Iyo antenna yekubatanidza imagetsi yekubatanidza inoshandiswa kubatanidza redhiyo frequency michina uye tambo.Basa rayo guru nderokutumira zviratidzo zvepamusoro-frequency.
Iyo yekubatanidza ine yakanakisa impedance yekufananidza maitiro, ayo anovimbisa kuti chiratidzo chechiratidzo uye kurasikirwa kunoderedzwa panguva yekufambisa pakati pechibatanidza netambo.Ivo kazhinji vane yakanaka yekudzivirira zvivakwa kudzivirira ekunze emagetsi kukanganiswa kubva pakukanganisa chiratidzo chemhando.
Yakajairika antenna yekubatanidza mhando dzinosanganisira SMA, BNC, N-mhando, TNC, nezvimwe, idzo dzakakodzera kune akasiyana maapplication.
Ichi chinyorwa chichakuzivisa iwe kune akati wandei anowanzo shandiswa zvibatanidza:
Connector kushandiswa frequency
SMA Connector
Iyo SMA mhando RF coaxial yekubatanidza ndeye RF/microwave yekubatanidza yakagadzirwa na Bendix uye Omni-Spectra mukupera kwema1950s.Yakanga iri imwe yeainyanyo shandiswa zvibatanidza panguva iyoyo.
Pakutanga, maSMA aibatanidza aishandiswa pa 0.141 ″ semi-rigid coaxial tambo, ainyanya kushandiswa mumicrowave application muindasitiri yemauto, ine Teflon dielectric fill.
Nekuti iyo SMA yekubatanidza idiki muhukuru uye inogona kushanda pamafrequency epamusoro (iyo frequency renji ndeye DC kusvika 18GHz kana yabatanidzwa kune semi-yakaomarara tambo, uye DC kusvika 12.4GHz kana yakabatana kune inochinjika tambo), iri kukurumidza kuwana mukurumbira.Mamwe makambani ave kukwanisa kugadzira SMA zvibatanidza zvakatenderedza DC ~ 27GHz.Kunyangwe kuvandudzwa kwemamillimeter wave connectors (senge 3.5mm, 2.92mm) inoona kuenderana kwemuchina neSMA zvibatanidza.
SMA connector
BNC Connector
Zita rakazara reBNC connector ndiBayonet Nut Connector (snap-fit connector, iri zita rinotsanangura zvakajeka chimiro chechibatanidza ichi), yakatumidzwa zita rebhayonet yayo yekuisa yekukiya nzira uye vagadziri vayo Paul Neill naCarl Concelman.
yakajairika RF yekubatanidza iyo inoderedza wave kuratidza / kurasikirwa.BNC majoini anowanzo shandiswa muzasi kusvika pakati-frequency application uye anoshandiswa zvakanyanya muwireless masisitimu ekutaurirana, terevhizheni, bvunzo michina, uye RF zvemagetsi michina.
BNC zvibatanidza zvakashandiswawo mukutanga komputa network.Iyo BNC yekubatanidza inotsigira masaini ma frequency kubva ku0 kusvika 4GHz, asi inogona zvakare kushanda kusvika 12GHz kana yakakosha yemhando yepamusoro vhezheni yakagadzirirwa iyi frequency ikashandiswa.Kune marudzi maviri ehunhu impedance, anoti 50 ohms uye 75 ohms.50 ohm BNC zvibatanidza zvinonyanya kufarirwa.
N mhando Connector
Iyo N-mhando yekubatanidza antenna yakagadzirwa naPaul Neal kuBell Labs kuma1940s.Type N connectors pakutanga yakagadzirirwa kusangana nezvinodiwa zvemauto nendege minda yekubatanidza radar masisitimu nemimwe midziyo yeredhiyo.Iyo N-mhando yekubatanidza yakagadzirirwa neyakaomeswa yekubatanidza, ichipa yakanaka impedance yekufananidza uye kudzivirira kuita, uye yakakodzera kune yakakwirira simba uye yakaderera frequency application.
Iyo frequency renji yeType N yekubatanidza kazhinji inotsamira pane chaiyo dhizaini uye yekugadzira zviyero.Kazhinji kutaura, N-mhando yekubatanidza inogona kuvhara frequency renji kubva ku0 Hz (DC) kusvika 11 GHz kusvika 18 GHz.Nekudaro, yemhando yepamusoro N-mhando yekubatanidza inogona kutsigira yakakwirira frequency renji, inosvika pamusoro pe18 GHz.Mumashandisirwo anoshanda, N-mhando yekubatanidza inonyanya kushandiswa mune yakaderera kusvika yepakati frequency maapplication, senge isina waya kutaurirana, kutepfenyura, setiraiti kutaurirana uye radar masisitimu.
N mhando yekubatanidza
TNC Connector
Iyo TNC yekubatanidza (Threaded Neill-Concelman) yakagadzirwa pamwe chete naPaul Neill naCarl Concelman mukutanga ma1960s.Iyo vhezheni yakagadziridzwa yeBNC yekubatanidza uye inoshandisa yakarukwa yekubatanidza nzira.
