo uye kukonzera kudonha kwechiratidzo-ku-ruzha reshiyo (SNR), iyo inogona kuita kuti inogamuchira redhiyo ishaye zvazvinoreva. Reflection inoyerwa sevoltage stand wave ratio (VSWR). Yakanaka pcb dhizaini inoratidzira yakakodzera VSWR zviyero zvinogona kutorwa kana uchiedza iyo antenna.

Tinokurudzira kugadzirwa kwakanyatsogadzirwa kwemitsara yekutumira. Kutanga, tambo yekufambisa inofanirwa kunge yakatwasuka, nekuti kana iine makona kana kukombama, inogona kukonzera kurasikirwa. Nekuisa maperforations zvakaenzana pamativi ese ewaya, ruzha uye kurasikirwa kwechiratidzo kunogona kukanganisa kuita kweantenna kunogona kuchengetwa kusvika padanho rakaderera, sezvo mashandiro anogona kuvandudzwa nekuparadzanisa ruzha runopararira pamwe newaya dziri pedyo kana pasi.

Tambo dzekufambisa dzakatetepa dzinogona kukonzera kurasikirwa kukuru. Iyo RF inoenderana nechinhu uye hupamhi hwetambo yekufambisa inoshandiswa kugadzirisa iyo antenna kuti ishande pane hunhu impedance ye50 ω. Saizi yetambo yekutapurirana inokanganisa mashandiro, uye tambo yekutapurirana inofanira kunge ipfupi sezvinobvira kuita kwakanaka kweantenna.

Nzira yekuita sei zviri nani?

Kana iwe ukabvumira ndege yekumisa pasi uye woisa antenna munzvimbo yakanaka kwazvo, une mavambo akanaka, asi pane zvakawanda zvaunogona kuita kuti uvandudze kuita kwe antenna. Iwe unogona kushandisa network inofananidzwa kurongedza antenna – izvi zvinotsiva kune imwe nhanho kune chero zvinhu zvingakanganisa kuita kweantenna.

Chinhu chakakosha cheRF chikamu ndeye antenna, inofanana netiweki uye kuburitsa kwayo RF. Chimiro chinoisa zvikamu izvi pedyo chinoderedza kurasikirwa kwechiratidzo. Saizvozvowo, kana dhizaini yako ichisanganisira inoenderana netiweki, iyo antenna ichaita nemazvo chaizvo kana iyo wiring kureba ichienderana iyo yakatsanangurwa mune iyo inogadzira zvigadzirwa zvirevo.

Iyo casing yakatenderedza PCB inogonawo kusiyana. Antenna masiginecha haagone kufamba nesimbi, saka kuisa antenna muimba yesimbi kana imba ine simbi zvinhu hazvibudirire.

Zvakare, chenjerera kana uchiisa antenna pedyo nenzvimbo yepurasitiki, sezvo izvi zvichigona kukonzera kukuvadza kwakakura pakuita kweantenna. Mamwe mapurasitiki (semuenzaniso, fiberglass yakazadzwa naironi) anorasika uye anogona kuora muiyo ANTENNA’s RF chiratidzo. Purasitiki ine yakakwira dielectric nguva dzose kupfuura mhepo, iyo inogona kukanganisa zvakanyanya chiratidzo. Izvi zvinoreva kuti iyo kanyanga inorekodha yakakwira dielectric inogara iripo, ichiwedzera kureba kwemagetsi kweiyo antenna uye ichidzikisa kuwanda kwemayera emagetsi.
