Chinobatanidza antenna chinobatanidza chemagetsi chinoshandiswa kubatanidza michina yemafrequency eredhiyo netambo. Basa rayo guru nderekutumira masaini ane mafrequency akakwira.
Chinobatanidza chine hunhu hwakanaka hwekufananidza impedance, izvo zvinoita kuti kuratidzwa kwechiratidzo nekurasikirwa kwacho kuderedzwa panguva yekufambiswa pakati pechinobatanidza netambo. Kazhinji zvine hunhu hwakanaka hwekudzivirira kukanganiswa kwemagetsi kubva kunze kuti kusakanganisa kunaka kwechiratidzo.
Mhando dzekubatanidza antenna dzinosanganisira SMA, BNC, N-type, TNC, nezvimwewo, dzakakodzera zvinodiwa zvakasiyana zvekushandisa.
Chinyorwa chino chichakuzivisawo kune akawanda ma connectors anoshandiswa kazhinji:
Kushandiswa kweconnector kakawanda
Chinongedzo cheSMA
Chinobatanidza cheSMA type RF coaxial iRF/microwave connector yakagadzirwa neBendix neOmni-Spectra kuma1950 ekupedzisira. Chaive chimwe chezvinobatanidza zvainyanya kushandiswa panguva iyoyo.
Pakutanga, maSMA connectors aishandiswa patambo dze coaxial dzine 0.141″ dzakasimba zvishoma, dzainyanya kushandiswa muma microwave muindasitiri yemauto, neTeflon dielectric fill.
Nekuti chinobatanidza cheSMA chidiki uye chinogona kushanda pamafrequencies akakwira (frequency range iri DC kusvika 18GHz kana chakabatana netambo dzakaomarara, uye DC kusvika 12.4GHz kana chakabatana netambo dzinochinjika), chiri kukurumidza kufarirwa. Mamwe makambani ava kukwanisa kugadzira zvibatanidza zveSMA zvakapoteredza DC~27GHz. Kunyangwe kugadzirwa kwezvinobatanidza zvemamilimita (senge 3.5mm, 2.92mm) kunofunga kuti zvinoenderana neSMA connectors.
Chinobatanidza cheSMA
BNC Connector
Zita rakazara reBNC connector ndiBayonet Nut Connector (snap-fit connector, zita iri rinotsanangura zvakajeka chimiro cheiyi connector), rakatumidzwa zita rekuti bayonet mounting locking mechanism uye vagadziri vayo Paul Neill naCarl Concelman.
chinobatanidza cheRF chinowanzo shandiswa chinoderedza kuratidzwa/kurasikirwa kwemafungu. Zvinobatanidza zveBNC zvinowanzo shandiswa mumashandisirwo efrequency yakaderera kusvika pakati uye zvinoshandiswa zvakanyanya mumasisitimu ekutaurirana asina waya, materevhizheni, michina yekuyedza, uye michina yemagetsi yeRF.
Makomputa eBNC aishandiswawo mumakomputa ekutanga. BNC connector inotsigira ma signal frequency anotangira pa 0 kusvika pa 4GHz, asi inogonawo kushanda kusvika pa 12GHz kana shanduro yepamusoro yakagadzirirwa iyi frequency ikashandiswa. Kune mhando mbiri dze characteristic impedance, dzinoti 50 ohms uye 75 ohms. Makomputa eBNC e50 ohm anonyanya kufarirwa.
N mhando yekubatanidza
Chinobatanidza antenna cherudzi rweN chakagadzirwa naPaul Neal kuBell Labs kuma1940. Zvinobatanidza zveType N pakutanga zvakagadzirwa kuti zvisangane nezvinodiwa nemauto nendege zvekubatanidza masisitimu eradar nezvimwe zvishandiso zveredhiyo. Chinobatanidza cherudzi rweN chakagadzirwa nekubatana kwakarukwa, kuchipa kuenderana kwakanaka kweimpedance uye kudzivirira, uye chakakodzera kushandiswa nesimba rakawanda uye frequency yakaderera.
Kuwanda kwema frequency eType N connectors kunowanzoenderana nedhizaini chaiyo uye mwero wekugadzira. Kazhinji, ma N-type connectors anogona kufukidza huwandu hwema frequency kubva pa 0 Hz (DC) kusvika 11 GHz kusvika 18 GHz. Zvisinei, ma N-type connectors emhando yepamusoro anogona kutsigira ma frequency akakwira, achisvika pamusoro pe 18 GHz. Mumashandisirwo anoshanda, ma N-type connectors anonyanya kushandiswa muma frequency akaderera kusvika pakati nepakati, akadai sekutaurirana pasina waya, nhepfenyuro, kutaurirana kwesatellite uye radar systems.
Chinobatanidza chemhando yeN
TNC Connector
Chinobatanidza cheTNC (Threaded Neill-Concelman) chakagadzirwa pamwe chete naPaul Neill naCarl Concelman kutanga kwema1960. Ishanduro yakavandudzwa yechinobatanidza cheBNC uye inoshandisa nzira yekubatanidza ine threaded.