Iyo hunhu impedance ndeye 50 ohms, uye iyo yakakwana yekushanda frequency renji ndeye 0-11GHz.Muiyo microwave frequency bhendi, TNC zvinongedzo zvinoita zvirinani pane BNC zvinongedzo.Iyo ine hunhu hwekuvhunduka kwakasimba kuramba, kuvimbika kwepamusoro, yakanakisa mechaniki uye magetsi zvivakwa, nezvimwewo, uye inoshandiswa zvakanyanya mumidziyo yeredhiyo uye zviridzwa zvemagetsi kubatanidza RF coaxial tambo.
3.5mm Chibatanidza
Iyo 3.5mm yekubatanidza iredhiyo frequency coaxial yekubatanidza.Iyo dhayamita yemukati yekunze conductor ndeye 3.5mm, iyo hunhu impedance ndeye 50Ω, uye nzira yekubatanidza ndeye 1/4-36UNS-2 inch thread.
Pakati pe-1970s, makambani eAmerican Hewlett-Packard neAmphenol (akanyanya kugadzirwa neHP Kambani, uye kugadzirwa kwekutanga kwakaitwa neAmphenol Company) yakatanga 3.5mm yekubatanidza, ine frequency yekushandisa inosvika 33GHz uye ndiyo yekutanga. radio frequency inogona kushandiswa mumillimeter wave bhendi.Imwe ye coaxial connectors.
Zvichienzaniswa neSMA connectors (kusanganisira Southwest Microwave's "Super SMA"), 3.5mm zvinobatanidza zvinoshandisa air dielectric, zvine makondukita akakora ekunze kupfuura maSMA connectors, uye ane simba remuchina ari nani.Naizvozvo, kwete chete kuita kwemagetsi kuri nani pane iyo yeSMA yekubatanidza, asi iyo mechanic kusimba uye kudzokorora kwekuita zvakare kwakakwira kupfuura iyo yeSMA yekubatanidza, zvichiita kuti ive yakakodzera kushandiswa muindasitiri yekuyedza.
2.92mm Chibatanidza
Iyo 2.92mm yekubatanidza, vamwe vagadziri vanoidaidza kuti 2.9mm kana K-mhando yekubatanidza, uye vamwe vagadziri vanoidaidza kuti SMK, KMC, WMP4 yekubatanidza, nezvimwewo, iredhiyo frequency coaxial yekubatanidza ine yekunze conductor yemukati dhayamita ye2.92mm.Hunhu Iyo impedance ndeye 50Ω uye nzira yekubatanidza ndeye 1/4-36UNS-2 inch thread.Chimiro chayo chakafanana ne3.5mm yekubatanidza, idiki chete.
Muna 1983, Wiltron senior engineer William.Old.Field akagadzira new 2.92mm/K-type connector zvichibva pakupfupikisa uye kukunda zvakambounzwa mamillimeter wave connectors (K-type connector ndiyo trademark).Iyo yemukati conductor dhayamita yeichi chinongedzo ndeye 1.27mm uye inogona kubatanidzwa neSMA zvibatanidza uye 3.5mm zvinongedzo.
Iyo 2.92mm yekubatanidza ine yakanakisa kushanda kwemagetsi mu frequency renji (0-46) GHz uye inofambirana nemakanika nemaSMA majoini uye 3.5mm zvinobatanidza.Nekuda kweizvozvo, yakakurumidza kuve imwe yeanonyanya kushandiswa mmWave connectors.
2.4mm Chibatanidza
Kuvandudzwa kweiyo 2.4mm yekubatanidza kwakaitwa pamwe chete neHP (yakatangira yeKeysight Technologies), Amphenol uye M/A-COM.Inogona kufungidzirwa sediki vhezheni ye3.5mm yekubatanidza, saka kune yakakura kuwedzera kwepamusoro frequency.Ichi chinongedzo chinoshandiswa zvakanyanya mu50GHz masisitimu uye chinogona kushanda kusvika ku60GHz.Kuti ugadzirise dambudziko iro SMA uye 2.92mm zvibatanidza zvinokanganisa kukuvadza, iyo 2.4mm yekubatanidza yakagadzirirwa kubvisa zvikanganiso izvi nekuwedzera ukobvu hwekunze kwemadziro ekubatanidza uye kusimbisa mapini echikadzi.Iyi dhizaini yekuvandudza inobvumira iyo 2.4mm yekubatanidza kuti iite zvakanaka mune yakakwirira-frequency application.
Iko kuvandudza kweantenna majoini kwakabuda kubva kune akareruka shinda dhizaini kuenda kune akawanda marudzi epamusoro-inoshanda zvinobatanidza.Nekufambira mberi kwetekinoroji, vanobatanidza vanoramba vachitevera hunhu hwehukuru hudiki, huwandu hwepamusoro uye bandwidth hombe kuzadzisa zvinoshanduka zvinodikanwa zvekutaurirana zvisina waya.Imwe neimwe yekubatanidza ine hunhu hwayo uye mabhenefiti mune akasiyana ekushandisa mamiriro, saka kusarudza iyo chaiyo antenna yekubatanidza kwakakosha kwazvo kuve nechokwadi chemhando uye kugadzikana kwekufambiswa kwechiratidzo.
