Chii chinonzi Microstrip Antenna? Maumbirwo, Nheyo yeKushanda uye Mashandisirwo

Pfupiso yeChigadzirwa neTekinoroji

Antena ye microstrip i antenna yakarongwa yakagadzirwa ne conductive radiating patch, dielectric substrate, uye ground plane. Chigamba ichi chinowanzo dhindwa kune rumwe rutivi rwe substrate, nepo ground plane ichiiswa kune rumwe rutivi. Chimiro ichi chinoita kuti antenna ive yakatetepa, yakareruka, uye yakakodzera kuiswa pamapuratifomu akati sandara kana akakombama zvishoma.

Mukushanda kweRF engineering, microstrip antennas dzinokosheswa nekuti dzinogona kubatanidzwa nema microwave circuits, phased arrays, radomes, uye compact system housings. Hunhu hwavo hwemwaranzi hunogona kugadziriswa kuburikidza ne patch geometry, substrate material, feeding method, array arrangement, uye mechanical layout.

Chimiro Chekutanga cheMicrostrip Antenna

Antena ye microstrip inowanzo shandiswa ine zvikamu zvitatu zvikuru. Chigamba chesimbi chepamusoro chinoshanda sechinhu chinopa chiedza. Chigadziko che dielectric chinotsigira chigamba uye chinokanganisa bandwidth, kushanda zvakanaka, uye saizi. Nzvimbo yepasi inobatsira kutsanangura maitiro emwaranzi uye inoparadzanisa antenna kubva panzvimbo inokwidzwa.

Chigamba chinopenya	Kazhinji ine denderedzwa, yakatenderera, kana kuti yakagadzirwa nenzira yakasarudzika kuti iite frequency uye polarization inodiwa.
Chigadziko che dielectric	Yakasarudzwa zvichienderana nekurasikirwa kweRF, dielectric constant, ukobvu, bandwidth, uye zvinodiwa nezvakatipoteredza.
Ndege yepasi	Inopa gwara rekutarisa uye inobatsira pakushanda kwemwaranzi kwakasimba.
Chimiro chekudya	Inogona kushandisa tambo ye microstrip, coaxial probe, aperture coupling, kana proxing yepedyo zvichienderana nedhizaini yaro.

Antena yeMicrostrip Inoshanda Sei?

Kana simba reRF rikaiswa muchikamu, simba remagetsi rinoumbwa pakati pechikamu nepasi. Mwaranzi inonyanya kuitika pedyo nemucheto wechigamba, uko nzvimbo inopinza magetsi inopinda munzvimbo yakapoteredza.

Kuwanda kwekushanda kwacho kwakabatana zvakanyanya nehukuru hwechigamba, kusachinja-chinja kwedielectric yesubstrate, uye ukobvu hwesubstrate. Kune chigamba cherectangular, kureba kweresonant kunowanzoenderana nehafu yehurefu hwewavelength hunotungamirwa mukati mesubstrate.

Mumagadzirirwo chaiwo, zviyero zvekupedzisira zvinofanirwa kugadziriswa nekuti dielectric loading, nzvimbo yekudyisa, imba, radome material, uye zvivakwa zvesimbi zviri pedyo zvinogona kukanganisa mashandiro akayerwa.

Nzira Dzakajairika Dzekudya

Nzira Yekudyisa	Kubatsirwa Kwakajairika	Kufunga Nezveinjiniya
Kudya Kwemitsetse yeMicrostrip	Chimiro chakadhindwa chiri nyore uye kubatanidzwa kwePCB kuri nyore.	Mwaranzi yemuchina wekudyisa uye kufananidza kunofanira kudzorwa nokungwarira.
Chikafu cheCoaxial Probe	Sarudzo yenzvimbo yekudyisa inochinjika yekuenzanisa impedance.	Kuungana kwemuchina uye inductance yeprobe zvinogona kukanganisa bandwidth.
Chikafu chakabatanidzwa neAperture	Kuparadzaniswa kwakanaka pakati pe network yekudyisa nechinhu chinopenya.	Maumbirwo akaomarara akawanda uye kutonga kwakasimba kwekugadzira.
Feed Yakabatana Nepedyo	Inogona kubatsira kuvandudza bandwidth mumagadzirirwo akasarudzwa.	Zvinoda kurongeka kwakarurama kwezvikamu uye kusarudzwa kwezvinhu.

Zvakanakira uye Zvisina Kukwana

Zvakanakira Chimiro chisina kusimba uye chakareruka. Yakakodzera masisitimu eRF akamanikana uye microwave. Inoenderana nematunhu eplanar uye magadzirirwo earray. Inogona kutsigira polarization yakatsetseka kana yakatenderera zvichienderana nekugadzirwa kwayo. Chimiro chinochinjika uye marongerwo ekubatanidza zvakagadzirwa.

Miganhu Bandwidth inogona kunge yakamanikana kupfuura mamwe marudzi ehorn kana reflector antenna. Kushanda zvakanaka kunogona kukanganiswa nekurasikirwa kwe dielectric uye kurasikirwa kwe conductor. Kushanda kunoenderana nezvinhu zvepasi, ukobvu, uye zvivakwa zviri pedyo. Zvinhu zvinopisa, zvakatipoteredza, uye zvemakanika zvinofanirwa kutariswa pakushandisa kwakaoma.

Maitiro Akajairika

Nekuda kwechimiro chavo chakarongwa uye kuchinjika kwedhizaini, ma microstrip antenna anoshandiswa mumapuratifomu akawanda eRF nema microwave uko nzvimbo, huremu, uye kubatanidzwa kwakakosha.

Masisitimu eRadarMagumo ekumberi eradar akamanikana, ma "phased arrays", uye mapuratifomu ekuona mafambiro emhepo.	Ndege neDziviriroKuiswa kwechinhu chisina kunyatsojeka uko kureba neuremu zvemakanika zvakakosha.	Kutaurirana Pasina WayaMa microwave links, ma terminal antenna, uye ma integrated communication modules.
Kuyerwa kweAntenaMarabhoritari eRF ekuyedza, kuenzanisa, uye kuongorora nhanho yesystem.	Kufamba uye TelemetryMabhendi akasarudzwa uye zvinodiwa zvekuparadzanisa.	Kubatanidzwa kweSisitimuKuenzanisa mashandiro eantenna nemiganhu yenzvimbo uye puratifomu.

Makaneti eMicrostrip Array

Chinhu chimwe chete chinogona kushandiswa chega, asi masisitimu mazhinji ema microwave anoda kugona kukuru kwekuwedzera simba, kupenda kwakafanana, kana kugona kuskena. Muzviitiko izvi, zvinhu zvakawanda zvepatch zvinogona kurongwa kuitakanyanga ye microstrip array.

Nekudzora nzvimbo yezvikamu, network yekudyisa, amplitude, uye kugoverwa kwezvikamu, mainjiniya vanogona kuwana zvinangwa zvakasiyana zve beamwidth, sidelobe, gain, uye polarization. Microstrip array antennas inowanzo tariswa se radar, satellite communication, electronic measurement, uye compact directional RF systems.