Impedance ine hunhu hwe50 ohms, uye huwandu hwemafrequency ekushanda hwakanyanya i0-11GHz. Mu microwave frequency band, TNC connectors dzinoshanda zviri nani pane BNC connectors. Ine hunhu hwekudzivirira kuvhunduka kwakasimba, kuvimbika kwakanyanya, hunhu hwakanaka hwemakanika nemagetsi, nezvimwewo, uye inoshandiswa zvakanyanya mumidziyo yeredhiyo nemidziyo yemagetsi kubatanidza tambo dzeRF coaxial.
Chinobatanidza che3.5mm
Chinobatanidza che3.5mm chinobatanidza cheredhiyo neredhiyo. Dhayamita yemukati memubati wekunze i3.5mm, hunhu hweimpedance i50Ω, uye nzira yekubatanidza ishinda ye1/4-36UNS-2 inch.
Pakati pemakore ekuma1970, makambani ekuAmerica eHewlett-Packard neAmphenol (akanyanya kugadzirwa neHP Company, uye kugadzirwa kwekutanga kwakaitwa neAmphenol Company) akatanga chinobatanidza che3.5mm, chine frequency yekushanda inosvika 33GHz uye ndiyo frequency yeredhiyo yekutanga inogona kushandiswa mu millimeter wave band. Imwe ye coaxial connectors.
Zvichienzaniswa nezvinobatanidza zveSMA (kusanganisira "Super SMA" yeSouthwest Microwave), zvinobatanidza zve3.5mm zvinoshandisa mhepo ine dielectric, zvine maconductor ekunze akakora kupfuura zvinobatanidza zveSMA, uye zvine simba remakanika riri nani. Saka, kushanda kwemagetsi hakusi kwega kuri nani pane kwezvinobatanidza zveSMA, asiwo kugara kwenguva refu kwemakanika uye kugona kudzokorora kushanda kwakakwira kupfuura kwezvinobatanidza zveSMA, zvichiita kuti zvive zvakakodzera kushandiswa muindasitiri yekuedza.
Chinobatanidza che2.92mm
Chinobatanidza che2.92mm, vamwe vagadziri vanochidana kuti 2.9mm kana kuti K-type connector, uye vamwe vagadziri vanochidana kuti SMK, KMC, WMP4 connector, nezvimwewo, iradio frequency coaxial connector ine dhayamita yemukati yeconductor yekunze ye2.92mm. Hunhu Impedance i50Ω uye nzira yekubatanidza ishinda ye1/4-36UNS-2 inch. Chimiro chayo chakafanana nechinobatanidza che3.5mm, chidiki chete.
Muna 1983, mainjiniya mukuru weWiltron William.Old.Field akagadzira chinobatanidza chitsva che2.92mm/K-type zvichibva pakupfupikisa nekukunda zvibatanidza zvemafungu zvema millimeter zvakambotangwa (chinobatanidza cheK-type ndicho chiratidzo chekutengeserana). Dhayamita yemukati me conductor yechinobatanidza ichi i1.27mm uye inogona kubatanidzwa nezvinobatanidza zveSMA nezvinobatanidza zve3.5mm.
Chinobatanidza che2.92mm chine mashandiro akanaka emagetsi muhuwandu hwema frequency (0-46) GHz uye chinoshanda nemakanika nemaSMA connectors nema 3.5mm connectors. Nekuda kweizvozvo, chakakurumidza kuva chimwe chezvinobatanidza zvemmWave zvinoshandiswa zvakanyanya.
Chinobatanidza che 2.4mm
Kugadzirwa kwechinobatanidza che2.4mm kwakaitwa pamwe chete neHP (yakatangira Keysight Technologies), Amphenol uye M/A-COM. Chinogona kufungidzirwa sechidiki pane chinobatanidza che3.5mm, saka pane kuwedzera kukuru kwefrequency yakanyanya. Chinobatanidza ichi chinoshandiswa zvakanyanya mumasisitimu e50GHz uye chinogona kushanda kusvika ku60GHz. Kuti tigadzirise dambudziko rekuti zvinobatanidza zveSMA ne2.92mm zvinogona kukuvara, chinobatanidza che2.4mm chakagadzirirwa kubvisa zvikanganiso izvi nekuwedzera ukobvu hwemadziro ekunze echinobatanidza uye kusimbisa mapini echikadzi. Dhizaini iyi itsva inobvumira chinobatanidza che2.4mm kuti chishande zvakanaka mumashandisirwo ehigh-frequency.
Kugadzirwa kwezvinobatanidza antenna kwashanduka kubva pakugadzirwa kweshinda dziri nyore kusvika kumhando dzakasiyana dzezvinobatanidza zvinoshanda zvakanyanya. Nekufambira mberi kwetekinoroji, zvinobatanidza zvinoramba zvichitevera hunhu hwehukuru hudiki, frequency yakakwira uye bandwidth yakakura kuti zvisangane nezvinodiwa zvekutaurirana kwewaya isina waya. Chinobatanidza chimwe nechimwe chine hunhu hwacho uye zvakanakira mumamiriro akasiyana ekushandisa, saka kusarudza chinobatanidza antenna chakakodzera kwakakosha zvikuru kuve nechokwadi chekuti kutumira kwechiratidzo kwakanaka uye kwakasimba.
