RF Antennas: Misimboti, Mhando, uye Zvishandiso

Radio Frequency (RF) antennas zvinhu zvakakosha mumasisitimu emazuva ano ekutaurirana, achiita basa rakakosha mukufambisa uye kugamuchirwa kwemafungu emagetsi. Kubva panharembozha kuenda kukukurukurirana setiraiti, RF antennas inofambisa kufambiswa zvisina waya kweruzivo munzvimbo dzakakura. Ichi chinyorwa chinoongorora zvakakoshesesa misimboti yeRF antennas, marudzi awo akasiyana, uye mashandisiro awo mundima dzakasiyana. Pamusoro pezvo, isu tinosimbisa maitiro ekubatana neakakodzera PCB mugadziri anogona kusimudzira RF antenna kugadzirwa.

Kunzwisisa RF Antennas

Chii chinonzi RF Antenna?

An RF antenna chishandiso chinoshandura simba remagetsi kuita mafungu emagetsi uye zvichipesana. Inoshanda setransducer, ichibvumira masaini kuti afambiswe uye agamuchirwe pasina waya. Kushanda uye kushanda kweiyo antenna yeRF kunoenderana nekugadzirwa kwayo, zvinhu, uye kuwanda kwemasaini ainobata.

Nheyo dzeRF Antenna Operation

RF antennas inoshanda zvichibva pane akati wandei akakosha misimboti, kusanganisira:

• Mapatani eMwaranzi : Mapatani emwaranzi eantenna anotsanangura kuti anoburitsa sei simba munzira dzakasiyana, dzinowanzo miririrwa mu polar kana Cartesian coordinates, zvichiratidza simba rechiratidzo pamakona akasiyana.

• Kufananidza Impedance : Kuti ishande zvakanaka, impedance yeantenna inofanira kuenderana ne impedance yetambo yekutumira uye mudziyo wakabatana. Kusaenderana kwe impedance kunogona kutungamira kuratidzwa kwechiratidzo, kurasikirwa nesimba, uye kudzikira kwekushanda.

• Kuwana : Kuwana kweAntenna kunoyera kuti antenna inogona sei kutungamira mafungu eredhiyo munzira yakati zvichienzaniswa neradiator yeisotropic, iyo inoburitsa zvakaenzana munzira dzese. Kuwana kunowanzo ratidzwa muma decibels (dB).

• Polarization : Polarization yeantenna inoreva kurongeka kwesimba remagetsi remafungu emagetsi. Mhando dzakajairika dzepolarization dzinosanganisira linear, denderedzwa, uye elliptical.

• Bandwidth : Bandwidth yeantenna inoratidza huwandu hwemafrequencies ayo inogona kushanda zvinobudirira. Bandwidth yakafara inobvumira antenna kutsigira nzira dzakawanda dzekutaurirana.

Mhando dzeRF Antennas

Kune akawanda marudzi eRF antennas, imwe neimwe yakagadzirirwa mashandisirwo chaiwo. Pazasi pane mamwe emhando dzinowanzo zivikanwa, pamwe chete nezvakanakira uye zvazvakaipira:

1. Dipole Antennas

A dipole antenna ine maviri conductive zvinhu, anowanzo kurongeka mumutsara wakatwasuka. Iyo ndeimwe yeakareruka uye anonyanya kushandiswa antenna dhizaini, anowanzo shandiswa muamateur redhiyo, kutepfenyura kweterevhizheni, uye kutaurirana pasina waya. Iyo dhizaini iri nyore inobvumira kuvakwa kuri nyore, zvichiita kuti iwanikwe kune akawanda maapplication. Nekudaro, dipole antennas ane mashoma bandwidth uye kuwana kana ichienzaniswa neakanyanya kuomarara antenna, ayo anogona kudzikisira kushanda kwawo mune mamwe mamiriro.

2. Monopole Antennas

A monopole antenna inonyanya hafu-dipole, ine chinhu chimwe uye ndege yepasi. Aya antennas anowanzo kuwanikwa munharembozha uye nemotokari-yakaiswa masisitimu ekutaurirana, uko compact size uye kubatanidzwa kwakakosha. Yavo omni-directional radiation pateni inobvumira kufambisa kwechiratidzo kunoshanda munzira dzakasiyana. Zvakangodaro, kuita kwemonopole antennas kunogona kukanganiswa zvakanyanya nemhando yendege yepasi, iyo yakakosha pakuita kwakaringana.

3. Yagi-Uda Antennas

Iyo Yagi-Uda antenna ine akati wandei zvinhu, zvinosanganisira chinofambiswa chinhu, vatungamiriri, uye varatidziri, zvichiita kuti ive yakanyanya kutungamira. Iyi dhizaini yeantenna inonyanya kushanda pakugamuchira terevhizheni uye redhiyo yeamateur, uko kutaurirana kwenguva refu kunodiwa. Kuwana kwepamusoro uye kurongeka kweYagi-Uda antennas inobvumira kuvandudzwa kwesimba rechiratidzo pamusoro pemarefu madaro. Zvisinei, kuoma kwavo mukugadzira uye kurongeka kunogona kuva chidimbu, chinoda kunyatsoiswa uye kugadzirisa.

4. Patch Antennas

Maantenna epatch, anozivikanwawo sema microstrip antennas, akati sandara uye akamanikana, anoshandiswa kakawanda mumafoni, GPS, uye network dzisina waya. Maantenna aya ane patch inofambisa pa dielectric substrate, zvichiita kuti ave akareruka uye ari nyore kugadzira. Kusashanda kwawo kunobvumira kubatanidzwa mumidziyo yakasiyana-siyana. Zvisinei, maantenna epatch anowanzova nebandwidth shoma uye gain yakaderera kana zvichienzaniswa nedzimwe mhando dzeantenna, izvo zvinogona kukanganisa kushanda kwawo mumashandisirwo chaiwo. Kushandisa TMM substrates kuderedza saizi yeantenna kunoda kuti geometry yeantenna iongororwe nehukobvu hwe dielectric hwakasarudzwa uye kushivirira kunotarisirwa kwekugadzira.

5. Loop Antennas

Loop antennas inoratidzwa ne loop yewaya kana conductor iyo inogona kushandiswa kune zvese kutapurirana uye kugamuchira. Inowanzo shandiswa muRFID masisitimu uye yakaderera-frequency application, loop antennas inopa compact size uye yakatwasuka kuvaka, zvichiita kuti zvive nyore kuendesa. Ivo vanonyanya kushanda pakugamuchira yakaderera-frequency masaini, kupa mhinduro inoshanda kune akasiyana mafomu. Zvakangodaro, loop antennas anowanzo ratidza yakaderera kuwana uye kugona zvichienzaniswa neakanyanya dhizaini, izvo zvinogona kudzikisira kuita kwavo kwese.

6. Nyanga Antennas

Nyanga antenna zvimiro zvakatsva zvakagadzirirwa kutungamira masaisai eredhiyo, anonyanya kushandiswa muma microwave frequency. Inozivikanwa nekuwana kwavo kwakakwirira uye kwakanakisa kurongeka, manyanga antenna anoshanda mumashandisirwo anoda kutariswa kwechiratidzo chekufambisa. Bandwidth yavo yakakura inoita kuti ive yakakodzera kune dzakasiyana siyana, ichiwedzera kuita kwavo kwakasiyana-siyana. Nekudaro, iyo bulkiness yenyanga antennas inogona kukanganisa, sezvo isingakodzeri kune compact zvishandiso uye ingangoda imwe nzvimbo yekuisa.

Kuti uwane ongororo yakakwana yekugadzira, shandisa chinyorwa chino pamwe chete nekugadzirwa kwePCB ye microwave uye RF uye PCB ye microwave paunenge uchitarisa zvinodiwa pa stackup, kuunganidza, kana bvunzo.

Zvishandiso zveRF Antennas

Sezvo michina yeIoT ichiwanda, RF antennas inoita basa rakakosha mukugonesa kutaurirana kusina waya pakati pemidziyo. Antenna akaderera-simba anoshandiswa mumasensa uye akangwara madivayiri ekufambisira dhata.

RF Antenna Circuit Board Procurement

Kana zvasvika pakugadzira RF antennas, kutengwa kwemabhodhi emhando yepamusoro-soro kwakakosha kuti uwane kuita kwakaringana. Kusarudza mupi wePCB akakodzera kunosanganisira kufunga zvinhu zvakaita semhando yezvinhu, kugona kugadzira, uye kugona kugadzirisa madhizaini kune chaiwo maapplication. Mafungiro akakosha mukuita uku kwekutenga zvinhu anosanganisira kuve nechokwadi chekuti PCB inogona kutsigira yakaderera-kurasikirwa zvinhu zvakakodzerwa neRF zvikumbiro, pamwe neruzivo rwemupi nehunyanzvi hwekugadzira hunyanzvi hunochengetedza kutendeseka kwechiratidzo. Pamusoro pezvo, kushandirapamwe nemutengesi anopa kukurumidza prototyping kunogona kufambisa dhizaini yedhizaini, zvichibvumira kugadzirisa nekukurumidza kuzadzisa maitiro ekuita. Pakazere, hunyanzvi hwekutengwa kweRF antenna wedunhu mabhodhi kwakakosha mukusimudzira kushanda uye kuvimbika kweasina waya yekutaurirana masisitimu.

Sei Utisarudzire sePCB Mutengesi?

Semugadziri weRF antenna, kusarudza akakodzera PCB mutengesi kwakakosha kuti uve nechokwadi chemhando uye kushanda kwezvigadzirwa zvako. Ichi ndicho chikonzero kubatana nesu kuchigona kubatsira maitiro ako ekugadzira:
